So I can't really figure out what's causing this to happen, but it's happened on a few prints now, including right off the bat on a short, 10 minute print. Any ideas? I thought perhaps it was due to overheating, but the immediate skewing seems to discount that. I noticed the grub screws were a bit loose on the motor gears so I tightened those up and am reprinting the small part. Seems to be ok this time.

My guess would be the grub screw on the gears.

Then possibly the current is set too high and the driver goes into protection mode.

After that I would try turning the travel speed down. For the belt replacement of the gears I find 120mm/s is about the max for reliable with my under powered used motors.

Hi Maik,
I'm starting to notice this on some of my prints as well. Were you able to resolve this?

I had this on mine and it was a combo of the drive train slipping and the stepper drivers over-heating in summer as I was driving them of 19V.

I have had this a couple of times over the last couple of days. The first time was two separate step shifts in the X-axis on the same print. I turned up the current on the stapper drive slightly and that sorted the problem. The other time was a consistent skewing of the same axis. I traced this to a loosening of the grub screws on the large gears. Hope this helps.

Mine was due to loosening grub screws as well.
