I have a stepper powered 4th axis (shown in the show and tell section) that I am considering converting to servo power so that it can be used on the mill as a pseudo lathe.
Currently I have a 10:1 reduction and a 10,000 RPM DC motor to use which would net a max 1,000 RPM which is adequate for my purpose. I can install the encoder wither on the motor or on the belt drive idler.
First, I wonder if anyone is doing something similar and if it is considered viable.
Second, if I put a 200 step encoder on the motor, there would be a max of 2,000,000 pulses per minute. What kernel speed would be needed for that and in general what is the relationship between the encoder steps and kernel speed?
