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,
Nigel
