Heater problems Duet2 Wifi
-
I caused a heater cartridge short (I believe), I accidentally worn the wire insulation to the hot end down by overtightning the assembly.
I replaced a blown 7.5a fuse, insulated the wires with electrical tape as an attempt to revive it.
Now I'm having thermister faults...
I changed the thermister as I thought that was the issue, but I'm getting VSSA faults on both the bed and hotend, after the bed has warmed up and while the hotend is warming up?
I read that a heater cartridge short can cause VSSA fault, so should I assume that I need to replace the heater cartridge?

I could have damaged the VSSA fuse on the board. Can you try the other heater terminals? E1 instead of E0?
-
@Phaedrux Do you mean switching the "terminals" so E1 --> E0?
E0 (heated bed) works fine as far as I can tell although I had to do a PID autotune after the suspected short, and the bed is heating slower than I remember.
-
The bed should be on the bed heater terminals? Is it a DC heated bed?
-
@Phaedrux Uhm, do you mean phsyical screw terminal? In that case it is, and yes it is DC.
Apologies for dumb questions... Still learning

Usually the bed would be connected to the bed heater terminals since the bed is usually high current draw unless you are using a mosfet or ssr to switch a different power source.

I did turn out to be a hot end short causing the weird errors. Closed.
