I was cutting as usual today, then upgraded to the newest version 3.6.2. After the upgrade I would set home as earlier and the spindle would not find home after setting the coordinates. I tried more times than I should have and it would always go to the wrong spot. Remember I am cutting the exact same file. I let it cut even when at the wrong "home" and it would cut but at a much smaller radius as the original file cut with the earlier version. I reloaded the earlier version, removing the update and the spindle cut perfect! I have a PRSAlpha. Any help out there?
