My Mk2 48x30 probably has had 15-ish hours on it and randomly just started carving the wrong place tonight. I took the guards off the sides and checked wheels and backlash nuts and they seem ‘ok’ but I’m not sure I know exactly what to look for. When I move the x rail back Y1 will sometimes get stuck, and sometimes y2 seems like it gets stuck. I’ve adjusted the eccentric nuts to make sure the wheels are all on the rails. Is there something else I’m missing?? It’s been working great for many months - not sure what’s up.
PK see my post from yesterday in machine support and cncjim reply. Not sure if your issue is the same but sounds similar
