My spindle count on the A axis also, so I was hoping that I could change the letter to U and make it display the RPM so I can see better. I want to keep A axis free to add a rotary 4th axis later.
Its still not clear.


This is what I'm confused about when determining my Factor in the c-code; if my encoder count/rev = 10000.
Would determining the Factor in my C-code be (#define FACTOR (10000/60.0) //10000 counts/sec / 10000 counts/rev = 1 RPS = 60 RPM)?
yes
