Migbot extruder loading | If the question is "has anyone seen..." my answer is yes. It's not precisely what you show in the drawings, but close enough and for the same purpose.
In the case of a Robo3D R1+ printer, replacing the stock "hexagon" hot end with an E3Dv6 hot end provides for a piece of PTFE tubing inserted into the heat sink. The re... |
Why did my power supply fuse blew out on my Anet A8? | You need to closely look at how to connect to the output connectors. In this case it appears that you have wired it correctly according to the stamped in markings above the connectors. You have chosen not to connect the earth, this is strongly advised.
Did you check if the power switch matches the voltage of your coun... |
How does G-code for belt bed printers work? | Belt printers use existing 3d printer hardware, including controllers and steppers. The Z axis is tilted at 45 degrees (usually). So to answer the first part of your question: yes, you can use G-Code to control the printer, just as you would with an upright printer.
I don't know a good resource that describes everythin... |
Build plate adhesion, PLA | From here: https://io3dprint.com/review-anycubic-i3-mega-ultrabase/
Ultrabase Bed
The Anycubic i3 Mega Ultrabase is the latest version in the Anycubic i3 family. As hinted in the name, the main upgrade from the previous version is the Ultrabase bed. This is a textured coating on the Borosilicate glass bed that m... |
At which point does a delta 3d printer change the G-code in order to work in its non-cartesian design? | The short answer is that the handling of the non-cartesian design is done by the motion-control firmware running on the Arduino.
The long answer:
I don't believe GRBL supports non-cartesian designs, and it is not commonly used for printers. It is more often used for mills, routers, or laser machines. 3D printers will... |
Can I use a 0 mm top layer thickness in Ultimaker Cura to create an open box? | Yes that will work in Ultimaker Cura exactly as you say.
So if you have a solid model of a cube, you select wall thickness, bottom thickness, 0 % infill, and no top layers or top layer size of 0 mm. You will then end up with a box without a top layer, but with walls reaching up to the height of your model. |
Why use G29 during a print? | Now, all of that aside, I guess, in theory, it WOULD be possible for the printer to use these 16 measurements to dynamically ADJUST the height DURING THE PRINT based on where the head is SUPPOSED to be versus where the ACTUAL height of that spot actually IS. However, I cannot find anything that claims this is what happ... |
Does the amount of figures on the board matter? | This would depend on what type of printer you have and to some extent, the design of the printer.
Cartesian (i3 style) - Should not have any issues printing a full bed. I have seen designs and variants of printers where the designer did not make the belts parallel to the travel axis (placing the mounting point on t... |
How to print TPU material with 3D printer | Elastomers do much better on direct-drive heads (pulled to the head by the motor) than on Bowden designs (where the material is pushed to the head by a motor). This is because the flexible TPU or TPE can bend in the guide tube, causing lag during advance/retract changes, and sometimes even bind up during delivery.

Adequate default filament diameter for Anycubic Mega X | Reading all 49 pages of the manual was fruitless. I'm astonished that there is no reference to the filament diameter used in this printer.
From 3dJake's web site comes a confirmation that the printer uses 1.75 mm filament.
It's not a matter of changing a nozzle to use 2.85 mm filament, as the entire filament path is ba... |
Will Mod Podge work with PLA prints? | From what I've read about Mod Podge, it is an adhesive with a vinyl acetate base. As such it is similar to both PVA (used for wash-away support) and ordinary white glue. One of the more common references to the product refers to it not being water proof, although the outdoor version of the product presents as being wat... |
Does Cura have an algorithm for any infill percentage or does it just have specific patterns? | I fear I'm going to deny your question. The infil percentage and the infil pattern are two orthogonal properties, both of which contribute to the strength, density, mass, and print time of an object. Since there's no way for an algo to "know" what your desired outcome is, this can't be done.
Note - I used 'orthogon... |
Why 3d print has an ugly surface? | This appears to be the result of your hot end (nozzle) temperature being slightly too high.
I'd recommend lowering your nozzle temperature by a few degrees and retrying the print. If the quality improves you're good. If it doesn't improve significantly try lowering a few degrees more.
If you lower the nozzle temper... |
Aluminium cube - fan and hotend mount - is it worth it? | I think its only advantage is that it serves to move money from the folks who buy it to the folks that sell it, and that's an advantage purely for the folks that sell it.
"Additional heatsink surface area" is quite doubtful - it would have poor coupling to the actual heatsink. If the actual heatsink is correctly desig... |
Issue crashing Z-axis when I home X or Y axes | Found the issue with help here! My Z-axis homing height was not set - I set it to 4 mm but found that the Z movement is way off (actual Z movement is more like 15 cm!).
I will update to the latest firmware as suggested. |
Extruder doesn't retract on inner wall lines thereby causing stringing | Cura has a setting called Combing that is enabled by default. This stops the printer from retracting if the travel is contained within the walls. It does this to speed up the print but you get oozing during the travel since the plastic is still in the melt zone. You can change this setting to no skin which will stop it... |
When to use 1.75 mm vs 3 mm filament? | There's no appreciable difference. Just use the filament that fits your particular printer.
If you don't yet have a printer, then I'd get one that uses 1.75 mm filament:
1.75 mm is increasingly becoming the "standard", thus being easier to get. Some filaments are not available as 3 mm.
1.75 mm fi... |
How do I give 3D-printed parts in PLA a shiny smooth finish? | PLA parts can be finished with a coat of epoxy like XTC-3D from Smooth-On. This will smooth out the part and give it a pretty nice shine.
I've also had a fair amount of success sanding prints, giving them a coat of automotive filler primer, and using glossy spray paint.
You can also get great results with an acetone ... |
CURA doesn't want print bridges | Nomenclature help
A Layer is everything that is printed between the print head moving upwards.
Layer height is how tall each line is. It is in Quality.
A Wall is made up from lines put down next to each other.
line width is how thick a 1-perimeter-strong wall is in the XY-plane. It should never be smaller than t... |
Settings for CuraEngine | I think the easiest thing is to use the Cura application together with CuraEngine.
If your printer is not supported, you'll need to add it manually by adding a JSON here: https://github.com/Ultimaker/Cura/tree/master/resources/machines
But when you are done you can easily choose all the features you want. For example: ... |
How to control 4 thermistors in a heated bed? | You can use the Klipper firmware which accepts an arbitrary number of heaters.
Then you can write a Klipper macro which takes one input and applies it to each heated bed (or not, as you prefer).
With Klipper you can also add another Arduino and connect it to klipper as well, in case you don't have enough pins on your... |
Calibration print shape | Your calibration shape depends on what you want to calibrate on. Among the most popular:
Benchy as a general "overall" test.
Lattice Cubes for retraction/stringing and overall quality.
Two pillars to test for stringing and temperature/cooling control.
Spikes for retraction, stringing and temperature/cooling control.

Can a heatbed PCB (Prusa Mk2) be straightened out? | Electrical engineer here. There is nothing odd about putting a PCB in an oven. Any surface mount PCB is assembled using a reflow oven which heats all the components, as well as the PCB itself, several degrees for quite some time up to the 'soak' temperature, which is 150 °C.
After that, the PCB (and components, st... |
Increased issues with filament grinding | I've encountered this on my Replicator Dual in the past. I was only using MakerBot branded ABS filament, so it wasn't a quality issue for me.
What I found was that the delrin plunger design that "helps" keep the filament in contact with the drive gear wasn't actually helping. So, I installed the newer assemblies that ... |
G-code commands gets multiplied by random number | I believe that everything after the "*" is a comment. From the random variation, I speculate that the comments for Octoprint are a check code. For other host programs, it is a sequence number.
@oscar linked to a previous answer in a comment which shows that it is a checksum. I will need to check the next time I run... |

Can you put PLA parts in your car (in the sun)? | No, PLA cannot be used in cars standing in the sun. Temperatures can locally get over 50 °C (122 °F).
I have printed sun visor hinge pins from PLA for a car (not exposed to direct sunlight either), but after one day in the sun (it usually doesn't get over 29 °C or about 85 ˚F here too) ... |
Do 3D printers really reach 50 micron (0.05 mm) accuracy? | There's not a simple answer to this question, or if there is, it's "no". However the situation is a lot more complicated. When printer specs cite accuracy like this, they're usually basing the claim on the nominal size of the smallest movements on each axis by one "microstep" of the stepper motors. There's a great arti... |
Is there a lubricant that can be used for linear bearings, bronze sinter bushings and threaded rods alike? | A mid-weight PTFE grease like the popular Superlube will work in all the cases you mention (bearings, screws, and sintered bushings). 3D printer service conditions are quite light-duty as far as lubricants are concerned. You really just need to keep everything a little bit "wet" with oil or grease and performance will ... |
Slic3er throws "AMF parsing requires XML::SAX" | The slic3r software is written in Perl, a programming language that can be expanded with local libraries. XML::SAX is one such library. CPAN is a tool which can be used to retrieve libraries from the CPAN repository (Comprehensive Perl Archive Network, I believe).
I use CPAN is something I do infrequently, so I woul... |
SLS 3D printer to DMLS 3D printer | By just changing powder: No.
Changing the powder, the laser and the chamber, maybe you can get something, but it's not recommended.
DMLS machines use a sealed chamber with a flow of Argon, Nitrogen, or other gas to prevent oxidation of metal powder (and avoid fire or explosions).
Laser power for metal needs to be of hi... |
How to reduce +/- 5 degree temp swings of hotend (after PID tuning) | If you are sure that PID is enabled (and not using bang-bang heating, as this gives a very similar heating profile) and did not fix the fluctuations, the best guess for this phenomenon is that the printer board has incorrect capacitors installed on the printer board. This is not very uncommon and can be found on the in... |
ROKO bed levelling sensor | I can't comment for the specific sensor you have, but in general, yes, if you plug something in backwards you have a chance of breaking it - and whatever you plug it into - permanently.
You might have gotten lucky, though - but short of testing the sensor to see whether it will work there is no way to find out.

Printing 3D letters in any font? | I think @Trish answered your question more specifically, but an alternate route (that I think its simpler assuming you don't mind the learning curve) is using Blender.
Rather than creating an svg in a different software and having to go from something like photoshop to inkscape to tinkercad to your printer software... ... |
What can cause the center of the bed to be higher than the sides? | As the Anycubic Chiron has an automated bed leveling, you can just calibrate that differences in height in the printer's firmware. Here is the official tutorial made by Anycubic :) |
Ideas to tune for 300 % speed | extruder clicking means you're getting backed up, grinding.
Make the hotend hotter so you can melt filament 3X faster than expected; most materials have quite a range; aim high.
Slow down the cooling fan; a lot of them can cool the hotend.
You have a silicone boot on the nozzle? that will help some.

Printer Enclosure Material Selection | To reduce the noise, you could replace the metal linear bearings for plastic ones. This reduces the produced noise considerably from experience. Also, put the printer on damping rubber feet.
Enclosing the printer should be done with care, completely boxing the printer up could lead to increased temperatures of your bo... |
Hemispherical Bowl : how is it possible? | There are several factors playing together. For example orientation, printer & slicer settings and more.
Reminder
First of all, not all overhangs of greater than 45° need support. Many printers manage up to 60°, even 70° is not unheard of - with the right settings. Pretty much all printers manage tiny 90° overhangs... |
The part printed correctly except few layers | This looks like either the nozzle had been clogged for some layers and it resolved itself or the g-code contained incorrect instructions.
I suggest altering your print settings slightly and reslicing, then just printing it again. To get more accuracy on the prints, I suggest a line width of 0.45 mm. |
Trouble uploading Skynet3D to my Anet A8 via Arduino program | Skynet3D was a very old fork from Marlin firmware, all functionality (more specifically for the odd LCD screens used by Anet) have been merged into Marlin firmware. Just get the latest version of Marlin. The current and final release of branch 1.1.x is 1.1.9 further development will be done in 2.0.x. Version 1.1.9 work... |
Repeatedly Clogged Printrbot Simple Extruder | I had a similar issue on my Printrbot Simple Metal. I believe my problem was initially caused by clogged nozzle which I replaced, however the jamming persisted. I can't say for sure that it was acting exactly as you describe but I think it may have been similar. I noticed that the little red insulating sleeve was pushe... |
Printing objects with holes using M3D Printer | Have you tried letting it print a few more layers? It is very common that printers use the first few layers to create a raft, which will make the model adhere better to the bed.
I believe this illustration from Simplify3D displays this well: |
PETG filament doesn't stick reliably to fake Buildtak surface | I have printed kilometers of PETG and found the sweet-spot for my brand to be 240 °C for the hotend and 70 °C for the build plate (for my Ultimaker 3 that is, the extruder temp is 5 °C higher for my home build HyperCube Evolution). The reason for the 70 °C is that the glass temperature of PETG is around... |
How do I decrypt messages on my Repetier firmware? | Looking through the source I found Commands.cpp that has a loop.
void Commands::commandLoop() {

If we find the executeGCode method, we see that it calls:
processMCode(com);
And finding the processMCode method, we have the switch case you ... |
Should I cooldown before shutdown? | Depending on what material you print it it most likely a good idea to let the hotend cool down before shutting off the printer (fan).
For example if you shut down the printer right after you print a PLA part, at 190 - 220 degrees Celsius, your hot end will still be that hot and will suffer heat creep without the fan ... |
How to identify what type of filament an unlabeled spool is | Mick's suggestion is a good one. PLA may shed some color in acetone, but ABS will dissolve completely in a suitable amount of time. If you have dark filament, you can test by flexing the filament until it breaks. ABS will sometimes/often/usually fatigue with a white break line, while PLA does not exhibit this tendency ... |
Printrboard Rev. D - RX1 and TX1 (second serial port) / Marlin | I was able to resolve this issue:
I moved to Marlin 1.1.9 (the final release of the 1.1.x versions).
I made a fork, for those who would like to see the changes. Also summarized below.
The RX1 and TX1 pins are well identified in the question. I connected those directly to the HC-06 bluetooth module (using a voltage d... |
Linear advance calibration technique | The same effect as Marlin's test pattern, with alternation between fast and slow segments, can be achieved with a skewed tower and Cura's overhang settings, providing the opportunity to interactively adjust K value during the print, or insert changes at particular layers in the gcode for automated test towers.
I'm usi... |
Nozzle insulation gone, can the printer be damaged? | Removing the insulation will not damage the printer, although it may affect the quality of the prints. The insulation is, after all, there for a purpose.
Allowing too much heat to escape radiatively from the heater block will reduce the maximum flow rate, since less energy will be available to heat the filament, and y... |
Can closed loop steppers be used for extruders? | Closed loop steppers like S42B are becoming popular for the spatial axes because compensating for skipped steps is the correct way to recover for those axes. For example, if the nozzle knocks into a warped corner of a print and skips, the right thing to do is compensate, commanding additional steps necessary to get to ... |
How to make walls thicker using meshmixer or meshlab | Only today, I learned of a solution for this sort of objective, but it uses Fusion 360 rather than Meshmixer or Meshlab. As your question does not include that program, I'll toss the Meshmixer method.
This image is of the model prior to modification:
When you load your STL file into MM, use Edit, Generate Face Gro... |
How to determine shell thickness for parts? | This totally depends on what you think is acceptable for your print, and what the usage of the print is: is it a structural/functional part or just for aesthetic purposes. There is no general rule of thumb for that. Basically this is a design issue.
If it has to be stiff and may not flex much you would require to use ... |
Adding extra Z-offset to bed for PETG in Slic3r | An extra gap of 0.2 mm on top of your existing gap seems rather illogical as the filament is not squished at the build plate anymore. Furthermore 0.2 mm plus something you already have will soon result in a gap over 75% of your nozzle diameter (including your first layer; note that 75% is considered to be the max for g... |
PETG nozzle clearance and extrusion multiplier | Here is the mental framework that I use to reason about PETG: In a nutshell you want to avoid nozzle contact.
Unlike most other plastics, PETG sticks to hot brass really well and every time the nozzle moves through material it will pick up some of it. Material around the the nozzle then sticks to a random place creati... |
First layer rippling and no filament in the certain areas | From the wispy horizontal lines within the perimeters in your second image, it appears that the nozzle is still oozing material during the travel moves. This is likely causing the hole in the corner and the wispy perimeters too. When the extruder reinserts the filament into the hotend after a travel move, it expects th... |
Resin burns to transparent sheet | The first thing to check is the transparent sheet itself - are there any defects (rough patches, creases, grazes) in the area in which the print was stuck to the "transparent sheet"[1]. This will cause the newly cured layers to cling better to that sheet than they should in that area, and likely caused the failure. If... |
Is my 3D printer totally dead? | I would have posted this as a comment, since it is not a definitive answer to the question, but it was too long for a comment.
Since you were unplugging the fan when the problem started, I would suggest that it is a wiring problem.
The first place I would look is to check the ground connection between the processor... |
Heat sensor problems with Makerbot Replicator 2X | Overall, it is unlikely that the problem is temp sensing accuracy. There are only a few things that will throw off the thermocouple's reading:
Poor thermal coupling between the tip and the hot block, such as if the tip has partially pulled free of the brass thermowell crimp (this will make the hot block hotter than t... |
Hictop prusa I3 clone - broken z axis right bracket bearing | That "plastic coupler thingy" is actually a linear bearing, and it consists of a metal shell, and the metal balls roll between the smooth rod and this shell. The plastic part has a channel that guides the balls in a circle.
It would be best to replace the entire bearing (metal part+balls+plastic liner). It's probably ... |
What determines print start location on the build plate? | So it turns out there are elements from each of the previous answers that make sense here, but its not a clear picture. I've spent a whole lot of time trying to make sense of this. I also upgraded my firmware to Sailfish.
For the MakerBot Replicator (or FastForge Creator) family of 3d printers, the origin of the bu... |
How to print spiral(spring) static? | If you want an helicoidal object which acts relatively rigid, you should pick a plastic which is very rigid to begin with. In the case of 3D printing, probably PLA is the best choice. Make it as thick as you can in all the directions where you have no constraints.
Still, it's an object which will be hardly printable wi... |
What are the appropriate ranges of gear ratios for 1.75 mm and 3 mm filament extruders? | $ \frac{(2.85\ mm)^2}{(1.75\ mm)^2}=2.65$ which is the reduction you would want assuming a 1.75 is direct drive.
In this answer I am comparing the amount of filament flowing though the extruder by using $ \pi \times r^2$. Dividing the 2 values gives the ratio of the 2 speeds. A gear ratio is them used to change the ... |
Flashforge Adventurer 3 Filament feeder loud thumping noise, not enough filament extruded | Advice from another source suggested thoroughly cleaning the feed gear on the bowden extruder. When I looked closely there were plastic flakes all over the mechanism. I used compressed air and a brush to clean it.
I also discovered expert mode in the FlashPrint software, which enabled me to slow down the speed at wh... |
Problem with BLTouch on Ender 3 Pro | For anyone who has this problem in the future my solution was to loosen the screw on top of the touch just a little bit |
Strength of 3D printed Objects | A laser sintered part typically uses what could be described as surface bonding, as it does not melt particularly deeply into the powder. It would not have the same strength characteristics as machined steel or otherwise processed metal. A part constructed from 3d printing using feed metal/welding methods would have mo... |
Use Gcode Extrusion Speed in Calculations | I don't think you're going to find either a firmware feature or a slicer feature that handles specifically what you want to do. The slicer would probably be the best place to put it, and I'd recommend maybe opening a feature request ticket with Ultimaker, because that sounds like an awesome feature.
That being said, t... |
Artillery Sidewinder X1 3DTouch not working | Ok so I did a bit of testing with the wiring and it turns out I just had the 3DTouch in the Z- socket instead of Z+ :-) .
Another idiot mistake from me! |
MK8 versus E3d V6 nozzle | To be successful you would need to ensure that the geometry of the two nozzles are compatible. It is not just the external thread. It includes thread length, internal diameter of the nozzle, whether the hot-end is configured for a PTFE liner, or is an all-metal hot-end, how the back end of the nozzle couples back to th... |
Layer lifted and separated from ESD PLA | The spool kept getting caught on itself and tightening. I unrolled some of it and rewound it and the print came out perfect. @anttix was almost correct with the clog theory. |
Sealant to increase Water-Resistance of SLS print | SLS prints from nylon are somewhat porous. This means, that they will let a stabilizer soak into the outer surface to some degree.
What kind of stabilizer is needed is depending somewhat on the properties you want, but generally I believe these might be useable depending on the viscosity:
2-component resins could be... |
How to move Z-axis to a specificic position (Z-max) after printing? | To move the bed down, you simply instruct the bed to do so after the print.
The best way to do that is add a G-code line to your "end G-code" script you find in your slicer you use.
Just add the line:
G1 Z230 F500
With this command you instruct the bed to lower to your maximum Z height at speed (feed rate) 5... |
How to fix Y layer shift on Creality Ender 3? | You have a case of layer shift. Layer shifts happened to me in 3 ways:
The movement of the axis is hindered. Check if all cables run freely and without any chance to catch! improper cable chains can cause binding and stop the printhead or bed in movement and thus induce a shift.
The acceleration might be too fast. Sh... |
Bed leveling method not working with Repetier firmware 0.92.9? | As a guess, you are using the wrong command. If set for n x n grid, you get 3 point measurement with G29, but that is not auto leveling, it is just setting Z height - based on average height at 3 points.
What you need is G32 S2 with S2 to store result in EEPROM (and therefore you should have EEPROM enabled with auto l... |
Failing y-axis home with loud rattling | From your video, it sounds to me as though the stepper motor is fighting against the bed movement. That would indicate to me the bed rails on the X-axis are not square to the bed movement, which would cause binding of the linear bearings on the bed.
To see if this is the issue, loosen the threaded rods in all six plac... |
Is the Vref trimmer relevant on TMC2208 in UART mode? | The potmeter does not work in UART operation, see e.g. this quote:
You don't have to fiddle with jumpers to set your micro-steps, just
change it in the firmware, and you can dynamically change the amount
of current going to each stepper motor (no more adjusting that small
potentiometer on the driver board) just by sen... |
What is the best way to connect 3D printed parts? | For ABS print, I recommend acetone. It is not a glue, but it will dissolve the plastic a bit and if you apply it to both connecting parts and push them together, they will stay connected after the acetone dries. However, it does not dry very fast and you have to be careful not to destroy the object.
For PLA I usually ... |
How to create an accurate mask for a UV 3D resin DLP printer | I've created software to do just that. See the project on Github: CreateMask. It has a wiki page that explains what to do.
To summarize: you measure the LCD build area using a multi-meter and a light dependent resistor. You do this with low and high intensity masks. You feed the numbers in CSV files to the software, a... |
How do I do multi-colour printing? | There are a few different approaches I've seen which you could look into.
The easiest and most common is multiple extruders, each with a different color of thermoplastic. Tools like Pronterface and Slic3r have built-in support for multiple extruders. With multiple extruders you can get one color per extruder; there's ... |
How is PLA different from ABS material? | Paraphrasing this site. Feel free to add suggestions in the form of comments and I will try to incorporate them.
Summary
ABS: Stronger, machinable, more flexible, and more temperature
resistant than PLA. Typically printed on a heated bed. Warping is a common problem when printing ABS.
PLA: Wider range of filaments a... |
3D printing enclosure with LED indication symbols -- is this possible? | Achieving this with 3D printing would be quite difficult, and you might be better served by creating this effect some other way (I would personally recommend getting some inkjet transparencies and stacking a few layers together: an entirely black layer, and a few layers with the symbols in negative space).
One way tha... |
Print parts fail mid-print | Your printer basically has 2 problems;
stringing, and
layer shifting
The second problem is most probably the result of the first issue. Excessive stringing leads to a lot of material outside the print object, when this clutters, the nozzle could get caught up and cause hindering of movement of a certain axis to res... |
BLTouch calibrated, nozzle still dives into the bed | This answer is intended to be a generic answer for Z-offset determination. The question is not clear on how the Z-offset has been determined. It appears as if this distance is measured, while in reality this cannot be measured.
A touch (or a inductive or capacitive) probe uses a trigger point to determine the distance... |
Why does the print speed change at specific height? (Using Ultimaker Cura slicer) | Not being able to see the rest of the model (from the first image), if looks as if the light green sliced area displaying a lower speed for the top of the cylinder, is the only part that need to be printed to that height (now confirmed in the second image). This speed reduction is done by the slicer and is not specific... |
How to print metal-like parts? | If you'd like to print on RepRap like FDM printers, you cannot print from metal, but you can use some filament that tries to look like metal. I have good experience with Bronzefill, but there are plenty of others, just Google for metal filament 3d printing. Note that sometimes the parts need to be post-processed with a... |
Aggressive resin solvent | Wear Gloves.
Returning is impossible
Resin does not just harden, it polymerizes into shape from monomers in a chemical reaction. That means to break it down, you need to destroy the whole chemistry. There is no solvent that can simply reverse it.
Wiping is easy
As long as the rein is still liquid, you can wipe it off. ... |
Help preventing warping while 3d printing with polypropylene | You should enable the "brim" functionality of your slicer. This adds additional perimeters to the first layer, expanding the base of the model. The larger surface area gives more adhesion. |
Will 3D printing work upside down or in zero gravity? | Yes!
3D Printing upside would only potentially have an issue with the first layer if you're using an extremely large gap on the first layer, however in normal circumstances there's enough pressure that the filament is squished into the bed, if you've got one yourself you can put it on it's side, the question when it co... |
What should the underside of a bridge look like? | The idea of the part fan is to cool the plastic as quickly as possible once it is extruded in order to keep it in the correct spot. The slower that the plastic solidifies, the more the plastic will sag when printing overhangs/bridges. The stock part cooling fan/duct on your printer, Monoprice Maker Select Plus, is not... |
How is FDM Better than CBAM? | Well the CBAM stuff is SUPER new, requires a lot more work done by hand (currently), and is going to be WAY expensive compared to widely used FDM machines.
Seems to me like a carbon fiber mixed filament is a cheaper way to go, with a possible annealing process to get the tensile strength up post-print.
Try locating a... |
What causes this characteristic pattern and what is it called? | These "stretch marks" are typically the result of a nozzle that is a little too close to the build surface. Next time levelling be sure to use a thicker piece of paper or allow for less drag when moving the the paper between nozzle and bed. |
Snap-in clamp geometry | I am sure someone much smarter will be able to point you towards datasheets and maths equations that will tell you exactly what you could/can't do, however, I would say it depends on a few things:
Material - some materials have more give/flexibility, others have less. Depending how hot you expect the caps/surrounding... |
Which 3D printer is good for beginners? | Which printer for a beginner depends far more on the beginner in question than the various printers available.
If you are comfortable assembling parts and figuring things out a number of options exist.
If you need a fully-built object, a number of options exist.
If you require lots of dedicated support, via phone o... |
Top-Down SLA Printer Bulging Issue | Let's look at the problem mathematically:
The bed has a 0 that puts the surface some distance $d_0$ above the surface of the resin, the wiper does put the first layer on that height.
after curing, the printer moves down distance $d_d$ to coat the top surface.
afterwards, the bed lowers back up to $d_0+d_l$ - a thickne... |
(Cura setting) How can I fix this? No top layer | I'm pretty sure the yellow lines are showing the full path of the extruder head, including where it's retracted. Somewhere in Cura's maze of menus, there's an option to turn on/off various displays related to the slicing.
As to why the top layer isn't there -- most likely it's too thin in your source model. You m... |
Resources for making 3d scans of electrically conductive materials? | I have heard of similar scanning not using the electrical connecting but using the capacitance of the metal object to detect it. Capacitive Scanning works by detecting a metal object near the prob so the prob doesn't have to touch the object being scanned |
Order in a line command in G-code | I haven't used every flavor of gcode or firmware, but I've never seen the parameter order be important, provided that:
The G or M code was the initial entry; and
Each parameter was clearly listed with one or more spaces between parameters; and
No spaces were in between the parameter letter and the value.
We use a ... |
Passing from nozzle diameter 0.4 mm to 0.2 mm causing filament jamming in heater | 0.2 mm and 0.4 mm are half the diameter, but the maximum flow is not just half: Flow scales with the area. The 0.4 mm nozzle has an area 4 times as the 0.2 mm one:
$\frac{A_1} {A_2}=\frac {0.2^2}{0.1^2}=4$
You need to reduce print speed or the volumetric flow by this factor or make sure your printer can handle the incr... |
Why is BLTouch Still Probing Off the Bed Even When `NOZZLE_TO_PROBE_OFFSET` is Set? | Did you load the values from firmware after the re-flash? Use M502 to load the values you changed, otherwise it will keep using those from memory. Also set #define Z_SAFE_HOMING, then it will home in the middle of the bed.
Also, with a new carriage for the Hemera, your nozzle is not/might not be in exactly the same pos... |
Embedding nuts and washers into print | I've had good luck with just leaving a hex-shaped hole in the print, and press-fitting in the nut afterwards. You'll want the axis of the bolt to be along the z-axis, and to use a fair amount of infill and shells. I usually use PLA, so YMMV slightly.
You may also want to consider your strain gauge setup carefully. If ... |
Prusa i3 jerking during printing | Well that is unique. I would say if you only see this after the printer has been running a while then your electronics are likely overheating. Put a fan on it and report back.
Otherwise and also I would reflash the electronics.. |
