README
README.mdPicoMMU
PicoMMU is a PCB designed to control a stepper motor and servo for a multi-material unit. It is compatible with Klipper firmware.
Requirements
- A USB C cable to connect to your RPI / Printer
- A 12-24V power supply
- A TMC2209 (BTT Recommended)
- A stepper motor crimped with a 4 pin JST XH B4
Flashing Klipper
- Follow this Klipper guide on how to build the firmware. The first image shows the configuration settings and the second shows the "Optional Features" section.
- Once the firmware is build, put the chip into DFU mode by clicking the reset button while holding the boot button.
- Run lsusb and take not of the numbers in this format: xxxx:xxxx.
- Now use the following command to flash the firmware (replacing xxxx:xxxx with your MCU's ID):
make flash FLASH_DEVICE=xxxx:xxxx. - Unplug and replug in the USB cord and your MCU should pop up in
ls /dev/serial/by-id/*.

Questions
How big is the PicoMMUBoard PCB?
It measures 48 × 40.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PicoMMUBoard use?
35 parts, built around the AMS1117-3.3, USBLC6-2SC6 and TMC2209. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PicoMMUBoard KiCad files?
From the AdamTuraj/PicoMMU repository on GitHub, at the commit this page was made from: the board is Kicad/PicoMMUBoard.kicad_pcb and its schematic Kicad/PicoMMUBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PicoMMUBoard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
