I have been building a Kossel Rev B. After a lot of tinkering and a few new parts I finally have the thing connecting, sensors working and motors responding. However, the motor response is much larger than expected moving cm instead of mm when using Repetier host (maybe that is how it should be). More importantly:
-The motors do not respond immediately while homing, instead there is a high wine for a few seconds
-When moving down it will occasionally not move on one of the towers leaving the printing head uncentered.
-they do not stop when the zmin induction sensor is triggered.
What I have done:
-Checked the code and make sure I haven't changed anything weird
-Tried a different manual operation software (pronter face)
-Ensured everything was wired as indicated
Any insight would be appreciated.
