On the last four small projects, I've had the machine stop with the "close cover, press enter" on the display. This occurred several times during each project (every 1-5 minutes out of the 30 run time). On the last project, after several stops/restarts using "enter", I got a "Z-axis stall, error 246". I turned CC off, then on (Z-axiz stall cleared), went to project and found that the door sensor again indicates open (although physically closed). Recycled machine again. Under Option/(7) Sensor Check, saw "Cover Switch: open". With cover open, I used small dowels to depress both L and R switches; still "door open".
Emailed CarveWright; awaiting response. Any other ideas??
