Uh, OK... turns out there's something wrong with the file - it doesn't shove off a loose layer, it actually shifts the printing position

"Fucking how!?" is obviously my first question, but also, it looks fine in the Prusa gcode viewer & how is THAT possible...? 🤯

@jwcph Did you watch it do the thing? Does it actually print on the side or does it "pick up" the layer somehow and push it over?

[jwcph@helvede.net]

@balu Well, you can actually see in the video that it's printing off to the side - the layer wasn't just pushed...

[m4x@chaos.social]

@jwcph @balu Did you check the typical causes of layer shifts? Loose belts, warped corner the nozzle catches, stepper motor current too low,. .. I bet there's a suitable article in Prusas docs / wiki

@jwcph @3dprinting I've read it sometimes does stuff like that if the usb has been corrupted in a weird way that is very common with the one prusa give you. If you haven't already maybe try a new one?

[jwcph@helvede.net]

@M4x @balu No - I'm pretty sure the file is corrupted so my first attempt to fix is to re-do it from scratch

[beeb@hachyderm.io]

@jwcph @3dprinting if you suspect it's the file, you should be able to re-download it from the printer and compare it with the original. However, a loose belt or bad motor is more likely to be the culprit IMO

[jwcph@helvede.net]

@beeb @3dprinting I agree; it would usually be more likely - but this is not a usual situation, apparently (the preview on the printer screen also looked weird, although not in a way that reflects the flaw) & the new file currently running on the printer looks much better so far
