AndyUK's Build - 1.2x1.0m Gantry

Yeah that thought did trouble me too...

I didn't notice the drive working when I wasn't overriding the safety circuit, but it's also possible that in that condition the UB1 won't send the step signals.

I need to dig up some example circuit diagrams where people are switching the enable lines of the AM882 or EM806.

I use EM806 and I switch the enable line. Offhand, though, I can't remember exactly how, but I think it's a direct connection from a relay contact on my safety relay. Too late tonight but I'll try to sort out some info tomorrow. I know that my EM806 are in the default "disconnect to enable" mode as I've never tried to reprogramme them.
