Hi there
I have two different sanguinololu 1.3 boards: One from Reprap.me (Sanguinololu 1.3b with an 644P) one from emakershop (Sanguinololu 1.3a with an 1284P).
I am using the Honeywell 100K Thermistor (135-104LAG-J01)
With the board from reprap.me I've got the correct temperature but with the other board not.
The board from emakershop shows me 185° for the extruder and 12° for the bed (with the reprap.me I've got 25° and 28°)
I started measuring ohmic resistance on booth boards at the bed and extruder temperature connectors
reprap.me ==> 4.7K
emakershop ==> -33.5k
So i guess I need an other thermistortables.h for the board from emakershop, right?
Here is the thermistortables.h which gives me the correct temperature on the reprap.me board:
#if (THERMISTORHEATER_0 == 7) || (THERMISTORHEATER_1 == 7) || (THERMISTORHEATER_2 == 7) || (THERMISTORBED == 7) // 100k Honeywell 135-104LAG-J01

Any hints what I can do that it also works on the board from emakershop?
