Z axis wiring...



Table wired up...



The timer on the bottom rail is an off-delay of about 20 seconds for my downdraught fan, every cut start and stop triggers the Aux BOB relay and the delay holds the fan on between positioning cycles etc. At the end of the last cut it runs on for the full delay to clear any remaining fumes.

Preliminary panel wiring...



I've got an old BOB laying around and spare PC which i've installed a basic Mach3 setup on, hopefully be able to get the lot tied together this week for motion testing.
