Topic: cold extrusion

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

Re: cold extrusion

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..

Re: cold extrusion

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.
