Thanks found this when I Googled M302 parameters I was looking for the parameters to tell me how to extrude X amount, but it seems the M302 (plus params) just allows the cold extrusion, then I have to either use a separate command line to tell it how much to extrude, or simply use the extruder jog control (using simplify 3D).by Bad Wolf - Reprappers
Thanks Shank man, yes I am using Marlin (Marlin-PI3_Pro_B ), although I am new to it, so could you please explain what that command might look like and where I would execute it from.by Bad Wolf - Reprappers
Just trying to extrude some filament to calibrate the extruder on my new Geeetech Prusa i3 mk8. I can take the nozzle off so it comes straight through, but I don't want to heat up the hot end or the filament will melt. Is there a setting in configuration.h that I can make that will allow it to ignore the safety setting and allow it to extrude unheated?by Bad Wolf - Reprappers
