SmoothStepper USB / Re: Strange behavior

Hello again,
Some of you may wonder, that if the only difference is the cable connected to the driver of the z axis
what happens if I remove it and revert to the initial configuration. Strange behavior shows again! Even if in Mach Z axis is
now disabled.
So, to recapitulate,
- x (port 1, pins 2,3) and y (port 1, pins 4, 5) connected alone -> motors loose steps and make awful noise if axes go in the positive direction simultaneously.
- Connect also z (port1, pins 6, 7), nice, clean, and smooth movement in all directions
All the checks mentioned before been taken into account.
I can't help but wondering what's going on
Problem seems fixed now, but It would be great to understand what is happening.
