And then with the last request:
-
Your thermistor isn't plugged into the E0 Thermistor port.
It should be in the one right next to the heater terminals.
-
@Phaedrux That's what I fugured. But going off of this picture from your install guide, I plugged it into the same connector shown.
Now switching ports on the board has not changed anything with the temp shown on the 7i. It still shows a -273.1 temp still. Do I need to do a Reset Heater Fault and see what happens?
-
I knew that picture would come back to haunt me.
You'd need to power cycle the board.
-
@Phaedrux lol No worries. I was just trying to stick to what's laid out. Now I have powered down and powered back up the board. Every time I disconnect and reconnect cables I unplug the PSU cable. Still ends up saying the same thing.
-
Still doing this after fully power cycling the printer.
-
It's showing open circuit on both your heaters. Are the wires actually connected? Bad crimp?
-
Not my best but not my worst. Pins are seated properly too.
-
Just to verify
-
Last picture show the thermistor connected in parallel with the heater element.
The two pin header labeled E0 Temp is probably the one you wanted to use. It would help to measure the resistance across the two wires coming from the thermistor if it doesn't work on the correct input to see if the sensor/wiring is okay or not. I guess if subjected to Vin for some time it might not survive due to the heat generated as the resistance drops with increasing temperature.
-
@bearer Further up you'll see that it was mentioned for me to move the Therm to this connector. I did originally have it connected to E0 TEMP.
-
Maybe I fixed the photo cause I had made the same mistake originally. Will look closer tomorrow after sleep.
-
If you have a multimeter try to measure the resistance of the sensor to see if its wired correctly. Disconnect the plug and measure on the crimps in the plug, with thin enough probes you don't even have to remove the crimps from the plug. You should most likely measure around 100k ohm at room temp (20C).
-
@Phaedrux Well, just now moved it to that other set I originally had it on and still the same thing.
