Error: Heater 1 fault | Hotend not heating up after good print
-
SOLVED: Not entirely sure what the solution was. First I changed the heating cartridge wires to e1heat. The LED for e1heat turned on, but it still wasn't heating up and triggered the fault. I returned everything back to e0heat, and still no good. I removed the heating cartridge and thermistor from the hotend, then put it back together, and cut off 6 inches of wire from the heating cartridge, tested continuity in the cut off segments(continuity good), striped the new wires and plugged them back into e0heat and it worked.
My Anycubic Kossel Plus Delta printer has been working fine for the last 4 or so years. I printed something today and noticed that the layers were slightly wobbly, so I tightened all 3 of the belts. Then I ran a delta calibration (G32) and a mesh compensation (G29). The G29 command told me I should adjust my Z height, so I adjusted the following in config.g:
G31 P1000 X0 Y0 Z15.30
I ran g32 and g29 again, and all was well. I did the sheet of paper test and brought Z down to 0, it was perfect. I reprinted my wobbly part and it looked great. I ran g32 and g29 again and tried to print something else, and I got this error:
Error: Heater 1 fault: temperature rising much more slowly than the expected 1.7°C/sec
Currently my hotend is hovering around 27-28C according to the webUI, so it seems the temp sensor is working. I checked the wiring, and it looks fine. I reset the fault and tried to heat the hotend again, and got the same error. When I try to heat the hotend, the HEAT LED turns on until the fault is trigged, then the LED turns off. Bed heating works just fine.
Things I've tried so far:
- Restart the printer
- Refresh the webUI
- Disconnect and reconnect the hotend wires from Duet3d motherboard
- Disconnect and reconnect the temp wires from Duet3d motherboard
- Touch the hotend with my fingers to make sure its not actually hot
Any idea how I should proceed? If I had to guess, I would say that my hotend just suddenly died?

Any idea how I should proceed?
If you’re familiar with a multimeter, you can check the voltage at the Duet’s heater port and at the hotend when the heater pretends to be active: values of approx. 12V on both ends indicate that the wiring is presumably OK. In addition, check continuity of the two lines.
You can reconfigure your config and the wiring to use e1temp. If the hotend then heats up, the port e0temp might be faulty. Else, replace the heater cartridge.

@infiniteloop Im only mildly familiar with the multimeter. When I test for continuity between the cartridge heater (i placed the probe on the round end of the heater) and the wire for the heater, there is no continuity. I'm not sure if I am placing the probe in the wrong place. So when I tried to test for voltage while it was pretending to be active, I got 0 volts.
How would I change the config to use e1temp? Would I just change H1 to H2 like this: "M950 H2 C"e0heat" T1"

First, I’m sorry having confused the sensor and the heater port names
Now, in order to use a different heater port, you just have to change this line in your config
M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
to this:
M950 H1 C"e1heat" T1 ; create nozzle heater output on e1heat and map it to sensor 1Your heater is still called H1, and it will still be mapped to sensor 1 (T1), but now, the Duet assumes the heater to be connected to a different port. That’s exactly what you have to do next: wire the heater to e1heat of the Duet.
