i have noticed that the led on the relay lights up but dim and does not click in when the spindle is switched on in mach 3
the relay works 100% if i wire it direct to the power supply it clicks in and closes the contacts.
the relay is wired direct to the +24v on the power supply and the ov ground from the power sully goes to crd on the novusun...the out1 from the s axis goes to the relay for the OV
