I need help figuring out how I should wire my K40s laser PSU to a Blackbox. I am new to the build your own world of CNC and I am not sure how to do this correctly and do not want to fry anything by wiring it wrong. I have added a pic of a quick sketch of the old wiring setup when the PSU was in my K40. I mainly just want to know where the wires that went to the m2 nano board need to go on the Blackbox. Thanks.
