Klicky Probe

Microswitch probe with magnetic attachment, primarily aimed at CoreXY 3d printers.

Initially it was focused on the Voron printers (V2.4, V1.8, Trident, V0) and derivatives, now it's been restructured to better allow other printers to be documented on the main repository

The objectives for this project are:

drop in replacement for Omron TL-Q5MC2 or PL-08N2 (you don't need to replace the toolhead), replacement of BLtouch probes
soldering not required
minimal adjustments required
be able to detect all the print surfaces
be as close to the hotend tip as possible
highly repeatable and accurate probes
less temperature variations
no melting of its parts
cheap to build
reuse spare parts if possible

Most of the Klicky probe users are using klipper, there are some macros in here that ease the probing process, by automating the attach, dock and use of the probe.

Some work has been developed to have the same functionality on RRF.

It can also be used with the automatic Z calibration klipper plugin to effectively calculate the Z offset from the probe and from the Z endstop if your printers supports a Z endstop triggered by the nozzle (like most Voron's do)

The inspiration for the Klicky Probe comes from the Quickdraw and the Euclid probe, it uses some concepts from each of the projects.

Updated instructions provided by StefanRaatz. oc_geek and TurBoxxs were also a great help in refining and testing the CAD files. Garrettwp provided the initial revised macro files. User richardjm revised the macro variables and added some functions. Mental created the initial macro and one of the first magnetically attached microswitch probes.

Without them, and some others this effort would not be in the current state, many thanks to them all.

Upgrading from an earlier version

If you are upgrading from an earlier version, check the klipper macros folder, it contains update instructions.

Klicky components

All the compatible printers require:

Toolhead mount (the thing that the probe attached to when it's being used)
Klicky probe (there are three versions, all are interchangeable and compatible, more information on the specific printer page), what actually is used to probe the bed
Probe dock (all the printers use the same)
Probe dock mount (what attaches to the printer to dock the probe when not in use)

The CAD with all the files is located Here

Common Klicky STL's (parts that are common to all the printers) are located here. Printer specific STL are in each printer directory.

The klipper macros are here, the RRF here.

Probe accuracy

The probe accuracy output is better than a range of 0.025mm (difference between highest and lowest), and a standard deviation of 0.01mm.

Print Settings

There are no need for supports, recommended settings are 4 perimeters/top/bottom, at least 23% infill, the STL's are already oriented, you only need to send them to the slicer.

Each printer family/version has it's own mounting options, Bill of Materials, assembly instructions and dock/attach setup.

General Bill of Materials (BOM)

Tools:

1.5mm Drill (optional)
Multimeter to check for Continuity
Super Glue
Soldering Iron for the heat inserts

Probe BOM:

1x microswitch (the omron D2F-5 or D2F-5L (removing the lever) is recommended), D2F-1 and similar sizes microswitch also work
2x M2x10 mm self tapping
some 6 mm x 3 mm magnets (it ranges from 8 to 10)
some m5 screws
some m3 screws
some m3 heat inserts
some m3 nuts
