Makerbot Dual Extruder
So I am on the home stretch of my dual extruder upgrade. I ran into a few small snags. I forgot to order an extra extruder controller (duh) Luckily Dr. Glass of Freeside Atlanta was able to loan me one till I get mine from Makerbot. There was also only one e-stop port on the motherboard so I had to hack a cable to plug the 2 safety relays into it. Then I realized that I didn't have enough molex connectors so I had to cut off one of the sata power plugs and rewire it as an old school molex connector. SOOO I'm finally done with the hardware and wiring. Now I just need to tweak my REF values on the stepper controllers for the new extruders and install the new software.( Which means teaching myself github finally and compiling the latest experimental build for Rep G and maybe doing the same for the firmware too) This is going to be a treat because I am also forcing myself to learn how to use PLA at the same time so adventures are soon to abound...
