PT100 Amplifier Board


Hello,
I have an E3D PT100 sensor cartridge that I am trying to connect to the RADDS board. But when I turn on my printer, my LCD displays: "Temp. Sensor defect." Can you help me please?
Thanlk you.

Kind Regards;

R.H

  • You can not connect it to the thermistor connectors! You must use the adc pin on the long side center opposite to motor drivers and select the analog pin channel as input. Just not sure if you need to 3.3v or 5v PT100 table for conversion but both would show temperatures. The wrong one is easy to see when room temperature is way off.
  • Ok. Thank you.
    One other question please  about the ensdtops.

    I have a mechanical endstop V1.2.  Belows whats I did in the program. My problem is that the endstops doesn't stop the axis!

  • Please check with M119 if they are normally low and high when you trigger. Especially which one triggers in case you used a wrong pin header on board. You data missed homing direction but with these end stops they must have home directions -1 for all. All other values seem to make sense. Inversion might need toggling when M119 states signals wrong way around.
