I am seeing this on one of my axis, after upgrading from 2.5 to master. It moves to the home switch, turns around to find the encoder index pulse, and after it finds the index, it faults with a following error - this only happens when I start Linuxcnc, ie when machine home isn't known. If I home all again, it works fine. This only happens on my regular axis, the other 2 are gantry pairs, which don't fault. I had FF1 set and command-deriv unconnected and it faults. Setting all FF settings to 0 still faults. If I connect the encoder velocity (from 5i20) to command-deriv - it faults when I jog - the velocity coming out of the pin is very noisy. Is this the same problem? _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
