This page is to select the stepper motor control pins. Because Stepper motor control pins address are fixed by
the controller board, So here only need to define the Pin address(No.s),we can define other parameters meter.
To make sure the Z axis to the right direction(Up is '+',down is '-'), Z axis's "Dir low" should be set to"√".Oth-
er axes's should be set as the user's request.
Second, make sure that you have your home switches assigned correctly (Menu -> Config -> Ports & Pins ->
Input Signals). While you could use a single input for your X, Y, Z, and A homes, it is much better to have them
as separate inputs! Our EC500 controller has plenty of inputs available and it allows Mach to home all of your
axes at the same time if you wish (although you typically have your Z axis home after the rest of your axes so
you don't crash your head).
