My Ender 3 Max needs another update: Klipper with SKR Pico and Hermit Crab CAN. The packaging of the Hermit Crab CAN is really nice, everything I need is included and I can’t wait putting alls things together. As the CAN HAT uses the same ports as the SKR Pico, I will have to use the SKR Pico with USB or add a CAN interface…
20220815 nice Youtube video found for Hermit Crab CAN https://www.youtube.com/watch?v=-a2LpqCYQq4
20220816 Added CAN HAT according to the youtube video.
Changed the serial port for the SKR PICO to uart3. To enable the uart3 on the Raspi 4 I added
dtoverlay=uart3
to my /boot/config.txt. Rewired the SKR PICO (maybe I make a custom cable later) and changed the serial port to /dev/ttyAMA1.
