[jaydevdave]

Hi,

My PT100 sensor works fine when i start a machine.
But when i shoot Extrude Command or Retract Command then temp. goes to 2000C

The same configuration works fine with thermo couple.

Please help

I'd say it's picking up noise. Shielded cable might help.

@jaydevdave yeah as Ian says interference is a likely culprit. Look at the routing of your cables. Also the connections.

Yes, it sounds like your PT100 wires are unshielded and running close to the extruder stepper motor wires.
