Katapult Firmware
Katapult Firmware Description
Tip
Katapult was originally named CanBoot and later renamed to katapult.
- The Katapult firmware is a type of bootloader that can be used together with Klipper. After flashing via DFU or other methods, firmware can be updated with a single command.
- Advantages: Quickly double-click the reset button or power cycle twice to enter the Katapult firmware, at which point the LED on the motherboard will blink.
- Katapult firmware can only be used to flash firmware and cannot connect to Klipper!!!
- Katapult firmware supports three ways to connect to the host computer, and the firmware for each method is independent.
- CAN connection
- Advantages: After compiling the Klipper firmware, it can be updated directly using commands, with strong anti-interference capability.
- Disadvantages: The firmware compilation speed needs to be known in advance.
- RS232 connection
- Advantages: After compiling the Klipper firmware, it can be updated using commands, with very strong anti-interference capability.
- Disadvantages: Firmware cannot be updated with a single command; manual entry into Katapult firmware is required.
- USB connection
- Advantages: After compiling the Klipper firmware, it can be updated directly using commands.
- Disadvantages: Long data cables are prone to interference, which may cause disconnection.
- CAN connection
Tip
- TOOL-LITE supports CAN
- Only 1M CAN firmware is provided here
