Denford Triac VMC with ATC Conversion / Fix

Ok. clearly not although it uses switches called datum, that is what is confusing. The Triac usermanual confirms the same - home is correct as I have it now.

Can anyone explain why, when the CS Labs unit has a fault condition, my machine basically drives both X and Y to the positions furtherest from home? How do I stop this from happening?

Also, spindle relay wired, connected to output 6 on the CS Labs digital output but spindle doesnt run. I try M3 and M4, I can see Mach 3 flashing that there is activation, but the actual relay (24V out on output 6) doesnt kick in.

Actually, I think I know why in the first instance. I need to get enable to work via the controller. Currently the DER (Drive Enable Relay - which cuts power to the drives), is hardwired as its 0V 'on'. That said, why is something controlling it (ie, giving it reference to move), when there is a fault? Some type of failsafe?
