I've been plagued with an issue for about 6 months now and it's getting worse.
2006 PRT Alpha with HSD 4HP Spindle 1PH
Dell Latitude notebook (830 I believe) with W7 not online.
Symptom:
This has only occurred while hot, i.e. the machine has been up and running at least an hour or so, not a continuous job but multiple 20-30 minutes jobs. In a job the machine will stop and the spindle will shutdown. The bot is locked in place as if sitting idle. The PC, meanwhile, is still running the job as if nothing has happened. To get it working again I have to close the software, powercycle the bot itself and run the software again. Then it works until the next event. If I don't close the software and just shutdown the machine I get a lost comm error which is basically what you would expect if you turned off the machine before the software is closed.
Work so far:
I have replaced the relays, the USB dongle, the USB cable, the USB hub, cleaned the PC and checked it out (it's offline, hasn't had an update applied in years) I have checked every connector twice.
Suggestions so far are
1) ground the machine to prevent static build up. Well... it's grounded but heck, I'll pull everything out and re-wire it with a new sub-panel if need be.
2) replace the notebook that's been running it for 5+ years. Obviously "easier" than option 1, I'll try this first.
Other ideas? Advice? Hints?
