Bondtech BMG extruder mount for C-Bot

thingiverse

This is a custom version of Carl Feniak's 'direct drive' gantry for C-Bot/D-Bot printers, allowing for the mounting of the Bondtech BMG extruder. The main changes were removing the built-in direct drive system on top, extending the bottom heatbreak bracket, and extending the very top holes to fit over the new extruder. Plus, an alternate version is included! Pros: * You get to use a Bondtech BMG extruder on your C/D-bot! * If you choose the 'frontPlateAlt', you'll gain 50mm of z-height back. Cons: * You'll lose about 14mm on Y based on how much more this sticks out. Two versions are available: * *frontPlate*: This has the extruder mounted to the top and the heatbreak (I'm using an E3D-v6 Volcano) mounted to the bottom, with a bowden tube in-between. This was most similar to my original setup. * *frontPlateAlt*: This is designed to have the heatbreak mounted directly to the extruder itself. Based on how much the Bondtech sticks out from the gantry, I discovered that the E3D-v6 heatbreak and hotend will clear the gantry, meaning no more bowden-tube extension needed. Note that the *volcano* nozzle will stick down below the gantry by a few mm, allowing it to still print a-okay, but I am unsure if a 'normal' E3d hotend will be long enough for this configuration. I also included a copy of the accompanying backplate & 'groove mount clamp' files that Carl designed. You will need: * For either config, you'll need three M3x40mm socket head bolts. The BMG ships with 35mm bolts, and they're not long enough to go through the printed pieces. * For the 'frontPlate', you'll need a bowden tube 94mm long, to run from the BMG into the heatbreak. You'll also need a bowden adapter to plug into the base of the Bondtech.
