Hi all,
I have 5 identical stepper motors, and 3 red mach3 boards (2 different sellers, "white eagle", 4 axes).

I notice an identical behavior with the 3 boards:
. the 5 motors turn well in 2 directions on the 4 axes
. the X-axis (speed set to 50 %) with the 3 boards, makes the 5 motors turn in both directions 4 times slower than the Y, Z, A axes (speed also set to 50%)

Could someone enlighten me??
