I got some problems with the Jog function.
It is not generating step pulses.
It seams like the pwm generator is not runing / working.
Moving with G-code is working fine.
I got it nearly working, I had to change the
m.dutyAtRun = (2^m.bits)
in Jog_v3 to
m.dutyAtRun = (2^(m.bits-1)),
but now it skips some steps.
