Hi, First post here, I hope someone can help. I’ve been getting some good prints on PLA using Kiri:Moto, so thanks to the developer.
Wanted to do some printing in ASA for outdoor, UV exposure.
First prints had warping and adhesion issues, built enclosure and started using a little acetone ASA mixture as a bed coating. That aspect now looking solved.
New problem, print repeatedly failing in same place.
Prints fine up to 2.6mm height, then I hear a thump and y has skipped by a few mm, abort part.
This keeps happening in same place, always 2.6mm
Do a bit of googling, suspect Zhop, set that to zero, similar failure.
Difficult to capture on camera, but I’ve seen it, at beginning of new layer, nozzle plunges into the print, with the nozzle anchored in the print when x or y tries to move it obviously then skips steps
Suspect something wrong with my stl
Print 20x20 calibration cube instead, same result
I allow the cube to finish, for the most part it prints fine, but occasionally it does that plunge and skip thing, finished print has shifts in both x and y axis.
It seems the stepper driver and mechanical setup is OK, I can make them skip by hand, but it requires a pretty substantial force.
Printer: Sovol SV01 (using creality 10S as most similar printer, I know this seems off, but Ive been getting some nice prints in xABSx edit: PLA up til now)
Material: ASA Basic (Using ABS settings with tweaked nozzle and bed temperature)
Unfortunately I cannot upload gcode file as a new user. But I’ll post settings:

So here is it telling the z to go to Z0.6714 when we are already at 1.6mm layer height? Is that normal behaviour?
Thanks in advance for any help, I’d like to keep using Kiri:Moto if I can, I hope I can get over this problem somehow.
