try this one : M302 S<0 or 1> - allow cold extrusion. Without S parameter it will allow. S1 will disallow.

Did not work for me, but never-mind, decided do just calibrate whit hot extruder, it just wasn't wort flashing the firmware for the calibration.

Ok thanks. I was hoping there is something like a gcode command I could use to temporarily enable cold extrusion.

Change has to be made at firmware level..

Hi,
I'am running Da Vinci 1.0 with repetere 0.92 firmware. I'am in the process of converting it to Bowden extruder so I was wondering, is there a way to enable cold extrusion in repetere? It is really annoying that in order to test my E steps I have to first heat up the extruder and only then can I extrude manually from repetre host.

Your line in question: Line 955:

#define MIN_EXTRUDER_TEMP 170
