Need help changing axis home direction? was created by Quarter20
I have a gantry router that utilizes the Y and Y tandem configuration. When I go to home it, my Z moves towards the positive direction instead of toward my home switch. Also my X and Y's are doing the same thing? Im sure this is a matter of changing some + or - signals in the files somewhere? Can anyone help?

I had this router working with Mach 3 and just swapped the Breakout board and LinuxPC.
The paraport wiring is the same and I put it into the step config the same way. I can jog the Z and X just fine, but since it is tandem Y, and that axis is last to home, I haven't gotten that far.
I just thought I would focus on the Z for now and get it to home upwards instead of down.
In Mach 3 I had put it set to home X and Y in negative direction. Z in Positive since it went from 0 to -150mm.
Any help is greatly appreciated!

How did you create the config?
If using the wizard, there is "invert" on the right side of every pin, so check that for direction of the axis you need.
You can also edit the .ini file and add " - " (minus sign) in front of the SCALE value for the joints/axis you need to change direction.
