About Katapult

Katapult, formerly known as CanBoot, is a bootloader for ARM Cortex-M microcontrollers used with Klipper printer firmware. It was first built for CAN bus toolhead boards and now also supports USB and UART, so firmware can be updated without physically reaching the board.

It reuses a stripped-down version of Klipper's hardware abstraction layer to keep its footprint small, and comes with a script for flashing boards from the printer's host. It suits Klipper users running CAN toolboards or several controller boards.

Strengths

  • Update board firmware over CAN, USB or UART
  • Small footprint built on Klipper's own hardware layer
  • Widely used with CAN toolhead boards

Limitations

  • Requires building and flashing firmware, which is fiddly for beginners
  • Only useful for Klipper setups on supported microcontrollers
