Hi everyone, I hope you're all doing well!

I'm building a 4-axis (XYZA) CNC machine for fabric cutting. I haven't yet decided which software I'll use, but from what I've seen in videos online, Mach3 seems to meet my needs well.

I need to control the A-axis (4th axis) as a tangential knife.

Could someone show me how this configuration is done in Mach3?
