E3D v6 hot-end mod for Da Vinci 1.0

thingiverse

This is a remix of thing:608560, which works quite well but in my opinnion it could do with a more sturdy assembly, for improved stability of the hot-end and the carriage itself. I've modified the lower part and the spacer (which comes from the original v2 design). The upper part and the drilling template are the same models that can be found in the original v1 mod. Update (20150512): I've created a custom layer cooling fan duct to go with this mod: http://www.thingiverse.com/thing:822476 Instructions Bill of materials: E3Dv6 1.75mm Universal (Direct or Bowden), or the new Lite6 version. 2 x 30mm M3 screws (35mm would also work, I think) and optionally a few washers. You want the upper and lower parts to be as sturdy as possible, so don't be cheap with the infill, use 50% or higher. Use the drilling template to drill the holes in the carriage that allow raising the stepper. This will require removing the X carriage, for which you'll also need to detach the left Y carriage from its rod (just pull from it to detach the bronze bushings). Then unscrew the stepper motor from the carriage, place the drilling template lined up with the existing holes and drill the 3 missing ones. Finally, use a utility knife or something similar to make a semi-circular cut into the plastic of the carriage, as shown in the picture of thing:608560. This is required for the stepper to fit on its new position. To reduce the friction at the pivot of the metal bracket that holds the idler wheel, I suggest you add a washer like on my picture (I just super-glued it to the plastic). Assemble everything back tightly and make sure the stepper's gear is well lined up with the throat of the E3D. Depending on your printer's accuracy you might need to sand or shim the lower part for this. The short PTFE tube going down to the gear that you can see in the pictures is optional but highly recommended to facilitate the loading of filament. To install this I used a solder iron to soften and widen the tube and then applied super-glue. The breakout PCB board may be attached in different ways. Mine is simply zip tied for now but I'm working on another piece to do this better. Update (20150405): A little while ago I designed a custom holder for the breakout PCB, which is nicer than having it just zip tied. I've uploaded the model, which could be easily extended to even make use of the filament sensor, should anyone ever want to do that. However, as of today I've just gotten rid of this PCB -since it's not actually necessary- and made straight connections for the fan and the thermistor using quick release connectors. See the pictures with and without it. Read the volvivo thread below (page 4) to find out the wire mapping (warning: the 1.0 and the 1.0A use different wires and/or colors for each thing!)
