You have some problem with the home switch being detected. Home state 5 means the joint is moving, and the homing code is waiting for the switch to close. > Note: I tried monitoring the axis.0.home-sw-in with Halmeter, but it > never changes.

If they are ever different, you have a problem (since the two pins are supposed to be connected together, they should always have the same value). You should be able to hit the switch and see all three halmeters switch between true and false. - Steve ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
