I'm still running Mach 2 as my laptop doesn't have the capacity for Mach 3. That being said, what I have done is substituted the A axis for the Y axis in my code simply by doing a search & replace with a text editor. I believe I can accomplish the same in Mach by slaving an axis but haven't read the manual on that. Anyway, the problem I'm faced with is the mechanical difference between the A axis and the XY axis's results in a substancial feed feed rate difference. I need to determine a way to make the actual feed rate the same for the A axis as it is for the others. Suggestions?
