My dad has built a CNC machine with a Mk3 board, he has a Spindle which he has wired to an output board following the instructions on the blog images of wiring at this link: https://imgur.com/a/4qpkEuH
I have enable the 0-10v and control by terminals in the programs and setup the cnc as attached picture shows.
The M3 command does nothing and the controls dont work either, what are we doing wrong?
