Secondary Independent Z-Axis

Hi,

I'm brand new to LinuxCNC, and this forum, so apologies if I'm in the wrong category but I didn't see an existing post with this topic.

My controller is setup to run 5 axes (X, Y1, Y2, Z, & A), but the A motor defaults to a rotary axis. Is there an easy way to change that to linear? And once that's done, my gcode would just need to reference "Z" for my Z1 motor and "A" for Z2?

Working from home today so I can't share hal or ini, thanks in advance!

You may Configure your Machine as X Y Z W machine?
W is linear and can be controlled by gcode.

Thanks for the reply Norbert.

I'd like to avoid reconfiguring as someone had modified the hal file (pretty sure) to allow access to other relays inside the controller (probotix unity 2 fyi). Is it easy to manually change the "A" axis to W?
