2 in 1 out mixing nozzle having trouble getting set up in repetier server
I am still fairly new to 3d printing and just got my second printer... a Geeetech A20M. It prints in both colors and mixes find when printing from SD card but when I set up in Repetier server, and slice with software using the correct method for doing 2 color prints, I can't get the second extruder to work. In repetier server when I set up it only detects 1 extruder... do I need to add the second extruder? That seems to be the only way I can get control of the second extruder and manually extrude material to clear either extruder. Any assistance in setting this up properly would be appreciated.
