Z axis homing issue on new ALLIN1DC <resolved>

[thelinuxman]

I replaced an old M15 console with a new ALLIN1DC and I am having an issue I can't seem to solve with the Z axis.

All axis limits are wired and working. Z jogs up and down fine. I am homing "Z" in the positive direction to the Z+ limit switch (Input 6).
-IF I have Input 6 as +Limit & Home+ input it should ignore the limit during homing, but if I home... I get a Z+ limit tripped alarm.
-IF I remove Input 6 as a +Limit & only have it as Home+ Input and home... Z trips the switch but never backs off and I get "Switch failed to clear"

Also of note- I cannot jog Z in the opposite direction if a limit is made like I can with X & Y.

I can home X and Y and they work as expected. They trip the switch and back off. I can also jog them + if the - limit is made and - if the + is made.

You have direction reversal on for that axis which means that the input wires must be swapped physically and the input numbers reversed as well.

Simple enough, thank you!
I reversed that axis obviously because it was going the wrong direction. I never considered I would have to swap wires and switches since I believed + meant + and - meant - and they appeared correct when tripped.
Thanks again

On the Allin1DC, INP1 - INP6 are not just PLC inputs; they are also directional current inhibits for the DC servo amplifier section.

Because of that, the Z axis output will not apply positive-direction current if INP6 is open, regardless of what your CNC12 software may say.

That is why you also have to swap switch inputs when you change Direction Reversal.

That makes sense, thanks for the explanation.
