I'm a complete noob to 3D printing and I'm trying to level the bed of my m2. I'm wondering what how much space I should leave between the hot end and the bed when its homed? I'm using tomlombardi's profile with a layer height of 0.25.
I'm assuming that incorrect calibration/distance from the hot end is the reason the front two corners of my prints keep curling by about 1-2mm.
Any help is appreciated.
