Thermistor issues

Please Login to Comment

My OEM thermistor went out, I've been running Repetier for years. I replaced it with the "standard" 100k NTC as is "normal" but not for the Davinci 1.0 apparently. (I've researched this a lot). So I'm up and running again but doubting the temps that the LCD and Repetier are reporting are accurate. I've got the new thermistor attached to the PCB on the extruder cartridge as in OEM. I have not messed eith R29 on the mother board. The hot end is original (for now, I'm working on printing the bits to go E3dV6. Should I bypass the extruder PCB as I understand there's a resistor in there, or is that the R29 on the mother board? I can clip it out. Or leave it alone until after the hot end upgrade?

I'll reply to myself.
So, I swapped thermistors but retain the original Davinci 1.0 hot end (for now) so maybe the temps are accurate as, if I'm understanding it, XYZ has a resistor on the mother board that changes values to accommodate their hot end even though the thermistor is "standard" 100k NTC, if true, then I should be good yet until I do a E3dV6 swap, THEN I should have to do something to the board (remove R29 I believe) to get somewhat accurate temperature reporting. Yes? I think.
