First off - This is my first question, I’ve been learning a lot from these forums over the years so thanks!
I’ve been using my X-Carve since 2015 (1000mm model with Arduino controller).
Recently my cuts end up with irregular shapes. I’ve attached a circle cut to demonstrate. The odd thing is that it seems very intentional - even with almost no load on the machine (0.1mm depth) I get the same consistent irregularities, and they reappear in exactly the same form with every depth pass / every new cut. Even when I redo the cut at a different position I get the same irregularity again (see 2 circle attempts in the attached photo).
After browsing the forums - I tried checking the machine alignment, straps tensions, wheels, current limiters, reflashed the arduino with latest GRBL version, tried using both EASEL and other software. Seems consistent.
Any tips/ideas would be much appreciated!
