Tuesday my shopbot started cutting sloppy and I found out one of the x-axis step motors wasn't working. Swapped the 2 x-axis gecko controllers and the other quit working. Swapped them back and they both started working. Today after cutting a carving that took over an hour, I changed bits for 5 minutes of flat clearance cutting and it stopped working again (cut sloppy). I powered the shopbot controller off and on and it started working again. Monday I am ordering a spare gecko drive or two - does that sound like what the problem is? Do they sometimes get flakey before they quit working or could I have a bad connection somewhere?
One small sign I made on tuesday had an interesting hand made look. Had me stumped for a bit - couldn't figure out what would all of the sudden cause the machine to loose precision but still basically cut what it was supposed to.

Bruce,

What is the temperature of the Geckos? They will shut off if they get too hot. Try leaving the control box cover open or off and then use a 20" or larger room fan to blow on the control box.

Thanks Mike. I will try that.
