Update! - All euclids are now 24v capable - whether your system voltage is 3.3v, 5v or 24v (replacing inductive probe) the euclid can handle it! The highly accurate and magnetically coupled Z probe for your 3D printer, laser and CNC machine. Check it out in action below. There are so many different bed sensing options out there, so why Euclid? Direct Surface Sensing Swap out your surface for glass, textured, PEI, PEX, Blue Tape, whatever! Euclid can sense them all Reliable Probing Even at a 10mm/s probe speed, standard deviation is .0021 in a sample size of 50 probes Direct sensing of the bed - not affected by bed magnets, humidity, No servo needed, no waiting between probes, no settle time - probe quickly and without failure Reliable Deployment Polarized Magnets for one-way docking Circuit is completed through magnets - if docking fails for whatever reason, printer can detect and error Atomized docking components are pre-made for any application - simply add geometry to attach to your machine and enjoy tried&tested geometry Durable Switches are standard industrial switches used in a wide variety of applications Docking the probe allows significant toolhead clearance when not in use No moving parts are installed while machine is in use - nothing to get caught during an errant print or if the sensing pin decides to drop and catch things on its own https://twitter.com/LukesLaboratory/status/1420766762547748865 Included: 2x Euclid PCB's 2x Polarized Magnet Pairs 4x Flathead Screws for magnet mounting 1x JST-XH 3position header 1x Omron Switch Check out the github here: https://github.com/nionio6915/Euclid_Probe All purchases support the original creator Installation notes: The holes for installing the board on the printer are sized for m2.5 screws. There is enough PCB space to drill out for m3 clearance hole.
