content: Fitting this went remarkably smoothly (for me).I will need to print a new case to replace the one I printed for the original board, apart from that, in Marlin mode, everything works fine.In Touch screen mode, its getting some info from the main board, but for other things, it still thinks it's an Ender 3.The touch screen config.ini file statesCode:# In order the TFT firmware is able to provide all of its functionalities/features,# ensure that the following options are enabled in Marlin firmware.## General options:# EEPROM_SETTINGS (in Configuration.h)# BABYSTEPPING (in Configuration_adv.h)# AUTO_REPORT_TEMPERATURES (in Configuration_adv.h)# AUTO_REPORT_POSITION (in Configuration_adv.h)# M115_GEOMETRY_REPORT (in Configuration_adv.h)# M114_DETAIL (in Configuration_adv.h)# REPORT_FAN_CHANGE (in Configuration_adv.h)andCode:#### Machine Size / Build Area# The TFT will auto-detect the machine size (min and max) in Marlin firmware (requires enabling `M115_GEOMETRY_REPORT`# in Configuration_adv.h in Marlin firmware).# Format: [size_min: X<minimum distance> Y<minimum distance> Z<minimum distance>]# [size_max: X<maximum distance> Y<maximum distance> Z<maximum distance>]# Unit: [distance in mm]# Value range: [min: -2000, max: 2000]Hmm, as I type this, I think I might know whats wrong, while M115_GEOMETRY_REPORT is enabled in Configuration_adv.h, the bed size is set is in Config.h only.I always presumed it got all it's info about things like travel speed, bed size etc from the main board, looking at the touch screen config.ini file, it looks like I might have to specify a lot of it again.Oh well. not a huge deal, at least I've not had any bed leveling problems in a year lol

content: Why does the TFT have to know bed size though?At least for mine I'd just move it until it hit a software endstop, then it reads back the position and shows its unchanged.But addmittedly I went back to regular Marlin TFT, I had too many issues with it hanging or being slow to respond to inputs.

content: I noticed it because while testing the touch screen, I found the 4 corner levelling buttons.Only the front left was correct, the other 3 were the corners of an ender 3 bed, not a CR10.I fixed it by adding the bed size to config.ini and reflashing the touch screen firmware.

I can understand doing a follow-on with tie-ins to the original, but a remake of a film full of 1970s elements in the 2010's?

content: I imagine those would not be pleasant to walk on. Like squidgy sand, will strain the leg muscles, and probably terrible for people in high heels.I also wonder if that makes them liable as a trip hazard. I noticed my local area is recently getting all the bumps in the footpaths (aka sidewalks) ground down to ensure no trip hazards. These are usually caused by tree roots shifting the concrete slabs over time.

author: RJSV

timestamp: August 21, 2025, 10:50:32 pm
content: Haha; I have terrible risk of falling, in the very situations just mentioned. A sidewalk up only 3/4 inch, from the previous slab, generated an emergency room visit (minor facial cuts).'STENOSIS' of the spine.That disorder causes a deficit in the usual, normal electrical impulses, to the legs, while walking. The sort-of lazy style of walking by not picking up feet high enough is what leads to the hazard: I trip on as little as 1/2 inch (2 cm). Easy enough, for an EE to comprehend: simple signal blocks, from the brain's electrical output, down the spine.Medical system, BTW, straight players often comment, that the surgery solution, tagged as 'Lumbar Relief' is an often used, harmless (major) procedure, used for chronic back pain. A major surgical procedure, that involves pulling out the spine, and then putting it back (in).I couldn't make up a worse sarcastic tale, than this truth.

timestamp: June 05, 2025, 05:41:17 pm
content: I bet it's just the frontend ordering the events in the order they arrive from the server (via async JS; they load these event lists after the page itself), rather than sorting them and displaying them in order of timestamp, either native JavaScript real number seconds since Unix epoch, or ISO 8601. Most programmers just do not grok asynchronicity or message reordering, and assume that since the order is always correct in their local test system, it must be so on the internet also or it's user's fault. Hell, they cannot even be bothered to check if operations failed or not (return values, error codes), "because that can be added in later on when we have more time".The next step, I wager, is your friendly AI-based server hallucinating the package delivery events, so you don't even know whether the events actually occurred, or are just shown to you because the server doesn't want you to be disappointed.

There are lots of clones of these small buck converters, many based on original designs by TI.The only way to check if they are fake is to order some and see if they work at all.Even clones are not always identical due to cost cutting or poor reverse engineering, so they can work at first but turn out to be problematic in the future (early failure, poor specs between batches, EMI issues).

content: I just purchased a new hair clipper set for the dog.On delivery the charger would not work, so I took it apart and a number of components had corroded to the point that wires were eaten completely through.My first thought was a capacitor had leaked but they all looked OK.I did not investigate any further as I am sending it back.Looks like rust from water immersion.The clippers were also rated at 400 watts at 12 volts the battery consisted of three 18650 cells in series so I have no idea where 400 watts came from as at 12 volts that's 33.33 amps.

Most battery operated tools are rated like this. A peak power for the tough jobs, and a typical average battery life with a mixed range of work.

There are no claims about power consumption. I haven't been able to see any pictures of the enormous power cables that must be necessary to drive this thing. Also the noise must be insanely high due to the high number of cubic meters of air you have to send though this device to get the water you need.Besides the point: There are better and cheaper ways to get water during a RAIN storm. St. Petersburg recorded nearly 18 inches of rain, marking a 1-in-1,000 year rainfall event.

The pictures that I HAVE seen all show lines of tanker trucks lined up at the Tampa area hospitals to provide them with water. And not just the hospitals, there are tanker trucks all over central Florida dispensing water to anyone that wants it including at a city park about four miles from my house. On top of everything else, I can guarantee you that any place that doesn't have water commercially available due to the storm certainly doesn't have commercial power available to run such a device.This is just another SCAMMER looking to take advantage of people after the storm.

The cards are essentially identical hardware-wise, but <=32GB capacity are considered SDHC and >32GB are SDXC. Some dumb, inflexible or pedantic devices (like cameras) actually refuse to use a card if it has "wrong" filesystem on it, even if such device supports the same filesystem on other cards.I agree that this error comes from FAT32 limitations. Fake cards advertise fake capacity and simply discard old data when they run out of actual storage, you only notice it when you try to read your files back and find them corrupted.
