Re: Servo as a Spindle - Mariss?

I like Jon's idea about a separate pulse generator feeding directly
into the G320 as a spindle control.

What are the speed limitations of the drive with a 500 ppm encoder
servo?

Would you have to isolate the PC from the spindle pulse train
somehow? Or just have two sets of inputs at the step/dir pins on the
drive?

Could the frequency generator be some inexpensive programmable chip?

I am using Mach1 (soon to be Mach2 hopefully) are there any spindle
controls being implemented by Art?

Jon, keep those ideas comming
