I have a blackbox and am having trouble using the home button on the open builds control software. I have x and y motors installed and functioning (I can jog them), along with the respective limit switches. I also am using the z stepper motor, however it is not being used in the traditional sense of a vertical z-axis. Instead it is being used to rotate a small spool of fabric, therefore it doesn't have a limit switch. I believe that when I hit the home all button the system first runs the z motor trying to find its limit switch. Once it fails to find one, it stops and shows an error. Is there a way to only home the x and y axis?
