Could I make use of expansion plug pins for my XY and Z?
So useE2 for my X
Use E3 for my Y
And use E4 for my Z.
Yes, use the M584 command in config.g to specify which drivers your axis motors use.
Do you think I may have a problem with one pin feeding signal to upto4 drivers?
You might be able to drive 4 drivers from one expansion breakout board output. Or you could use E4 and E5 to drive 2 Z drivers each.
