Mod XYZ Da Vinci to use Pico hot end

thingiverse

After upgrading Repetier firmware, I wanted to modify my Da Vinci printer to accommodate printing with filament types beyond ABS. The parts listed here enable the mounting of a B3 Pico Hot End, allowing for ABS, PLA, NinjaFlex, and PTEG printing. These custom parts were created by remixing an E3D mod; the original STLs required adjustments to fit the groove mount on the pico. The pico end can be obtained from here: https://www.youtube.com/watch?v=vX9r4Ncr4dU. Opt for the groove mount version. As of 26 MAY 2015, I have shared images demonstrating samples printed with ABS, PLA, Laywood, and Bridge Nylon. All worked within their respective temperature ranges with ease. So far, Fila-flex has proven temperamental, while printing ABS with Carbon fiber required a larger diameter nozzle opening; it is currently en route. Instructions for modification: Familiarize yourself with the Da Vinci printer's breakdown by watching these video series. Be aware that E3D parts are unnecessary since the Pico end is pre-assembled and ready for use. New screws were purchased to replace the original due to their M3 x10, M3 x12, and M3 x35 dimensions; additional M3 nuts (4 for fan) will also be needed. Remove existing components, following disassembly as instructed in the video series. A wobbly condition may occur; a Filaflex gasket can be printed post-modification to alleviate this issue. To reassemble the PCB, remove its spring clip and mount the new one upside down (note: initial picture depicts inverted setup). Align the filament sensor with the feed tube and secure using zip strips. Refrain from drilling holes in the PCB board. Fan modification: Re-attach the existing 5V fan to draw air out across the Pico, positioning it where it's clipped on the existing location. This will keep it under firmware control while mounted. Flex setup: Insert a short piece of PTFE tubing into the cold side of the pico; this should fit snugly. The PTFE tubing can be then guided to aid the Flex filament in reaching the extruder nozzle. Please see photos: printed in white for better visibility, however earlier pictures depict blue PCB clips and original form factors. Uncluttered wires will make their debut shortly as I removed plastic wraps; results thus far are satisfying! If you have questions or need further assistance, do not hesitate to ask.
