E3D Chimera Hotend Adaptor for CraftBot

thingiverse

I've decided to try out the new E3D Chimera hotend on my CraftBot 3D printer. This is still a work in progress, but test prints of Sitting Fox by PHYSICS_DUDE (http://www.thingiverse.com/thing:166984) and Aria The Dragon by loubie (http://www.thingiverse.com/thing:600550) have seemed to print well. Update 2017-01-26: I've switched to using Bart's custom E3D all metal hotend, which has been working great for quite some time. https://craftunique.com/forums/view-thread/1434 Instructions Please note that this is a work in progress. This is an adapter to hold an E3D Chimera hotend on a CraftBot 3D printer. I have a Chimera dual hotend and also an E3D-V6 hotend. Since the heat sink of a Chimera hotend fits more easily on the CraftBot, I've decided to try it out. It's using only half of the Chimera dual hotend, and I'm hoping that I can use both in the future with a CraftBot upgrade. Update: I've cut out the right corner of the adapter so it doesn't get blocked by the fan screw hole. New R4 file uploaded. Parts Needed: 1) Print out the STL file in ABS. 2) M6 nozzle throat.

Instructions: 1) Print out the STL file in ABS. 2) Enlarge the thermistor hole in the Chimera heating block by drilling, so it can accept a stock CraftBot thermistor. 3) Cut the M6 nozzle throat in the section where there's no thread. 4) Heat up the nozzle throat. I heated the nozzle throat on my gas stove. Be careful; it gets very hot. 5) Slowly insert the nozzle throat (the cut end) into the printed adapter (the left opening with the heat sink fin facing you). Make sure it stands straight up. When it's good, let it cool. 6) Insert the PTFE tube into the (already assembled hotend) Chimera heat sink. Cut the PTFE tube with a sharp knife flush with the top of the heat sink. 7) Attach the adapter (with nozzle throat already inserted) to the top of the heat sink. Screw in the 3 screws. 8) Insert the Chimera hotend into the CraftBot hotend holder. 9) Screw the nut on the M6 nozzle throat to hold the hotend. Don't tighten yet. 10) Place the stock CraftBot fans back and insert them between the hotend holder and the nozzle throat. Adjust the position to make sure that the hotend is sitting firmly, then tighten the M6 nut and also the fan holder screws. 11) Connect the hotend heating cartridge and thermistor on the heat block. 12) Calibrate your heat bed platform. Do a preliminary test print. Congratulations! You're done! Please feel free to provide your suggestions/feedbacks or modify it as you see fit.
