any success?
Yes, at last, i reset those two parameters again and enabled it and it sprang into life
- If had rebooted yesterday it would probably have done it then too.
So, moving on.....
Pid Tuning
Of course, CS Labs in their infinite wisdom have removed the Auto-Tune from the spindle servo page
I have been plugging numbers for an hour now and although it runs its not happy. It will overshoot then slowly crawl back to dead-band stop, or it will run ok at lower speeds (<1500) but at 3000 it will e-pid fault on max following error accumulator being massive (>100000)
I've had it jumping about so violently i had to e-stop
and had it sit there slowly moving back and forth but never stopping.
Any ideas how to pid tune a spindle so it can run at 3000 and stop when told?
Getting there but no champagne yet
