Cancelling extruder thermistor input. was created by mary22
I have a SKR Pro 1.2 board with Marlin code. Setup from MP CNC firmware. This is set for a 3D printer and the touch screen works for all movements. I have added a paste applicator that uses the extruder
stepper motor
to apply the paste. The firmware is checking for a signal for the hot end temperatures. I want the extruder to run without checking for temperature. I am not experienced in writing the Marlin code and reflashing the firmware. Can I add a resistor to fool the thermistor or a code that stops the firmware checking?

Moved to "additive manufacturing".

There should be a setting with "minimum extrusion temperature" in marlin.
And yes, you can do it with a resistor or a potentiometer.

This really isn't a LinuxCNC question, it is a Marlin question.
Removing M109 (and maybe M104) from the G-code (and if that works, from the preprocessor that generates the G-code) will probably do what you need.
