Hello from Russia. Gathered according to your drawings CNC. Filled your firmware . Can’t run the extruder. He’s heating up. But the stepper motor does not twist. Rearranged and the engine and 8825 on the X-axis it works. Please tell me where to find the fault.December 17, 2017 at 7:26 am #49632
The extruder needs to be hot to extrude. The firmware has safety checks to avoid cold extrusion. I don’t know what the limit is, but if you heat it to 190C then it should extrude at that temperature.December 17, 2017 at 8:09 am #49636

What commands are you using to try to move it?
I can’t think of another reason it could be a software issue. If you swapped the motor and 8825, then it must be a problem with the ramps or Arduino.
You could swap the pins of X and E0 in the firmware (pins_Ramps.h). Then test like that. If that moves X (which is connected to the E0) then it’s something in the software or your command. If it doesn’t, then it’s something broken in the Arduino or the ramps board.
