I’ve begun tearing out the old wiring harness on #3667. First the right-hand side panel comes off, then the extruder, then the cable chains:
It didn’t take long for me to find the broken wire, it was in the x-chain close to the toolhead:
Next step is to finish removing the z-chain and then pull the wiring harness completely out of the machine. After that I plan to upgrade the Pi OS and Klipper. By then the parts for CAN should be here.
