Looking at Voron #3667 and it did not take very long to find that one of the stepper motor lines has a discontinuity. Somewhere.
Rather than try to replace one wire, the logical choice would be to replace the entire toolhead harness, since it’s likely to have another break at some point. However, replacing the whole wire harness would be a huge pain, and more costly than going CAN on account of the expensive wire you need.
So, I’ve already placed an order for a Mellow Fly SB4020 CAN toolhead board and the accompanying wire harness. At first I was apprehensive about going CAN just due to the scattered nature of information I was finding, but I think I’ve managed to find enough quality procedures to do each part of the upgrade.
The first step will be to remove the old wiring harness in preparation for CAN. I will be sticking with the cable chains for now, but I’m currently researching the umbilical that I can always add later.
