Thank you. I am sure this will be a big help. Did you ever get your spindle drive figured out or did you replace it?

I had fixed it, it had some input voltage sensing issue.
I did change all the drives to Granite Devices Argon.

Did you keep the Yaskawa servos? I was told by many that none of the drives would work with these servos. I was gonna replace them with Dyn4 servos and drives. Maybe this would be a better way since the Yaskawa servos use a tapered shaft and the Dyn4 are straight. Means I have to make a coupler.

Thank you tommylight! Really curious if you were able to reuse the Yaskawa servos with the Granite Devices Argon drives?

No you can not use them as they have proprietary encoders, so changing the encoders was a pita!
