SKR Pro Stepper Inputs Question

CABix · January 30, 2021, 7:04pm

This strictly a question that I am curious about?
following the V1 Control advice:

Stepper Motor SKR Pro Driver Connection

  X1                                         E0
  Y1                                          Y
   Z                                          Z
  X2                                          X
  Y2                                         E1

Question: Why does X1 plug into E0 versus X, and X2 plugs into X?
It works great but just wondering.

Thanks…

It does not. It should be:

X1 → X
Y1 → Y
Z → Z
X2 → E0
Y2 → E1

Where did you get your table?

I made the table from the V1 Control instructions. It is working.

Your X1 and X2 are probably swapped. But it doesn’t really matter, as long as your endstops are switched as well. I will fix the docs.

Omg with the serious help you provide to “more serious” problems I feel bad I asked.

This is meaningless as I said it’s working.

Thanks…
