I’m building my first hobby CNC and could use some help with grounding my stepper motor and limit switch cables.
I’m using shielded cable for stepper motors and limit switches, but I am clueless on where to attach the drain wires.
The build videos for my CNC (CNC4Newbie New Carve) use a Demon Controller, which has a ground screw. However I have an Openbuilds Blackbox controller, which doesn’t appear to have a ground point to attach the drain wires.
The only ground point that I know of is on my Huanyang VFD, which is where I will be attaching the drain wire for the spindle cable. Should I attach the stepper and limit switch drain cable to the VFD ground as well, or is there a better place?
Thanks in advance for the help!
