note

The stepper position toolbar might turn red for the following reasons:

1. External stop is active.(All axes show red)
2. Home switch is pressed.  

note

If an axis does not move when homing is triggered, inversion of the polarity of the ref IOs might help.

A homing procedure consists of 2 parts: 1 move on the switch with refspeed and 2 leave the switch with refspeed2, which is usually much slower than refspeed. If the polarity of the reference IO is incorrect, part 2 of the homing process is executed at first. No movement is done because the switch is already left. To invert polarity of ref IOs, please see refvalue.
