Direct drive assembly for Titan or equivalent extruder using the stock Anycubic carriage plate. I used the TriGorilla here which I believe is what comes stock on the Mega S. There are many Titan clones available which I do not have experience with and cannot recommend. You can also go with the original E3D Titan which is really the righteous thing to do.
The Titan works with the E3D V6 or equivalent hotend. I used the Trianglelab version here.
The part cooler is a slight remix of https://www.thingiverse.com/thing:2815388 which is a remix of https://www.thingiverse.com/thing:2765158.
The belt holder is a remix of https://www.thingiverse.com/thing:2838383 made to mount directly to the i3 Mega carriage plate.
Design uses the standard micro fan that comes with the V6 hotend mounted facing forward on the heatsink.
- 2 x M3 14mm
- 2 x M3 8mm
- 2 x M3 18mm
- 6 x M3 nuts
- 1 x M4 22mm and M4 nut for fan
- PCB board reuses the 3 stock M3 screws.
- GT-2 6mm belt (stock belt is too short by about 30mm)
- 1 x 5015 radial fan like this one
- 1 x Short body Nema 17 stepper motor like this one which works great because of it's low weight
When printing the part cooler, make sure supports are only used on the outside of the part and not the inside which will likely happen when auto generating supports (S3D will do this).
A primary objective of this design was to retain the same printable area as stock, but you will need to modify your "Home" offset for the Y axis approximately 10mm to accommodate the new nozzle location. This can easily be done in the EEPROM using the M206 or the M428 commands.
There have been lots of requests for a BL Touch to be added. Feel free to remix and please leave a comment if you do improve on this design.
