I don't think the encoder is bad-it's a basic, non-intelligent 8192 incremental encoder with three channels. The machine worked, but was reporting position errors.
I'll check the motor out and do a little testing, but I'll be looking for an AMC or Granite Devices drive-the Granite Argon series claims to directly support this type of encoder and shows a hookup method, so if it will do PWM/Dir or Step/Dir, and is able to index the spindle for the BT30 spindle keys, then that's all it's got to do.
Thanks for your help, MacTech
