what thermistor in bed? Model and picture pls

100K ohm NTC 3950FB Thermistor is used, and I should be home shortly to send images

from ender-3.

As soon as You get home, try to check the connection of the therm... with the board... even with a len, check the cables are properly inserted in the thermistor board. This is the most common issue. If the connection are 100% probed well, try with another thermistor, may be you are unlucky and buy a defective therm...

I checked both connections and even on the bed as well. Here are some photos I took. The first one is the board with the two thermistors plugged in, the second is what the display normally shows, and then the third photo is what happens when I set the nozzle temp without touching the bed temp at all

i hope these help

If You remove the bed therm.... what happens? preheat the noozel heat, then disconnect (with the noozle in heat) the bed therm and puth the noozle/head in the bed place... check lectures in the lcd

When the bed pin therm is removed, nothing happens, it still shows that there is a temp on the bed, which obviously isn't normal considering the therm is removed. I tried heating the nozzle, but it still shows the bed heating up alongside the nozzle. When the nozzle is disconnected the bed shows 0 and an error on the nozzle. I tried plugging the bed therm into another port other than the dedicated therm bed port, and it still doesn't change anything

I also tried switching the pin config with the other port for the bed, and it does show 0, which is new, but.... now when I go to heat it, it comes up instantly with a heating error

from ender-3.

The thing is, make that change, whatever is working will change temperature, so the voltage over the connection in the board, this is for know if its the sensor/therm or worst, THE BOARD input for sensor, this Analog port can be broken, that's why I would change sensor in the other port to test if as well as it cooled, then show changes in temperature over the LCD

pictures to your code, do You define the EXACT model of board in #define board MY_BOARD (OR Whatever), the ports (analog) are different between different boards... check it out

It never CAN SHOWS zero, but the environment/room temperature .... if it is OK

from ender-3.

the heating error is because once you activated the heating process, the thermistors reading are not showing appropiate lectures, the port of your board can be broken too

So I had my friend, who knows more than I look at it, and we actually fixed the problem. Apparently, the bed pin on the btt octopus was broken somehow jumping and connecting to the nozzle thermistor pin which is why it also read the same as the nozzle, and we figured out why we simply couldn't change the pin to another thermistor port and change the config so that it was changed to that new port without an issue and now have resolved the issue and now everything works, thank you for your help it was greatly appreciated :)

Great You can fix your issue... best regards
