Welcome to the SeeMeCNC Community

So, I came home today and noticed that the print I had running had gone italian. It was very confusing, because when I inspected the print, which was 6 separate pieces, 2 of them had spaghetti, and one looked like the nozzle had dive bombed into it, while 3 were fine. I was quite confused. So when I started my printer up again, and homed it, I hear what sounds like a stalled motor and the z-tower not moving. Oh. Shit. I check the belts, everything is fine, and I pull the belt off that tower, home again, still hearing a stalled motor. So I pull the LCD panel and switch the y and z tower. Now it's the y tower making the noise. Shit. So, it appears I have a fucked up stepper driver. So, is there anything you guys recommend I try before I send the board back?

So, being somewhat intoxicated, and using all my brain cells that are still working, I realized that the Rambo has 5 stepper drivers and I'm only using 4 of them. Yay dual extrusion! So I cobbled together a fix. I modified the pins.h file, and switched the E1 step pin, dir pin, ms1 pin, ms2 pin with the z equivalents. Success, right? No dice. Hmmm... So I kept looking through the files, since the answer had to be there. Success! Found it. You also have to modify the #define DIGIPOT_CHANNELS to {4,5,1,0,3} instead of {4,5,3,0,1} and then it will work.
