Welcome to the SeeMeCNC Community

I've just built a Rostock Max V2. The heaters and the extruder motor appear to work, but the other three motors don't even attempt to turn.

Things I've tried:
- Repeatedly turning it off and on again.
- Moving it via every method I could think of (the movement and homing buttons in Pronterface, the LCD menus, manually typing G0 lines into the console, telekinesis). None of these worked.
- Flipping one of the motor connectors.
- Swapping one of the axis motors with the extruder. The axis motor turns; the extruder motor doesn't. I'd think this was a bad stepper driver, but 3 of them on the same board?
- The endstops are all reported low by M119 and change to high when I press them manually.

I also had to replace the included 450W power supply with a 350W one borrowed from my old printer, because the included one wouldn't power on. I don't think that's it, though, since one of the motors does work (also, I don't know the power requirements of those motors but I'm pretty sure it's not >350W each).

I have the "different" motor connectors mentioned on page 194 of the assembly guide, in case that's relevant.

Suggest other things to try?

Never mind, fixed.

For anyone who shows up here searching: I compiled the firmware with Arduino 1.5 instead of 1.0. Not sure why that fixed it, but it did. (Not mixing up the Y and Z axes made it work even better.)

I am glad that you got it fixed. Telling us the solution helps everyone, thanks!
