Hi, I got my Mini Mill up and running last night. I have used your Black Box and after following the you tube electral build all worked as demonstrated in the video. I have just gone to do my first job and I cannot get the machine to work. It refuses to home, I have restarted my computer, restarted Control, I have reset the g code, all to no avail. I keep getting 'Homing fail, could not find limit switch within the search distance.', see screenshot. I have checked the limit switches in the troubleshooting section and all trigger, all connections are sound, but, I have noticed that I can turn the jog wheels easily with the machine powered on.
