  1. Short answer: "Yes, for some it does". The results from your image are typically seen when the initial layer height for PETG is too small. PETG likes an additional gap on top of the usual that is used to print e.g. PLA.

  2. This is a known problem of the Anet A8 display, it is caused by electrical interference. Pressing the middle button will refresh the display. This is prone to happen when doing long prints.

  3. I finally found the problem. The threaded rod of the Z axis was not mounted tight enough to the motor. This resulted in the slipping of the Z axis by large accelerations of the motor. So...

  4. Here's a brief outline I threw out in chat once. I'm marking this as a "community Wiki" answer so feel free to edit. It is not a full Primer, so should date better than a Word6.0 manual.

  5. OK to begin with, you shouldn't be getting any movement of course and because there is some it indicates you have no glue joint and that some or all of the screws holes in the uprights are either stripped, or if pilot…

  6. It was a worn extruder gear. I didn’t think it was THAT worn, and when I loosened it a bit and slid it a few mm so that the gear hit the filament in a fresh spot it didn’t improve.

  7. I had this same issue and fixed it by removing the z-stop cable and using the black and white (the combined 2 wires on the BLTouch). Below is a diagram that may help.

  8. I'm answering my own question here. The Issue was that I set Z_MIN_POS to -2.0 I guess these 2 mm were subtracted from G28 but not from G29 .

  9. I think this is an issue with Marlin v2.1.2.2, which I was trying to use. https://github.com/MarlinFirmware/Marlin/issues/26809 this issue points to another bug with probing.

  10. This is classic Layer Shift in the Y plane. This happens in one of three cases: Belt too loose Belt too tight Bed movement hindered The belt should ring and resonate when tapped, giving a nice tune.

  11. I think I found an answer. When the gantry is low (Z less than 100 mm high) the Xmax (right hand) side of the gantry has some play, if I move the gantry higher the rollers tighten up.

  16. Successfully solved the problem. Removed the Z rod from its socket, and greased up the threaded slot it goes into on the x gantry, that seemed to solve the problem.

  17. Yes the Z offset needs to be redone each time a nozzle is removed even if you re install the same size. Another thing to verify is to ensure the slicer is actually set with a 0.4mm nozzle

  20. It's all but confirmed that the printer was defective. I got a new printer and loaded up the sample G-code it comes with, but the bed's belt snapped 10 minutes into the print (it was only finger-tight).
