MMSU

MMSU - Multi Material Switching Unit If you like the project, you can support me here: https://coff.ee/mayster Boost MeTHANKS!Hey, I’ve created the MMSU, which is based on parts from the MMU PICO. It’s a side project of mine, but it turned out so well and works so smoothly that I decided to share it. I hope you’ll like it! MMSU has a NEMA 17 stepper motor which serves as the second extruder, and a 180-degree servo that selects which filament is currently being pushed by the stepper motor. Personally, I have connected this motor directly to the mainboard—both the servo, which I control using a free Neopixel port, or if available, a free port for the BLTouch servo (important: make sure to power the servo properly so it can draw around 2A—I use a separate converter for this). The stepper motor is connected to a free slot for a TMC2209 driver. I use RepRap firmware and a BTT Octopus board. I don’t have any config files for Klipper or Marlin the MMSU project is based on the MMU Pico:https:/
