This is a multi-material upgrade for the C/D-bot and related printers, using the Prusa MK2/S Multi-Material Upgrade (MMU) kit.
Required components:
* Prusa MK2/S MMU kit
* (4x) 600mm PTFE tubes
* Misc. M3 and M5 hardware
* Dupont crimp, pins & headers
Optional:
* BL Touch
* Drag chain
* 40mm fan adapter for hotend
Although the Prusa MMU kit parts are open source and in theory you could obtain all the parts elsewhere, the retail cost of the 4x Bondtech gears is almost as much as the whole kit, and the custom metal cooling tubes and some other kit parts would be difficult (but not impossible) to source.
Firmware:
Included is a modified Marlin 1.1.6. Although 1.1.6 supposedly supports the motor switch board ("MK2_MULTIPLEXER"), I could not get it to work without these changes.
Note: You will likely need to edit the Configuration.h especially if you use a different size bed or don't use the BL Touch.
Electronics:
The motor switch board takes a 4 pin connection fr
