Cetus3D Z probe holder

This is a holder I designed for a precise Z probe for bed levelling. It allows for very precise bed levelling with small offset from nozzle. Compared to it inductive probes are crap. I used it to do grid compensation in smoothieware. My bed is extremely uneven, but after compensation my Z offset is uniform throughout all the corners. You can find guides on the grid compensation on http://smoothieware.org/zprobe

Use two M2.5 12mm screws to fasten the switch. Before performing calibration tempo
