Running M2 Nano
Using firmware that came with it.
I had a heck of a time getting my new K40 to home correctly. To make a long story short, I replaced the optical end stops with mechanicals and that solved the problem and it seems to be fine now.
The conversion was easy and I was able to remove the flat ribbon cable and wire each stepper and the end stops directly to the board. On the M2 Nano, there is a 5 pin connector that handles the X and Y end stop signals. The C3D board has the same type of connector and it looks like that’s where I should plug in the end stops. But I’m not sure which pins are which. There should be a gnd and signal for each of the X and Y and them an NC pin which isn’t used. Here are pics of my M2 Nan0, the wiring diagram that I used to connect the end stops to it, and the CD3D board.
If the pins are different on the C3D, it’s no big deal to swap them to the correct location in the plug. I just need to know where to put them. Thanks for any input, I’m getting ready to do the C3D upgrade and it’s gonna be nice to be able to use Lifghtburn!
