Achieve precise, repeatable Z-probing with the CNC Voron TAP V2 — a premium, lightweight nozzle-contact probe developed by Chaoticlab (available via BIQU) for high-performance Voron 3D printers.

This fully CNC-machined aluminum probe uses a short MGNH7 linear rail and magnetic assembly, allowing the entire toolhead to move slightly when the nozzle touches the bed. An advanced OMRON EE-SX4320 transmissive photomicrosensor (0.3mm aperture) triggers reliably, delivering exceptional accuracy without traditional probe offset issues.

Key Features & Upgrades (V2):

Ultra-lightweight design at only 62g (without screws) — minimizes toolhead mass for better dynamics and Input Shaper results
No loss of Y-axis stroke or build volume — thickness matches Voron 2.4 R2 X-carriage
Upgraded 5-24V wide voltage support (improved from V1)
High-precision OMRON optical sensor for superior reliability and accuracy over contactless switches
Sturdy HIWIN linear guideways, steel limit nuts, and magnetic limit assembly
Excellent mechanical stability with 500-800g nozzle probing force

Thanks to Voron Design and Badnoob

We sincerely thank the Voron Design team for their open source project that enabled us to develop the CNC Voron Tap.We especially want to recognize Badnoob, creator of Voron Tap, for participating in the iterative R&D of the CNC Voron Tapand providing valuable feedback on our V2 version. Badnoob also aided in internalproduct testing to help us evaluate the performance and reliability of the CNC Voron Tap V2.

The openness and creative spirit exhibited by Voron Design and Badnoob have made tremendous contributions to
the 3D community. Chaoticlab will continue embracing these open source values to jointly advance 3D printing.

Why MGNH7?

Compared to MGNH9, MGNH7 is lighter and thinner. This allows us to minimize the burden on the extruder and avoid loss of Y Stroke. Meanwhile, MGNH7 offers the same sturdiness as MGNH9. We specifically chose reputable HIWIN linear guideways, designed steel limit nuts, and a magnetic limit assembly to maximize sturdy and reliable construction. This gives the CNC Voron Tap V2 excellent Input Shaper data.

The CNC Voron Tap V2.0 is built with MGN7H linear guideways, and the quality is very good.

V2: Transmissive Photomicrosensor with 0.3mm Wide Aperture
V1:Contactless Optical Microswitch

5-24V

Expanding the voltage range in the upgraded V2 to support 5-24V for flexibility.

The sensor of CNC Voron Tap V2 is OMRON EE-SX4320 transmissive photomicrosensor.

Feather Light

Weighing just 62g without screws, the incredibly lightweight bodywon't add noticeable mass to the toolhead, maintaining precesion.

The weight is only 65g, which will achiev no loss on Y-axis travel.

Maintaining the Original XY Stroke

Preserves full range motion and build capacity,letting you unleash your Voron's capabilities.

Build for Solid, Made for Ease

*When using the CNC VORON TAP V2 with the Carbon Fiber Tube Kit for Voron2.4 X-Axis (300)\ (350), an additional printed part is required to adjust the mounting position of the X-axis limit switch bracket. You can access the following link to obtain the print file:

Installation and Usage Notes

XY Stroke Influence

No XY adjustment needed - CNC VORON TAP V2 thickness similar to 2.4R2 X carriage.
MGN12H X-Axis Requirement

CNC VORON TAP V2 requires MGN12 X-Axis, not older MGN9.
CW2-Style Mounted Extruder

Replaces X-carriage and needs front screws like CW2.LGX/Galileo mounts are available.
Bed Mount Stability

500-800g nozzle force during probing. Ensure no bed motion as it reduces accuracy. Not recommended for Voron 1.8/Legacy/Switchwire.Compatibility Test: Firmly tap bed - movement means unsuitable.
Good Mechanical Condition

More precise than previous sensors. Fix known issues before installing.
