Hi,I have a Creality Ender-3 Pro and am using a PLA+ filament. I edited my firmware to enable print pausing via the M600 command inserted into my gcode so that I can change filament colors at certain levels. Everything works fine with it, except when I resume printing, the filament doesnt stick to the existing part that was already there. Im fairly new to 3D printing, but my thoughts are that maybe its because the bed has cooled down? Or maybe when the print head returns to the part, the z axis may be too high? All guesses of course! If anyone has any thoughts on this, please help me out. Thanks!
