thermistors on due

Open maukcc opened this issue 6 years ago • 0 comments

Firmware version 4.3.3_dev

My setup arduino due with 100K epcos thermistor with 4K7 pullup resistor to 3V3 for the bed and chamber. The extruders are on AD595

Normally the pullup resistor for the thermistors go on 5V, but with the due it is on 3V3. I am getting strange readings now. Tried to compensate with:

#define THERMISTOR_SERIES_RS 40000.0 // compensation for Due 3V3

but that does not give correct readings
