Re: [CAD_CAM_EDM_DRO] Servo issue

Jon and all,

Heres what I did. First swapped other motors on the same g320's which worked
fine, so Im assuming that it is the motor only.

It spins freely with nothig connected but when I connected the terminals as
you said it felt smooth and consistent for whole rotations clockwise, but
when anti clockwise I can feel a very light cogging, it does not however get
easy in one part or the rotation.

I did this same test on another motor and it was smooth both ways.

I also tested the motor at 90deg intervals with no change in its anti
clockwise weakness!

If this motor has a high number of windings could this cogging when turning
be an open winding? But would I feel this in only one direction?

The main thing is could this be the cause of my x axis going crazy? Or could
it have been my crazy x axis that drove itself into the stops and overheated
the motor?

Could I be getting noise or something from the computer, this worries me
cause all has worked fine for six months and nothing has changed except that
I overheated the motor but still which came first the chicken or the egg?

I hope this makes some sort of sense to you?

Thanks for all of your help.

Regards,

Jason Cox.
