Hi, and welcome!
Please add a note to this list of UK owners: Any UK MPCNC owners?
The problem with a walk-through is that there are so many ways to use these boards, any document (like the instructions) end up with complex options that someone building a basic MPCNC doesn’t need (like end stops, a laser, heated bed, etc)
If you’re just doing a standard machine, it’s actually pretty simple.
- Apply 12v power to the power socket. Be careful of the polarity or it’ll blow a fuse.
- Remove the power and plug in your LCD (if it doesn’t work, try switching/reversing the plugs. There are only 4 combinations, and you won’t damage the LCD by plugging it backwards)
- Remove the power and plug in the stepper motors, before attaching any belts. Use the LCD to check they all move the right direction, and flip the plug to reverse if necessary.
Always disconnect the power when changing board connections .
If you’re using Ryan’s stepper motor wires, it should just work. If you’re making your own, the instructions show you how to wire them.
If you’re using a RAMPS board, there are a few more steps in the instructions (and it doesn’t have a fuse, so getting the input polarity wrong is more spectacular)
The standard instructions are pretty much what you’re asking for, you just have to know which bits you can ignore!
Have you bought any electronics yet?
