First, let's get your physics straight: To make it moderately shock-resistant it's placed on a 50x50 cm concrete tile which is placed on 3 mm of foam. The foam reduces vibrations being redirected to the tile while the tile is heavy enough not to care either way. No. The concrete tile gives your printer mass by adding its own to it. Mass by itself results ...

I have had similar issues, and I have learned three tricks: Some slicers (i.e. Cura) let you specify the height of your first layer, and I have found that slowly incrementing up from 0.16 mm by 0.2 mm to find the sweet spot of adhesion without warping. Every brand/type is different. But, usually, for me, fall between 0.18-0.22 mm. Blue painters tape. If ...

Turns out this is the behaviour of files that get corrupted. This has very little to do with the slicer and everything with how some SD cards are just intent on getting themselves a bad name. In this case, the file was corrupted enough not to be readable on the machine that put the data on there. If the file can't be opened and made look readable by a normal ...

Am I doing something wrong? Did I destroy the "Carborundum" coating (silicon carbide) of the glass plate? I doubt it. Silicon carbide is tough stuff: it's a 9.5 on the Mohs hardness scale, just half a notch below diamond. They make router bits and end mills and the teeth of table saw blades out of it, and people clean all of those with much ...

It is likely the surface was damaged by the chemical cleaning, based on your description and octopus8's comment. If you are unable to mechanically release the print, there is a chemical method that has worked for me (and at least one other SE user) in the past. Bring the bed up to about 40 °C and turn off the heat to the bed. Apply with a dropper or swab a ...

Whenever the UI of a CR-6 doesn't function correctly after a firmware upgrade, either the firmware upgrade didn't go well or the firmware of the screen is no longer compatible with the firmware of the printer. If you know the screen and firmware are supposed to be compatible, try updating the firmware again. There is some sort of 'is this update the same as ...

You cannot change the Vref of a UART operated stepper driver, setting the current directly is the way to go on UART operated stepper drivers; in fact that is actually what you are doing on non-UART operated stepper drivers, you change the Vref to change the current through the stepper motor, the higher the voltage the higher the current through the stepper ...

Seeing the infill from the outside is usually caused by having a thin wall or an incorrect wall thickness compared to your nozzle. Wall thickness should be a multiple of your nozzle diameter; so a .4 mm nozzle should have 0.4, 0.8, 1.2 mm thicknesses. The following list of solutions is from All3DP's article "Troubleshooting Common 3D Printing Problems&...

If you need it to hold the thermistor in place, there are thermally conductive electrically insulating potting compounds, such as Appli-Thane® 7300 Urethane that have a temperature range of -100 to 160 °C. The newest CPU thermal pastes contain silver particles and will conduct electricity. So, it needs to stay away from leads and pads that don't want to be ...
