Euclid was a Greek mathematician who studied geometry. It seemed fitting for the probe that studies the plane.
A highly accurate, magnetically coupled Z-Probe that is not affected by bed temp, bed material, magnetism or surface treatment.
The probe can be configured to be used as a Z-probe, an endstop, or used as both.
Euclid Probe can be manually or automatically deployed via gcode macros and can take advantage of your firmware’s probe pickup detection scheme to ensure probe pickup and docking.
Euclid Probe uses screw attached magnets for both mechanical coupling and for electrical contacts. It is simply the most reliable and secure method for attaching the magnets to the parts. The Z-Probe circuit is completed when the probe is attached to the dock.
Discussion and support is available as a subgroup to the CroXY Discord
NEWS FLASH – in collaboration with 713maker.com we now have a super-lightweight machined 7075 aircraft aluminum mount for RailCore printers! The mount weighs in at a mere 6.5 grams- that’s less than the combined weight of a nickel and penny! Its the best, reliable probe solution for your RailCore 250, the 300 and the ZL/T series.
Available as Kits & Assembled Probes
Kits available with pre-populated SMT LED’s and resistors, ready for final thru-hole soldering assembly of switch and connection headers, polarized magnets and required hardware. Fully assembled & tested probes ready for deployment, cables and accessories too!

We have probe dock and mount designs available for CroXY, Railcore, Voron, Eustathios, Wanhao i3.
Currently developing for Ender, Tiny-M & Voron Mini-AfterBurner
We have compiled configuration examples for Duet/RepRap Firmware, Klipper & Marlin and probe deploy/ retract macros
Probe Accuracy Testing
Little to no application data is available for the switches used in Euclid Probe. Therefore, the engineers and designers who created Euclid Probe embarked on their own testing campaign to qualify the switches and the other components used in construction. This includes mechanical accuracy testing of the individual switches, the entire probe assembly, and actual probe deployment and probe docking cycles on our test printers.
To date, over 100,00 probe deploy-probe-retract cycles have been performed. The only probe docking failures were due to operator error- not updating the probe Z-offset dimensions between sample changes.
The gathered data is compiled and analyzed to compare the performance between different switch manufactures and models. The overall results have been quite revealing- the usual suspects are not as accurate as they are purported to be, and the brands and models often dismissed are actually quite accurate.
Here is an example of a single switch’s probing results performed at room temperature.
Troubled with inconsistent first layers, we sought to add a Z-probe to our printer with the hopes improving it. Our initial probe was a hand deployed endstop switch on a clamp. While it worked well, it was tedious to mount and un-mount. Then we tried a number of devices that showed promise and were more user friendly. Ultimately, nothing seemed to work as well matching the accuracy that the microswitch provided.
