Hi guys working on wiring up my build right now. I recently bought a MPCNC that came with the mini rambo board 1.3a.
Right now I have the negative and positive wires plugged into the terminal block and that is plugged into section B for motors, logic, heaters, fans.
At this point, I am supposed to be seeing a solid green LED light near the USB port showing power but I do not see any light what so ever.
I have checked for voltage from the power supply and that is reflecting 6 going into the terminal blocks. I have also checked the fuses F2 and F3 for continuity and that is also good.
Anybody have any ideas?
Just some additional info:
I had the board connected to my computer, power, motors and LCD at one point but was not receiving any power. So took several steps back and decided to just test for power. If I would move the Core around the workspace while all was connected by hand manually, I would see the GREEN LED light flicker but it would not stay on and has not ever stayed on consistently.
edit: If it helps when I connect USB to PC, my computer recognizes the board and I hear it connect.
