I am placing my stepper drivers on the SKR Pro board. The instructions say correctly that only 5 are needed but the placement of them is not discussed. I assume it matters where they are placed. Do all 5 go together on the side toward the JST terminals? Or do they split 3-2?
In close inspection, it looks like the 5 controllers will go in the first 5 slots and the last one will remain open which appears to coincide with port E2. The more I look at it, the more I think I’m correct but can someone confirm for me?
That is correct. The E2 driver can be left unpopulated.
X = X1
Y = Y1
Z = Z
E0 = X2
E1 = Y2
Note that there are 2 motor sockets for Z, and the second one (as shown) has jumpers on it to short the 2 pairs of wires. This js necessary as the sockets are wired in series, and ot having the jumpers means you will get no power to the Z motor.
