Klipper started throwing an error and shutting down while trying to heat the extruder. The extruder was cold, which basically meant a heater wire break. Thankfully it was very easy to find. So much for buying a nicer harness. Grumbles aside, I wonder if this wire got pinched when I assembled the chains, which lead to an early failure.

I didn’t have any spare PTFE wire on hand, so I spliced in a length of 16 gauge silicone wire and made sure to land the solder and heat shrink sections well away from any possible motion. I have replacement wire on order, but am tempted to run as is until it fails again…

    I think I have 16 AWG on it now, which is definitely overkill. It’s been a wild journey of mods so I’m not even sure what I last installed. I got rid of drag chains and the Huvud CAN board was finicky about voltage drops so I went a bit overboard. I just remember the 24 AWG copper was insufficient for CAN + Rapido HF despite the shorter run and being an IGUS branded cable.

    Here is the 16 AWG wire I used: https://www.amazon.com/dp/B089CW1YGM
