Getting PLA to stick to a cold bed | Most of the same reccomendations that apply for adhesion to a hot bed apply for a cold one. The first ones to come to mind:
really dial in the nozzle height
make the first layer taller than the rest (e.g.: 0.2mm if the rest of your print is 0.1mm)
print the first layer very slowly
print the first layer at higher tem... |
How to keep Z-axis motor from slipping when powered down | The simple way to do this is to use a self-locking screw pitch. Pretty much any single-start thread using a sliding nut cannot be back-driven so the load will not fall. Normal 8x8 trapezoidal thread screws will easily back-drive because of the steep pitch.
Likewise, a worm drive between the motor and Z stage will hol... |
Affordable 3D printing of reflector | I would not recommend extrusion printers for this, because they are unlikely to produce a smooth enough surface. To get a clean surface, the irregularities have to be a fraction of visible wavelengths, which is to say on the order of 0.01 micron.
Without knowing what sort of reflector you're thinking of (flat? spheric... |
Inexpensive 3D printer for medical applications | I am not an expert but I think you will find that because 3D printers use a layer by layer construction method, and the boundary between the layers creates grooves along the surface or leaves a rough texture on the surface. That the textured surface left by 3D printer construction would trap microbes and make 3D printe... |
PLA coating for water irrigation 3D printed parts | Before worrying too much about the hydrophilic properties of PLA, it might be worthwhile to test a fitting.
First, print a fitting and see that the freshly made print is strong enough to carry the pressure of the water, and the compression force of hose clamp you may need to connect the stiff irrigation hose to the pr... |
slic3r: Can I vary the infill percentage for different heights of my model? | Your question is very similar to Different infill in the same part and Using multiple infill types within one model [duplicate]. The difference is that you specifically ask for Slic3r and a variation in layer height infill percentage.
Actually this answer describes using "helper volumes" in Ultimaker Cura to set dif... |
Should I print in a well ventilated area? | The short answer is: yes, it is always a good idea to print in a well-ventilated area. The longer answer can be articulated as follows:
Definition of "fumes"
"Fumes" is a fuzzy word that from a chemical/physical perspective includes at least three different things:

Where did Marlin get its name? | As far as I know Erik van der Zalm started Marlin. He is from the Netherlands and Zalm translates to "salmon". One of the design goals of Marlin was to make it faster than the other firmware available at that time. And a marlin is a very fast swimming fish.
Some firmwares developed after Marlin also joined this fish t... |

When 3D printing a hollow box, what is the best course of action? | That depends very much on what your goal is with the box. If it needs to be hollow and you don't need any access to the inside (and also prefer it to be printed in one piece) than the answer provided by user77232 would probably be the best.
Alternatively, if you need access to the inside of the box you would probably b... |
Best method to make dissolvable supports? | I've had great success printing with HIPS (high-impact polystyrene) as a support for both PLA and ABS. Most sites recommend it for use with ABS because the materials melt at similar temperatures and work best with heated beds, but I've had good luck using it as a support material with PLA on a bed at 60°C. It doesn't s... |
Sharing a printer over a network | NOTE: This is not from personal experience, but I thought it was worth mentioning:

PID autotune fails under all conditions so far. Any ideas I haven't tried? | Turns out I'm using a 12V hot end and should be using 24V. I looked up the resistance to be sure; so no amount of tuning the PID would fix that. |
3D printer destroys part by lowering nozzle | This is my bet, based on cooling fan failure (I assume it was nozzle fan, not a heatsink fan), though honestly my practical experience with HIPS is zero. Without this fan heated material printed at high angles will definitely curl up, and even flat may be unstable. I suppose it happend, observing layer inconsistency on... |

Bulging filaments - How can catch them before they go in the printer | How to catch and fix these on the fly? That would be difficult..
But this is an issue you really should not have.

Why do different drivers change the noise of steppers? | Stepper motors contain two distinct sets of coils. The current in these coils is governed by your stepper motor driver.
To move the motor in either direction, the coils are being driven one after another, and in different directions.
Imagine this being a normal 3-phase AC motor, but instead of three phases, only two... |
Able to compile, but not upload | I have both the BTT SKR PRO v1.1 and the BTT SKR mini v1.1 (it is unclear which is meant by the OP), and for both you do not upload over the USB, you compile the software into a firmware.bin file which you place onto the microSD card. Once you power the board, the new firmware file will be installed onto your board. |
Is PETG filament food safe? | Many manufactures list their filaments as being food safe, but I would not treat this as "gospel truth". Apparently, the FDA considers PETG to be safe for food contact, but they are probably thinking about injection-moulded and vacuum-formed parts. Unfortunately, an initial search of the FDA's website did not yield any... |
Ender 3 build surface is sticking up in the middle | So your (clone) BuildTak bed surface is not sticking to the bed anymore, time to remove the surface and clean the heatbed and apply a new one. These build surfaces (usually) have a sticky 3M sticker to stick it to the bed (or the surface bottom is covered with a sticky surface). When this sticking layer fails of subseq... |
Extruder prints fine up until further down the print | I used a different heat break with a PFTE lining inside. After that it ran smoothly.

Thermal runaway when power on | Issue is solved!
Root cause was a broken thermistor circuit at board and broken thermistor.
I disconnected all wires and power, measured board and thermistors resistance: E0 = ~120 Ω, (E1 and Bed) = ~700 Ω. I swapped pins for TEMP_0_PIN and TEMP_1_PIN within Marlin for Tevo firmware at pins_RAMPS.h as described in answ... |
Nozzle heats while autoleveling (or before) | I am using CURA as my slicer, and it sets the bed and nozzle temp before printer start code is executed.

Why the Anet A6 can't do .05 layer height | I'm not familiar with the Anet A6 specifically, but as many other things in a 3D printer, the minimum layer height is co-determined by a number of factors. For the Z-axis the factors I am aware of are:
The number of steps in the stepper motor
The geometry of the lead screw
The tolerance with which the lead screw has... |
Why does infill percentage stop the print from sticking to the bed? | The more infill, the more material. The more material, the more stress is inside the part while it cools down from printing temperature to ambient temperature. Parts with higher infill density tend to warp more (the edges curl up).
But 20 % should be fine, you shouldn't have any issue at that percentage (unless you're ... |
Can I repair my microwave with a PLA part? | I would say PLA itself should not be heated up by microwave. It's because microwave oven creates oscilations which excites water particles (see microwave explanation here) so assuming PLA doesn't contain water, it won't heat up. (removed to not mislead as the water is not only material which heats up by microwaves. Tha... |
Supports for dense Voronoi pieces | One feature of Cura is the ability to set supports to build plate only.

How to edit G-code created in Cura to begin printing at a specified layer height? | Well this is a little complicated since nozzle height could collides with the part if the line 1169 has had started to be printed (part of the line), so the overlap will be the main problem, however adding the initial parameters to heat the extruder and getting the X0 and Y0 with G1 X0 y0 Z385 I recommend to increase Z... |

Problem in 3D printing of an empty model | You have modeled your bird. So far so good, but you likely only modeled a single surface and not a closed surface body.

To turn the bird into a printable object needs it not to be a sing... |
Should I enclose my 3D Printer? | It is hard to tell whether you personally should enclose your printer. However, you asked for the advantages and I will name some of them on which one can base a decision.

Sloped bridges in Cura | Cura has some options in this area that might or might not help. I've had mixed results.

Some procedures to improve 1st layer | You don't get a more accurate Z height when you heat the printer and let it settle. You get a different value that will work perfectly. E.g. I've got printers that do bed leveling cold but print with the correct initial Z height to get a perfect first layer. This is also valid for manually trammed beds. The only settli... |
Adventurer 3 3D Printer doesn't extrude correctly | There are a number of different ways to narrow down the problem.
Your printing temperature is likely too low. Raise it up about ten degrees, but don't try a print just yet.
Ensure that the Bowden tube is firmly pressed into the hot end assembly. A gap below the tube is asking for future problems. If the tube is clea... |
What to do with failed/unwanted 3D prints? | The "obvious" answer is re-grinding the prints and making more filament. Unfortunately, this isn't yet a very economical or simple operation. A decent filament extruder capable of holding acceptable diameter tolerances is around $1000, and even then they can be pretty fidgety to operate. You have to have a LOT of volum... |
Find OpenSCAD code from image | To my knowledge, OpenSCAD does not have any such feature. However, a related feature might help you: the debugging aid modifier characters. By inserting %, #, !, or * before an object (including aggregate objects), you can control how it renders in relation to the whole file; this makes it possible to do "binary search... |
Can snap-fit connector be designed for 3D Printing? | yes
You can totally print snap-fit connectors for 3D printing, but you need to keep some things in mind.

Repetier Host stops sending commands to printer when switching Windows user | Is it possible that in updating Repetier you inadvertently installed it for a single user rather than for everyone? If so, that might account for its stopping when the user is changed. |
PLA printings always ~0.22% larger | You are not taking into account die swell.
When printing with a 3D printer hot plastic is forced through a nozzle, which leads to the expansion of the material. The result is, that with 0.4 mm nozzle and 0.4 mm intended line width, the material will actually deposit some fraction of a millimeter wider. In your test ca... |

SLA printers: food-safe resin parts | Resin basics
Resins are tricky, but probably less tricky than FDM as the manufacturing process is much less likely to include contaminants in the shape of contaminated air, particles, or adding lead into the print.

Should you use hairspray on a metal bed 3D printer? | I have been using a sort of a very strong hairspray called 3DLAC for about 2 years directly onto the aluminium heat bed of the Anet A8 printer I have.
Basically, all those sprays contain copolymer constituents, PVA (PolyVinyl Alcohol), Vinyl or Acetate. These are also found in certain glue sticks or wood glues. For ... |
Are parentheses allowed within a G-code comment? | This is not universally valid G-code, and how it is handled depends on the implementation. You can use this style of comment on some machines, but not all.

Ender 3 distance between nozzle and bed changing on Y-axis | Your video shows that your bed seems warped somewhat.
Ammount of error
As I assume you did level the bed with a sheet of paper to be 0.1 mm thick, we can estimate the change of thickness. The thickest point seems to be 0.2 mm, the thinnest 0.05. that's in average an error of 0.075 mm for the first layer. If you can liv... |
First layer lines don't stick at all | This looks a bit like your build plate isn't level. I'd suggest re-leveling using feeler gauges. |

A page with a handful of Creality printers should appear including Ender 3. Tick the ... |
Is there a way to get more horizontal coverage out of "Vase Mode" in Simplify3D? | Version 4 allows you to have multi-process vase mode prints -- do the vertical surfaces in vase mode, then switch over to normal mode for the horizontals. This lets you have the best of both worlds in the same print. :) |
Makerbot Replicator 2X - restarts after heating | "Im guessing its the mightyboard or the power pack."
Right track there.
Usually this symptom suggests your heaters are overtaxing your power supplies.
Since you swapped extruders already, the heating elements and sensors in those are not likely to be an issue. That leaves the bed heating element and power supply.

Automatic bed leveling probes outside of bed despite NOZZLE_TO_PROBE_OFFSET | The problem is that, although you have set the offsets correctly, the boundary limits for the probe to "probe the area" have not been adjusted. It is my belief that this is a flaw in ABL of Marlin 2.0.x. If the user has set the probe offsets, the firmware already knows that the probe area is limited!

What causes ripples on part of first layer? | First layer rippling is usually caused by a too low of a first layer height (for the amount of extruded filament).
Are you sure that:
Your bed is leveled as good as possible, and
the initial height between the nozzle and the bed is correct when Z=0 (A4 paper thickness, when moved should be giving some drag), and

When dwelling G4, my printer is oozing, how can i stop that? | Ooze is virtually unstoppable. This becomes apparent once you understand why an nozzle oozes. As the filament melts, its viscosity drops and the free flowing filament slowly makes it way out of the nozzle due to the action of gravity (and sometimes thermal expansion). If you make the throat air tight then you can use a... |
Printing multiple prints stacked on top of each other | If you can get it to work reliably and with decent quality, it would be a good solution. However, you might find it unreliable and the bottom surfaces of the objects might not turn out very nice (as is usually the case with overhangs that needs support). How well this will work is strongly dependent on the object being... |

PID autotune fails 'Temp too high' with 12 V heater cartridge but works with 24 V? | It is all about resistance.
This requires some formulae:
$U = Voltage$
$I = Current$
$R = Resistance$
$P = Power$
$U = I \times R$
$P = U \times R$
$ R = \dfrac{P}{I^2} = \dfrac{U^2}{P} $

Through what methods and mechanisms can a multi-material FDM printer operate? | Let's look at various methods:
Multiple Hotends

Rough vertical ridges | Looks like under extrusion, here's a extreme example.
I would check your feed rate by marking out 100 mm on the filament then manually extruding 100 mm. You can use this to verify if you are under extruding due to your feeder. If you find that the printer only fed say 90 mm when you asked for 100 mm, you will need to ... |
How long can you leave filament in the extruder | Most filaments you can leave in the extruder indefinitely without any ill effects.
There are some filaments that need to be stored away from moisture, particularly Nylon, because they absorb moisture from the air and don't print well if they contain a lot of absorbed moisture. However, this isn't an inherent issue wit... |
Do hygroscopic filaments (PVA, Nylon) absorb moisture while in a heated enclosure | The concept that relative humidity decreases with an air temperature increase runs consistent with the concept of using a food dehydrator to purge moisture from filament spools. As the filament heats up, energy is imparted to the water molecules within. The dryer air around the spool will accept the moisture and "... |
Printing an iPhone Case | Yes this is possible. For an FDM/FFF printer, you'll need to print with supports. I might also recommend printing in PLA to minimize the chance of warping during the print (from experience).
It might also help to slow down the feedrate to ensure smooth surface finish and avoiding delamination on such small layers.

Small part bed adhesion | One technique is to add your own custom brims to the model. A couple of "Mickey Mouse ears", attached to each end of the piece, may be enough to keep it in place (and will also be easy to remove). |
First Layer problems? | As the filament in the melt chamber heats up, it's going to inevitably ooze a little bit.

Auto bed leveling with BL Touch sensor crashing to bed | As it turns out, my Z-axis carriage mount to the X-axis was bent, causing the nozzle to touch the bed before the proble could get a chance to detect anything. Manually bending it back to the correct angle solved the problem. |
Custom 3D printer printing dimensions has changed because of a .gcode file | Your printer is an Ultimaker clone or something else?

It is unclear if the resin is available now or if it is preorder. |
How to re-program Prusa firmware to accept a taller Z axis? | A .hex file is of no use to you, because it consists of compiled firmware which is very difficult to edit. You need to go to Prusa's GitHub and download the source code. Then, find the header file for your model of printer, and change Z_max_pos to the correct value. Finally, you need to compile and upload the firmware ... |
How to print LiDAR file format LAS | Because my research shows that LAS files are point cloud data, you would first have to convert the point cloud to a mesh. Point clouds are just that, data references to points in 3d space. A printing service works with files that represent planar surfaces, properly joined (watertight, aka manifold) to form a solid or s... |
Anet A8 extruder motor moves back and forth | Check the continuity of the wires on the cable. Sometimes, they are not crimped correctly. Another common fault is crossed wires. In either case, the easiest diagnostic test is to substitute another cable, but please note the color coding of this replacement wire to match the cable you replace. |
Is it possible to upgrade the CR10-S Pro to CR10-S Pro v2? | Print recovery can be achieved by changing the firmware.
Here is some information on how to do that: Marlin documentation
Also, this another stackoverflow post about that: Stackoverflow Post |
"Err: MAXTEMP: E1" when THERMAL_PROTECTION_HOTENDS is disabled | #define THERMAL_PROTECTION_HOTENDS is for thermal runaway. When the temperature "should" be climbing or falling at a predicable rate, or holding steady once at running temp.
#define HEATER_0_MAXTEMP defines the maximum temperature Marlin will allow the extruder to get to before initiating a shutdown. This is ... |
101Hero 3D Printer - Printed object is tilted | You appear to have a couple of issues here,
First off your nozzle appears to be a bit hot for your filament (you can see this be the drooping and sagginess of the layers on the outer shell)
Second issue is it appears as though your belts are loose. You can tell if your belts are loose if your parts seem to be shifte... |
When do I need to get a BLTouch upgrade? | A touch or an inductive or capacitive sensor are useful when you cannot get a completely level bed which can be caused by a skew bed platform/heated plate or if the plate has a bend, large concave or convex area.
Even with such a sensor, you need to provide a bed that is as level (trammed) as you can get. Automatic Be... |
Reprogram Marlin to assign endstop pins to arbitrary tasks [Arduino Mega] | Apparently, given one
has already enabled USE_<AXIS>_PLUG (for example
<AXIS> = XMIN) in Marlin's Configuration.h,
one can add an additional define (for example <AXIS>_ENDSTOP_CUSTOM) in
Configuration.h and
make this block the else statement in an
<AXIS>_ENDSTOP_CUSTOM existence check, with... |
