Ender 3 Pro Bed Leveling Dial Indicator Mount - Caliper

thingiverse

I sought a more reliable method of leveling the bed than the conventional paper test. This mount is designed to slip on and off as needed without any screws, making it quick, simple and extremely precise. I simply level on the fly during a program until I achieve the desired thickness. Then, I stop the program, clear the plastic away, mount the dial indicator and zero it at that location. Next, I jog the machine (or disable the stepper motors and move by hand) to the 4 corners and adjust the knobs to ensure the bed is perfectly level. Alternatively, you can jog the nozzle down until it touches the bed, set the dial indicator to zero and then jog the z-axis up until you reach the desired height. Then proceed to match the corners. The model of dial indicator I use is a Phase II, while the bolt used is a 1/4-20 1" length. This print is incredibly easy: no supports are needed, the speed is 60mm/s and the layer height is .2mm.
