ANET A8 E3DV6 Titan Direct Drive X Carriage

cults3d

UPDATE V2 : modified fan_pipe V2, and added fan_pipe_holder V2 to get a stronger fanduct mount, using fan blower screws. Yet another X carrriage for Anet A8! This one was designed with the following features: - Direct drive compatibility with Titan extruder (a clone, but should work okay with the original) or E3D V6 hot end. - Nema stepper compatibility (using the original stepper provided with the A8). - 3Dtouch (a clone of BLtouch) compatibility. Its particularity is that it can use: - Original fan ducts or fan ducts designed to work with the original X carriage, like Mistral fan duct (https://www.thingiverse.com/thing:2121279). - Original X Belt holders/tensionners like this one (https://www.thingiverse.com/thing:2134573). This design also features: - Use of original Anet A8 bearing blocks or any remix if preferred. - Easy unmounting with only 3 accessible screws to remove the titan+ hotend + stepper block. Baseplate is a remix from scratch of this thing baseplate (https://www.thingiverse.com/thing:2193695). BLtouch Right mount is a remix of this thing (https://www.thingiverse.com/thing:2443459). Fan pipe attachment to the fan is a remix of this (v2.1a) (https://www.thingiverse.com/thing:2121279). Big thanks to the designers! Here's how it works: - Print the baseplate, the stepper&titan holder, the fan holder, and the fan pipe. - Check that the stepper&titan holder can mount okay inside the pocket of the baseplate. - Optionally, print a BLtouch mount. You've got the choice between left or right holder; I recommend right holder which is stronger. - If you don't have a belt holder/tensionner, print one. Recommendation: https://www.thingiverse.com/thing:2134573. - If you don't have the original fan duct or a compatible one, print one. Recommendation: https://www.thingiverse.com/thing:2121279. - Screw the BLtouch mount on the baseplate (M3 screw should be fine), and screw the Bltouch on the mount (use washers to adjust height if necessary). - Screw all the bearing blocks on the baseplate with the original screws, except 3 screws; the upper left screw on the upper left block, the upper right screw on the upper right block, and the upper left screw on the lower block. - Screw the belt tensionner behind the baseplate (use 2xM3 nuts in the 2 hexagonal prints in front of the baseplate, and M3 screws). - Mount the stepper and the titan extruder (with the V6 hotend) on the titan&stepper holder. When it's time to screw the last 3 longer screws to close the titan, use M3*35 screws and don't forget to mount the fan holder with these 3 screws (optionally use washers). - Screw the fan on the fan mount (with M3 screws + nuts + washers). - Screw the titan&stepper holder on the bearing blocks with the 3 last screws. Take care that the titan holder touches the bottom of the pocket in the baseplate before screwing, or you could damage the bearing blocks threaded holes. - Put the fan pipe in place, and the fanduct. If needed, you can use zip ties on each side of the base plate. - Do your cable management (you can use zip ties on each side of the base plate). - Modify the offset in the firmware. If you use Marlin, here are my parameters (please check your configuration; I will suppose that you have already your 3dtouch working. If not, please look for a tutorial): ```python define X_MIN_POS -5.6 define Y_MIN_POS -10 define Z_MIN_POS 0 define X_MAX_POS 220 define Y_MAX_POS 220 define Z_MAX_POS 240 # For the 3dtouch right mount: define X_PROBE_OFFSET_FROM_EXTRUDER 29 define Y_PROBE_OFFSET_FROM_EXTRUDER -2 define Z_PROBE_OFFSET_FROM_EXTRUDER 0 # For the 3dtouch left mount: define X_PROBE_OFFSET_FROM_EXTRUDER -32 define Y_PROBE_OFFSET_FROM_EXTRUDER 0 define Z_PROBE_OFFSET_FROM_EXTRUDER 0 ``` I won't give Probe Bed Position because it depends too much on how your bed is set up (glass, clips, ...). So please check manually that you don't probe too far on your bed to avoid damages.
