CR-6 SE Direct Drive Mount Remix [Added v4 03.21.2021]

thingiverse

This is a (far, far from elegant, but functional) hacked, slashed, chopped, screwed, mashed-up, and remixed version of konton's CR-6 SE Direct Drive Mount v2 (https://www.thingiverse.com/thing:4701896), which incorporates this (https://www.thingiverse.com/thing:4681847) to allow for the use of this extruder (https://www.biqu.equipment/collections/j-head-extruder/products/dobule-pulley-mk8-extruder-dual-pneumatic-joint-extruder-kit-for-creality-cr-10s-cr10s-pro-ender-3-ender-3pro-ender-5?variant=31554886697058). I also merged elements from this (https://www.thingiverse.com/thing:4761065) and this (https://www.thingiverse.com/thing:4764095) to add cable management. I imagine other clones of this general extruder design can be used. The salient detail is that the sensor is raised by 7.5mm to maintain alignment with the extruder. Requisite Hardware: (4) m3 hex nuts or nylon lock nuts (2) m3 6mm button head screws (2) m3 8mm button head screws (2) m3 35mm flat head screws (1) Braided 600mm extruder motor and filament sensor cable (https://www.etsy.com/listing/958625306/custom-braided-creality-cr-6-direct) [Alternatively, you could extend the existing cables or replace them with longer cables. Just beware if you replace the cables you will probably have to switch the outside wires on the sensor and inside wires on the motor. So unless you're comfortable splicing or unseating and reseating such wires I'd recommend the above linked item as it is plug-and-play; plus it's tidy] Some additional notes: (1) as can be seen in one of the pictures the smaller text I embossed on the side of the "branded" version is illegible, not that anyone would want to make that version anyway, lol; (2) the extruder and hotend are misaligned by around 0.5mm along the y-axis (motor mount would need to be moved back), but this does not seem to impair functionality; (3) as can be seen in some of the pictures the breakout board does not mount flush because the clearance I used was insufficient (should have broke out the calipers instead of guessing based on faulty memories), but, again, this does not seem to impair functionality; and (4) the below print settings are obviously aggressive and need not be adhered. Cheers! Edit [03.13.2021]: Had a filament jam (unrelated to the mod) so I rebuilt things today and took note of the ptfe tube length; it's 91mm. I also implemented a couple of hacky fixes until I make a proper v4: (1) I added 1.5mm shims above and below the breakout board's screws between the board and mount; and (2) I filed the five holes on the motor mount to allow for it to be mounted 0.5mm down [there's an addition flaw in konton's design I never mentioned wherein the stepper motor does not mount flush with the horizontal plane; it sits ~0.5mm above it's intended platform] and 0.5mm back. Furthermore, it should be noted I noticed another flaw in my design, the extruder arm pushes up a little on the runout sensor. This does not seem to effect functionality. The solution would be move the sensor mount up ~2mm. Edit [03.21.2021]: Uploaded v4, which fixes or, at least, minimizes the previously mentioned design flaws and one recently found/unmentioned flaw in the alignment of the runout sensor. It should be noted the senor is now raised by ~9.5mm and there is one hardware change. The (2) m3 8mm button head screws need to be replaced with 10mm screws to mount the breakout board. I also made a new version (v4_nut) wherein I merged a m6 nut in to runout senor riser to allow for the use of a pneumatic connector/bowden coupler, which would require a PC4-M6 or PC4-M6-C fitting.
