I am currently running repetier 0.92.9 and have needed to install a new thermistor in my hotend.
The thermistor is an epcos 100k B57540G1104F
I have attached it to my hotend and used the repetier config tool to add the custom thermistor table.
Once I added the 20 values given here on the wiki [
reprap.org]

// EPCOS 100K Thermistor (B57540G0104F000) // Thermistor lookup table for RepRap Temperature Sensor Boards (http://make.rrrf.org/ts) // Made with createTemperatureLookup.py (http://svn.reprap.org/trunk/reprap/firmware/Arduino/utilities/createTemperatureLookup.py) // ./createTemperatureLookup.py --r0=100000 --t0=25 --r1=0 --r2=4700 --beta=4066 --max-adc=1023 // r0: 100000 // t0: 25 // r1: 0 // r2: 4700 // beta: 4066 // max adc: 1023 #define NUMTEMPS 20 short temptable[NUMTEMPS][2] = { {1, 841}, {54, 255}, {107, 209}, {160, 184}, {213, 166}, {266, 153}, {319, 142}, {372, 132}, {425, 124}, {478, 116}, {531, 108}, {584, 101}, {637, 93}, {690, 86}, {743, 78}, {796, 70}, {849, 61}, {902, 50}, {955, 34}, {1008, 3} };
I got a reading of over 1400 degrees which caused my printer to show "def / 0" and beep at me.
I then went into the firmware and opened coniguration.h and changed the values to the original numbers (as the config tool changed them to what it needed) and got a reading of 165.5 degrees which wasn't changing.
I then multiplied the temp by 4 and the resistance by 8 an now i get a reading of 851.1 degrees whih hen beeps and says "def / 0" again
What am I doing wrong?
