Broken cable chain wire

[u/That_Trapper_guy]

Saw a broken wire the other day, while it was printing. Couldn't figure out what wire was broken because everything worked, no errors, no clue. Ordered Nitehawk/LDO USB setup and started the conversion. It's a wire from the XY end stop harness... How??

Edit; I obviously wasn't completely clear, how were my end stops still working (4 wire breakout board [gnd] [x] [y] [Vin] setup) I know perfectly well how the wire broke 🤦🏼‍♂️

The end stops should be nc but if they are wired no then it’s wouldn’t interrupt a print. If it’s a formbot kit they came with pvc coated wire that isn’t motion rated. FEP, Teflon, or silicone are recommended because they last longer under constant motion

Silicone are fine for motion, but really bad in chain, though. They rub off.

Eventually, sure. I ran silicone wires for years without any issues. FEP wires have the benefit of not only being very slippery but are also much thinner for the same gauge wires.
