How can I activate the 12VDC spindle output of the VEVOR S4040 engraving machine?
I have a smaller 12 VDC spindle of a Gemitsu PROver 3018 router that I would like to use for some jobs.
I made this S4040 12VDC spindle port available on the back of the control box and it measures approx. 11 volts when activated through the M03 g-Code command. However, when I connect the spindle it moves at very low RPMs. I measured the voltage with the 12VDC s
pindle connected and it is approx. 1 VDC.
Is there something else that need to be done to have this 12 Vdc port working properly?
Please advise.
