I have a Mendle with gen 6 electronics and every time i start printing, it does not print the first layer. So the printed object becomes unstuck easily.
I am using Redsnapper and printing with 3mm PLA
Is it attempting to print the first layer (extruder gears are driving) or not? If it's trying, you might need to prime things before trying to print the first layer. Use the skirt feature in Skeinforge to print a perimeter around the object before you start the first layer.
