If the DC motor has a smaller spindle it will feel more difficult to stall. You can actually apply quite a lot of torque on a 20mm shaft by hand. If you have a small torque wrench you can try calibrating your fingers :-) The only thing that can really be wrong is the initial homing to the Hall transition. Are you sure that you have the correct pattern selected? (have you tried straight "h" mode, and all the patterns ?) -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
