How to disable Marlin cold extrusion prevention via G-Code
If you want to test your extruder, you can disable cold extrusion prevention using M302
:
M302 P1
Re-enable with
M302 P0
Set the temperature (and enable) using
M302 P0 S170
In order to **report the current status,**run
M302
Example output if disabled:
echo:Cold extrudes are disabled (min temp 170C)
Example output if enabled:
echo:Cold extrudes are enabled (min temp 170C)
Whatever you configure will not persist after reboot. In case you want to save the settings to EEPROM in order to persist after reboot, run
M500
