I have one of those cheap CNC 3020 engravers. I would like to add my own Arduino controller but still have the option of keeping the old controller. Are these typical connectors used on CNC controllers? Anyone know what they are called?

Looks like I found them

You should also find them listed as microphone connectors.
They're called microphone connectors and were used on a number of different CNC controllers back in the day.
