For some reason my thermistors lost their resistance after boiling them in hot water...

Phaedrux

@Pertti Maybe they need to dry out?

Pertti

Yes indeed, now that they are dry they work fine. But the board has something wrong. The bed thermistor pins work ok with boiled thermistors, but the heater thermistor pins give 2000 degrees when tested with the "unboiled" bed thermistor.

Pertti

I also made changes to the config.g. I wonder if it has something to do with the problem.

I think there´s something wrong with the board.
Some fuse I guess?

jay_s_uk

@Pertti that just means you haven't set up the temperature sensor correctly.
Your T values look a little low.
Can you post your latest config settings?

I told above that I boiled the thermistors when calibrated them and after that this happened.

Pertti

New fuse is installed, but no effect.

The T100 values in the M305 H0 and M305 H1 commands are not right. Try T100000 which is what you already have in the M305 H0 command.

You don't need the R parameters, because the firmware knows what values the series resistors have.

Pertti

I changed the configuration, but the temperature stays in 2000C as in picture 16 Jan 2020, 20:19

@Pertti 2000ºC means the pins are shorted. -273ºC means the pins are disconnected. If you disconnect the temperature sensor, does it go to -273? If not, check your VSSA fuse replacement soldering. Alternatively, connect a 100k resistor to the pins, which should read 25C. I have these for just this occasion:

Hi droftarts

all temperature sensors disconnected -> temp 2000C
-E0 temperature sensor connected (100k measured) -> 2000C
E0 temperature sensor connected to Rumba worked ok

Please post the config.g file that you are now using.

In the M305 P1 and M305 P2 lines, change T100 to T100000 just as you have already in the M305 P0 line.

You can remove the R4700 from all 3 M305 lines.

Thanks 100000 times!
Now both thermistors can be read.
