Art,
By turning on debug I assume you mean check the print messages box. When I do so, I get the following messages for a ref all command:
Axis 2 Estop capability disabled for homing
Axis Homing begins on Axis 2
Axis 2 Homed with 0 steps decel after switch
Homing Complete on slave motor 0
Homing Complete on Axis 2
All Homing Complete
Axis 0 Estop capability re-enabled after homing
Axis 0 Estop capability disabled for homing
Axis Homing begins on Axis 0
Axis Homing begins on Axis 1
Axis 0 Homed with 2177 steps decel after switch
Homing Complete on slave motor 0
Homing Complete on Axis 0
Axis 1 Homed with 0 steps decel after switch
Homing Complete on slave motor 0
Homing Complete on Axis 1
All Homing Complete
Axis 0 Estop capability re-enabled after homing
None of the axes move, none of the DROs change, the DRO status lights change to green. The home switch and limit functions show up properly in both Darwin pinout and M4 diagnostic screens.
Since I don't have a slave axis and I do have separate home switches for each axis separate from the limit switches and they are not set up to trip estop, I'm thinking this is an M4 problem, not Darwin.
BTW, after checking the print box in Darwin diagnostics, the previous problem with the encoders returned. I have disabled them until the feature is useable.
Hope you had a great Halloween.
