The coil is reporting around 600ohms with my voltmeter but the battery is about dead so I'm not sure how accurate it is atm. No other isolated outputs are being used on the AXBB at the minute. I have proximity switches on the isolated inputs and a cheap 5 axis Bob for the control panel wiring. I'm wondering if I could use the 5 axis bobs relay as a charge pump to control the safety relay...i can assign it in uccnc but I think I read it can only be used by powering the 5v off usb rather than the boards 5v input.
