Mounting bracket for 2020 alu frame for H3+ extruder

thingiverse

This is a mounting bracket to secure the H3 / H3+ extruder on a 2020 aluminum frame.\r\nCompatible models:\r\nhttps://www.thingiverse.com/thing:2277417 \r\nand https://www.thingiverse.com/thing:27626\r\nI installed this extruder on my Tronxy X5S printer, mounting it to the top back right corner with the filament feeding in the same direction as the original extruder.\r\nUsing the original Stepper motor (Nema17).\r\nThe new steel hob-gear is slightly larger than the brass one that came with the printer.\r\nTwo of the Tronxy idler bearings were reused for the big gear axle/shaft.\r\nFirmware not yet updated, still running the X5S as original. I modified the start g-code to M92 E440 instead of M92 E100 and it worked perfectly after a power cycle.\r\nI am also experimenting with coasting and restart distance to optimize the starting point when the extruder feeds without delays or skipping.\r\nThe mount is designed for Tronxy X5S but should fit other 2020 or 2040 aluminum profile printers. The CR10 model may also be compatible, as it features a simple (high skip rate) extruder that could benefit from this upgrade.
