V-Minion Y-axis slipping
Howdy,
My V-Minion's Y axis is slipping if I push acceleration anywhere north of 5k mm/s^2. I really don't know what could be causing this. I am using a BTT SKR2 with TMC2209 stepper drivers and the stock V-Minion LDO steppers. I tried putting it on top of a 35lb concrete paver and making sure the steppers were configured for active cooling. Any help would be greatly appreciated.

Here's something resembling a benchy attempted ~30k mm/s^2. As you can see, the X axis had barely any issues if at all, while the Y axis was all over the place.
Ok so theres definitely something SEVERELY wrong with this printer, I have pretty much no issue pushing around the Y axis when its supposed to be locked in place
update: pretty sure that was an unrelated issue with the pully not being tightened. issue still happened before I loosened the pulley and forgot to tighten it though
Are you running the drivers in stealthchop mode? I solved the issue when turing back to spreadcycle mode.

I dont think so, but let me check
Running
grep -r spreadCycle . yields no results, but the line for enabling stealchop in printer.cfg is commented outspreadCycle is the default I believe. Stealthchop is not part of the problem you are having if it is commented out.
