Bed Thermistor 92_8

Miken

Hello Repetier,

since you release 92.8 the bed thermistor (in both lcd and host) presents wrond temperature. If i switch to 92.6 everything is fine.
My thermistor is

100k Epcos B57560G0107F000

Repetier

Haven't changed the tables. Could it be that the pin number has changed instead? What board are you using and which thermistor type did you select?

Miken

Rambo board and bed thermistor is 100k Epcos B57560G0107F000 (on pin TEMP 1 normally used for heated bed).
With the same Configuration.h is fine at 92.6

Repetier

I have checked pins.h and temperature curve and both are unchanged. Even more I have printer with these thermistors and they are still running fine, so the problem is not the thermistor. It must be something different.

I guess best would be to find the exact commit that caused the problem. Then we know it must be a change in the modifed files. Github allows you to download every in between version you like.

Also what do you mean with wrong temperature. 100° difference total nonsense...

Miken

Room temperature is let's say 18 Celsius degrees. Without printing anything, on 92.6 firmware bed temperature is 18 Celsius, but on 92.8 bed temperature is 1.1 Celsius degrees.

I haven't change anything. I'm using the same configuration.h.

And it still goes up/down when heating? Not that a other function uses the pins modifying the result, cause my printer still shows room temperature. I guess only finding the commit causing the error will tell us more ore give us new ideas where to search for this special problem.

Miken

Yes it goes up and down but in lower scale.
Let's say from 1.1 to 1.58 etc.

I also tested on 92.7 and it's ok. When flash the 92.8 here comes the error.
I'll check your submissions.
