Relay on at start up
« on: February 14, 2023, 04:03:47 PM »
I have a pokeys57cnc board and you must first turn on that machine before loading Mach4.  My coolant relay automatically is activated when I start the machine and then when Mach4 finally loads Mach4 turns it off.  How do I get it to not turn on automatically?

TIA

You get mach to enable a relay that switches the main power on the machine.

Maybe I'm misunderstanding you Graham.  I can't have Mach4 run a relay without a board and mach wont connect to the pokeys board unless it is already powered.

Pokeys turns on a relay that turns on the machine main power pokeys can be powered by a small psu of its own.
