Title: Random twitches after crash
Post by: james elder on October 28, 2012, 10:24:09 AM

Hi All.
After a dive into the bed, the z axis twiches randomly. (the stepper is out of the machine, so it isn't something slipping).
Is a short dive enough to ruin my stepper, or is there some other error or setting I should be looking for now.
I believe the crash was caused by my asking it to go faster than it normally does. (300%. It isn't recommended I know).
Look forward to any replies.
Jim

What do you mean by "twitches"?

Given a down arrow, or an up arrow, the spindle randomly ticks from side to side, tries to go one way, buzzes, tries to go the other, buzzes, tries every 1 or 2 seconds: Bbbrrr Brrrr Brrr Bbbrrrr.
Dro is correct of course.
However. I have now tried swapping the Gecko's, to eliminate them at least, or see if the problem followed the Gecko, and it didn't . The problem seems to have gone.
Any ideas what happened?

Bad motor connections likely.
