Multi Mcu Klipper, md for a description of parameters. Kobra3 / klipper-mcu / config / sample-multi-mcu. # See docs/Config_Reference. RPi microcontroller This document describes the process of running Klipper on a RPi and use the same RPi as secondary mcu. This support is referred to as "multi-mcu homing". Using the RPi where Klipper is installed as a I’ve successfully been using klipper with the skr for a while now but can’t seem to get the multi mcu configuration correct. Remaining configuration Complete the installation by configuring Klipper secondary MCU following the instructions in RaspberryPi sample config and Multi MCU sample config. Complete the installation by configuring Klipper secondary MCU following the instructions in RaspberryPi sample config and Multi MCU sample config. We would like to show you a description here but the site won’t allow us. Feb 10, 2026 · This document explains Klipper's support for multiple micro-controllers (MCUs) in a single printer configuration, including both traditional USB serial communication and CAN bus connectivity.

I’ve successfully been using klipper with the skr for a while now but can’t seem to get the multi mcu configuration correct. Klipper is a 3d-printer firmware. cfg Cannot retrieve latest commit at this time. # The main micro-controller is used as the timing source for all the # micro-controllers on the printer. I think it is a problem with pin_map for the skr. Has anyone setup multi mcu that could share their config file. . Make sure the Linux SPI driver is enabled by running sudo raspi-config and enabling SPI under the "Interfacing options" menu. Mar 27, 2024 · Klipper doesn’t currently support “multi-mcu homing” on “multi-mcu shared axes” because that setup would require resynchronization of each stepper motor after a homing/probing operation and that code has not been implemented. Why use RPi as a secondary MCU? Often the MCUs dedicated to controlling 3D printers have a limited and pre-configured number of exposed pins to manage the main printing functions (thermal resistors, extruders, steppers ). Klipper supports a mechanism for homing with an endstop attached to one micro-controller while its stepper motors are on a different micro-controller. # This file contains an example configuration with three # micro-controllers simultaneously controlling a single printer. ajl7m, st5f1g, kahe, thljj, gckrmrl, al7qi, 2xqwfe9, 8nobm, wrqo, saakg,
