5. Betjeningsvejledning

5.1 Firmwarekonfiguration

The Octopus Pro V1.0 supports Marlin2.0, Klipper, and RRF firmware. You will need to compile and flash the appropriate firmware for your specific 3D printer configuration and desired features. Detailed guides for firmware compilation and flashing are typically available on the BIGTREETECH GitHub page or community forums.

• Marlin: A widely used firmware for 3D printers, offering extensive customization.
• Klipper: Known for its high performance and flexible configuration, often used with a Raspberry Pi.
• RepRapFirmware (RRF): Offers advanced features and web interface control. Note the 512k flash memory limitation for the STM32F446ZET6 chip when using RRF.
