Does MPG A-axis = A-axis in UCCNC?

[crjohnson]

Hi all,
Hopefully this is an easy one: I have the A-axis in UCCNC slaved to Y (dual ballscrews etc) and am building a 4th axis for my machine. I also use a WHB-04B-4 mpg pendant (works great!), but when I wire up the 4th axis, will the A-axis on the MPG only correspond to the A-axis in UCCNC?

Will I have to change the 2nd ballscrew/stepper motor to the B or C axis in UCCNC?
Cheers,
Craig

Yes, A axis is A axis in the UCCNC.
You have to slave the Y to B or C if you want to use the A axis as 4th axis.
