Hello all,
I have recently purchased an used UM2, which has a weird issue with very slow XY moves.
It appears that the movement is not continuous, but stops at certain intervals.
This is also causing a kinda zebra effect on surfaces.
I wrote a test g-code file for demonstrating the problem. It's got only one move, G0 F50 Y100.
A video with very audible movement sound is here.
Any suggestions would be very welcome.
Thanks!
