NOTE: Anything I claim to understand in this post could absolutely be incorrect, please bare with me!
I've been hired to set up an Okuma Cadet Lathe and I'm simply trying to achieve max travel on the Z Axis before I move forward but I'm having trouble. I understand the general concept of how these machines work and have limited experience with programming. We seem to have gotten enough travel out of the X Axis but the Z Axis is proving to be more difficult.
Now, I understand that System Parameters (+/- Stroke End Limits) are the outer limits before hitting hard limit switches, but when we move on to setting User Parameters I'm having difficulty with "what's what".
My question is this: What is the difference between "+/- Variable Limit (Prog)" and "+/- Variable Limit (Mach)"? And how do they relate to the System Parameters?
Also, side question: Seeing as these machines use pulse motors, how do the values in the "Actual Position" screen translate to Imperial Units?

Thanks in advance!
