Hictop Prusa I3 Print Table Leveling Calibration Tool

thingiverse

I have developed a print table leveling/calibration system for my printer. The Z-axis is locked in place with the green height setting blocks, which are designed to raise the print nozzle high enough to clear the print table surface, allowing the extruder assembly to be moved to its center of travel and out of the way. To ensure equal height, I printed both green blocks at the same time. The pointer and attachment bracket are set up for 3mm diameter machine screws. The bracket clips onto the 8mm linear rods of the X-axis, and the pointer height is set at the "home" corner for the extruder nozzle. To make adjustments, simply lower the pointer to rest on the surface of the print table and tighten the screws. Once the initial setting is made, move the pointer assembly to the opposite side of the X-axis and adjust the corner opposite to the "home" corner height. Pull the print bed forward and repeat the level-setting process for the aft two print table corners. Visual instructions can be found in the photos provided.
