Have any of you all attempted to make a paste extruder?

Have any of you all attempted to make a paste extruder?

Im wondering whats involved with editing the firmware temperature settings or other things to look out for. Any advice would be greatly appreciated. :slight_smile:

I did. Marlin can be pleased using either a fixed 47k resistor replacing the thermistor or by removing it and setting to 0 the lower limit on Configuration.h HEATER_0_MINTEMP

Cool thanks Miguel, did you remove all of the thermistor components or just change the firmware settings and leave the components attached?

If you leave the thermistor attached then there is no error condition happening. If you remove the hotend thermistor then Marlin will stop working as it detects a MINTEMP condition. It is to prevent it that you would set HEATER_0_MINTEMP to 0. Bed heater will not give you trouble whether it is kept or removed.

Awesome, ill give it a try!

This one get recommended in reprap a bit

An air pressure based extruder for chocolate, sugar and etc. If I am remembering my history this is basically the isomalt printers that were being used to study vasculature and bio printing.
