Geeetech A10m XCR3D 2in1out hot end mount

thingiverse

**Update** I have uploaded the Marlin 2.0.1 firmware that I am currently using for my XCR3D hot end to work properly. To make this happen, I had to flash the firmware because the OEM heating block was overheating and causing issues with temperature control. The new heating block is half the size of the original one, which led to a significant increase in heat-up time and overshooting temperatures. After reducing the maximum current setting from 255 to 75, I performed a temperature PID calibration and updated the firmware with the new numbers. I am offering this firmware as-is, so be sure to review it carefully before flashing it on your printer. This firmware is specifically designed for use with a BLtouch probe and 9-point auto bed leveling. This bracket allows you to mount an XCR3D 2-in-1 out switching hot end to your Geeetech A10M printer. Note that this will disable color mixing unless you use the mixing hot end linked at the bottom of this post. At present, I prefer printing clean colors over dealing with frequent nozzle clogs from the OEM hot end. The bracket mounts to the new hot end using four 3mm screws. I reused one of the OEM heat break fans for the new hot end. The new hot end and bracket then mount inside the OEM shroud using four 3mm screws that pass through the part cooling fan. I have included pictures and will answer any questions you may have about this setup. Please be aware that you will need to make a slight adjustment to your Z-axis offset to get the bed level again, as I tried to position the new nozzle as close as possible to the OEM one. The new hot end requires a shorter heating element. To achieve this, I plan to use a spare E3D V6 heating element from another machine. Additionally, it does not come with a new temperature sensor, so you will need to continue using your OEM one. Here is the hot end that I am currently installing: https://www.aliexpress.com/item/4000141586106.html?spm=a2g0o.productlist.0.0.6a6a33c6D4dIGe&algo_pvid=bf48f577-bae3-4df7-84eb-8967158c4953&algo_expid=bf48f577-bae3-4df7-84eb-8967158c4953-17&btsid=b8d0e5bf-08b6-4909-881e-19e2ddae7da0&ws_ab_test=searchweb0_0,searchweb201602_7,searchweb201603_53 I have also ordered a hot end that allows mixing like the OEM one. This new hot end should mount identically to the one above. https://www.aliexpress.com/item/4000396086553.html?spm=a2g0o.productlist.0.0.107619a4UbHM7B&algo_pvid=c867c57c-dc1e-4c86-b38d-650e5bafcb36&algo_expid=c867c57c-dc1e-4c86-b38d-650e5bafcb36-0&btsid=bb3d91bb-deff-4fe1-8e8b-dc5bead77b4c&ws_ab_test=searchweb0_0,searchweb201602_7,searchweb201603_53
