It should all even out over multiple moves. The commands to the step generator are absolute positions, so the input to the stepgen would be 1 degree, 2 degree, 3, degree etc, and you would see step deltas of 166. 167, 166 and so on. It is also unlikely to be a problem with the accuracy of the worm, that would be a cyclical not cumulative error. If you are absolutely sure that you you have the scaling correct then it might be that you are losing a microstep on reversals. perhaps take a look at your direction setup timing. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
