Defining X and Y coordinates of multiple Z steppers
-
Hey guys. I'm setting up 3 independent steppers on my Z axis to be used as automatic bed tramming steppers. In the documentation it says to define the X and Y coordinated of my steppers. One of my steppers is past the origin (0,0) of the machine. Do I give this stepper a negative value, such as (250,-25) or do I have to offset the origin? Thanks in advance.

Yes, you need to give negative coordinates see the wiki:
