Question about RAMPS wiring
January 06, 2012 08:35PM
So I here's my problem guys: I was soldering my RAMPS 1.4 board and accidentally butchered the Z axis part of the circuit. Basically I soldered the wrong header and had to take it out, lifting one of the traces right off the PCB in the process. Short answer the Z axis doesn't work. Now there are spots for two stepper drivers, but I only need the one. Is there a way for me to remap the pins in sprinter so the Z axis is mapped to the second extruder?

Also, I tried using some silicon paste to attach the heat sinks to the pololu drivers and I can't get it to cure. Any ideas?

Thanks guys,

That should be a simple change in the firmware. According to the schematic, the E1 Enable, Dir and Step pins are D30, D34 and D36. Plug those values into the RAMPS 1.3 section of pins.h.
