Weird Pattern on straight lines

Dear Community,

I hope you can help me with my "problem". I rebuild my MK2.5s and now im noticing this weird pattern on my prints where there are supposed to be straight lines (see the benchys hull). I printed it on the standard MK2.5s PrusaSlicer Profile with Extrudr PLA NX2.

I thought it could be a problem with the extruder gear, but im not sure. And before disassembling it i would love to hear your suggestions. Could it also be a too used nozzle?

What do you think could cause the pattern? Or has someone experienced the same?

Best Answer by Dominik:

So i troubleshooted everything and found the reason: As i converted to TMC2209 drivers the Vref value of the Y-Axis Motor was way of (set to nearly 2 V instead of 0.86 V). This meant many vibrations and a motor that was getting way too hot (but it still works, i was surprised by that. After adjusting the Voltage it now works perfectly again. Maybe this helps someone having a similiar problem 🙂
