First yes I have called Optronics on this and they are not sure what exactlly could be causing my problem

After I have been running one of my edgers most of the day I start having probe errors.
I get the message that the probe tips have fallen off.
After pulling the job back down and probing first it "usually" probes and cuts it just fine.

Optronics has given my several things to check for. I am just checking to see if anyone else has had a similar problem. My voltage is fine, but one of the driver chips does feel to be much hotter then the others. I have swapped the driver chips around to see if that takes care of the problem but the same slot gets hot not the same driver chip.

any help would be much appreciated
