Lower dual E3D v5 hotend 4 Mankati Fullscale XT

thingiverse

Important Note: Mankati revamped the motherboard in recent versions, necessitating tracing all connections using a multimeter and identifying pin definitions independently before incorporating them into your Marlin configuration .h files and compiling them. Currently, there is no known working configuration file for these updated editions. This setup has increased stability and facilitates effortless hot-end changes without disassembling the XY carriage. I've opted to remove one hotend to minimize weight as I predominantly print with a single material now. Always adhere to instructions and avoid shutting down the printer without first cooling the hotend. Assemble your 3D printer using these components: 4pcs. M3x25mm screws for XY bushings, 2pcs. M3x20mm screws per hotend bracket, and 2-4pcs. M3x15mm screws for the fan. Customize your printing options with one of three parts: dual hot-end fan shroud, single hot-end fan shroud, or the main body housing XY bushings, hotends, and quick connect PCB. Print the fan shroud with the fan side down, requiring minimal support. The dual hotend fan mount includes provisions for spring-loaded contacts to power the fan; the single fan mount necessitates using a connector (or adapting it yourself to use the spring contacts). Attach the two small FR4 1.5mm PCBs on the dual hotend fan mount and solder both fan cables, observing polarity. Assemble your hotends according to manufacturer instructions, slide them into the body, fix with brackets and screws, and finish wiring to the top PCB as desired. Replace the Mankati PTFE Bowden tube with a better quality one, keeping it short. Slide the fan shroud onto the hotend, using the right (second) fan cable for continuous power. This design maintains nearly the same Z height as the original while requiring adjustments to be verified first. The attached firmware was constructed using Ginge's Marlin Builder at http://marlinbuilder.robotfuzz.com/ and includes a raised top temperature of 300°C, reduced X axis length by 250mm, and Y axis length by 230mm (shortened by 20mm). Perform PID training after installation. Unfortunately, due to linking restrictions, the firmware is attached instead.
