No I have not. I did try a new cable set with no effect. New stepper drivers are on the way and will try those out if that does not work new board then.

What board did you order? There are several different ones to choose from. I am leaning to a GT2560.

Thanks for keeping this thread going!

not yet see above

still working on it! What motherboard did you order?

I did try for a response and zero replies

Just a ramps and arduino combo, trying to move away from these Melzi boards. Last time I tried this type of board, in fact it literally was this, I think I fried something. I can’t even count how many times I went through and double checked the wiring, when I plugged it in my PC connected to it, controlled it for a bit then smoke came up from it.
