Multi Mcu Klipper, 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. . I’ve successfully been using klipper with the skr for a while now but can’t seem to get the multi mcu configuration correct. This support is referred to as "multi-mcu homing". Has anyone setup multi mcu that could share their config file. 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. Make sure the Linux SPI driver is enabled by running sudo raspi-config and enabling SPI under the "Interfacing options" menu. Klipper is a 3d-printer firmware. RPi microcontroller This document describes the process of running Klipper on a RPi and use the same RPi as secondary mcu. cfg Cannot retrieve latest commit at this time. md for a description of parameters. Complete the installation by configuring Klipper secondary MCU following the instructions in RaspberryPi sample config and Multi MCU sample config. Kobra3 / klipper-mcu / config / sample-multi-mcu. Contribute to Klipper3d/klipper development by creating an account on GitHub. I think it is a problem with pin_map for the skr. 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. # See docs/Config_Reference. # This file contains an example configuration with three # micro-controllers simultaneously controlling a single printer. Remaining configuration Complete the installation by configuring Klipper secondary MCU following the instructions in RaspberryPi sample config and Multi MCU sample config. Klipper supports a mechanism for homing with an endstop attached to one micro-controller while its stepper motors are on a different micro-controller. 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 ). # The main micro-controller is used as the timing source for all the # micro-controllers on the printer. q6g0, peqg4p, ggo, 8yo, flzb, jgsa, ybauhu, 9fg, jv1xf77, we,
