Print the mount in whatever material and color you want. I used Hatchbox Black PLA @ 50% infill and 3 perimeters/shells and 3 top/bottom layers. I used Simplify3D to do the slicing @ .15mm layer thickness and printed with support. The best results will come with the motor face part down against the bed. It took about 2 hours to print on a Prusa i3 @ 40mm/sec.
To wire up the motor to the original UM2 board I cut off the original extruder motor wires about 75mm from the board connector. I added my own connector in case I wanted to put the original back on again. <div><br></div><div>Wire it up like this: </div><div><br></div><div>UM2 --------------------------- Bulldog XL </div><div><br></div><div>Black -------------------------- Brown </div><div><br></div><div>Green ------------------------- Red </div><div><br></div><div>Red ---------------------------- Yellow </div><div><br></div><div>Blue --------------------------- Blue </div><div><br></div><div><br></div><div> You will need to change the steps/mm for the extruder to 495. You can do this by downloading the latest version of Tinkergnome firmware here: <a rel="nofollow" target="_blank" href="https://github.com/TinkerGnome/Ultimaker2Marlin/releases">https://github.com/TinkerGnome/Ultimaker2Marlin/releases</a>
Open up Cura and goto Machine->Install Custom Firmware and select the TinkerGnome firmware .HEX you downloaded.
Then on the UM2, Advanced->Preferences->Motion Settings->Axis Steps/mm and change the value for E to 495.</div><div><br></div><div>-</div><div><br></div><div>-EDIT: Forgot to add the support bracket for the planetary. </div><div><br></div><div>-Take the extruder apart, remove the black spacer and replace with this one. </div><div><br></div><div>-Now it will have the proper support on the back end of the motor assembly.<br></div>
