Yeah... still open to suggestions... The temperature reading is even worse now! I used the beta reading of 4267k for a 104-gt2by jpotts - Sanguino(lolu)
The thermistor ohms out to 100k or pretty close to that at room temperature. I am getting 4.98vdc at the rail. The only thing I did notice is that the resistor value on R9 and R10 is 4.61 Kohm I may try to make a custom table with the beta value and resistor value to see what it changes with the readingsby jpotts - Sanguino(lolu)
I guess I should have mentioned that I was using repetier firmware. The table is set to a type 8. I will meter what you mentioned and report my findings in a little bitby jpotts - Sanguino(lolu)
Hopefully someone can help me out here... I have a Sanguinololu 1.3a board with 4.7k pullup resistors installed. I have a J-Head hotend MK V-BV (the real deal, not a knockoff) The hotend has a 104GT-2 thermistor installed. The problem that I have is that it reads values, just not correctly. For instance... repetier host is set to: 255C The Thermistor reads: 235C in Repetier My meter says theby jpotts - Repetier
