Good morning all, I just started building a cnc router and ran into an issue with my software , using CNC USB Controller v. 2.10.1204.201, I can't figure out how to set a slave on my Y axis, I can create 3 axis with a forth slave but that doesn't work. I have a UCNCV4 controller FMD2740C drivers(4) and 4 23HS2430B stepper motors. In the initial stage so not installed on the machine yet.

Any help would be great.
