stepgen.maxaccel was linked to the AXIS_* MAX_ACCELERATION value...
Now ive set stepgen.maxaccel to 0 and the ferror does not change if i apply different values to traj maxaccel...
i mean that change of acceleration does not effect the ferror any more...
Think that it is neccesary to run the stepgen maxaccel really high in velocity mode in combination with a PID - position control...
