Extruder motor bypass
I have built a custom extruder head for my printer that prints a low temperature material at 60°c however when I try to print an object the motor does not spin because it has not reached a high temperature because it is thinking it is printing plastic. Is there a way to bypass that or remove that.
RE: Extruder motor bypass
Yes. There is a low temperature extrusion gcode that allows you to change the threshold.
The default value is 170c.
Make it say 40C.
And you should be good.

Where is that gcode and where should I put it
RE: Extruder motor bypass
The Gcode is visible in the REPRAP Gcode list
And you put it in the custom gcode start gcode
Search REPRAP Gcodes
I followed this link
https://reprap.org/wiki/RepRap_Firmware_G-Codes
I Searched for Extruder and came up with this link
I followed the link and got this information
https://reprap.org/wiki/G-code#M302:_Allow_cold_extrudes
so. if you put the command
M302 S40
Into the Custom Gcode, Start Gcode (In Printer Settings)(Might meed to be in Advanced Mode or Expert Mode)
your printer should allow extrusion at temperatures above 40C
