Well, the error popped up again today so the boss called the repairman. It sounds like he's putting in a whole new board, so we'll see what happens

That didn't fix it.

We're getting a second error every time it comes up with the motion control queue error, and it says something similar to "ATC Error, exchange arm at 0 degrees input not detected".

It's happening on the same tool (out of 3 tools in the program), always the 1/64" cutter, but never in the same spot in the pattern. This last time, it popped up with the error before it even started cutting with the 1/64", which should eliminate any heat and expansion problems. This thing is really starting to get annoying
