I have recently purchased an HG08 breakout board which connects to a U300 motion controller to run my newly built Ox cnc. I am a woodworker and a little embarrased as my electrical knowledge is pathetic compared to a lot of you on here, hence my asking for help. The HG08 breakout board supports 5 axis, I have 4 nema stepper motors to connect to the board each of which has 4 wires, red, green, yellow, blue. On the breakout board each stepper motor input has GND, VCC, CKA-D, CWC, ENA-D. I do not have a clue what wire does what on the stepper motor nor do I know what goes to where on the breakout board. I know you can connect a voltage meter to the stepper motor or connect and pair stepper motor wires to check resistance but that still does not help me detemine where each wire goes as I do not understand CKA etc abbreviations on the breakout board. If someone knows what wire goes to what that would be a massive help. Also, on the controller boards I have seen there is a clone drive for the second Y axis stepper, presumerably on this it just goes into one of the spare A or B inputs as there is no clone?. Cheers in advance.
