For my first build I'm using an SPST 48V 30A relay (see photo 1) with a Gecko G540, and 48V 7.3A power supply. Without the stepper motors connected, I'm trying to get the relay to turn on the router but all it does is click upon reaching the "switch on" g-code in Mach3 and clicks again when I press stop. Not using a VFD or anything, just need to turn the router on & off. I tried using a ohmeter/voltmeter on the relay's output to the router and it's showing nothing when "clicked on." Photo 2 is how I have it connected. I'm using 14 gauge for all 4 wires. On Mach3 I've got the Spindle setup for Output #1, Port #1, Pin #17 and "Disable Spindle Relays" unchecked. What else could I try?
Thanks
