The Voron Tap upgrade is the latest release from the Voron Design team featuring:

  • Physical Nozzle Probing
  • Drop in upgrade to existing Voron 2 and Trident 3D printers (mgn12 x-rail required)
  • Significantly more accurate than previous spec inductive sensors
a33e9d33 voron tap upgrade kit


Tap is a nozzle-based z-probe for the V2 and Trident printer designs. The entire toolhead moves to trigger an optical switch. Tap offers many advantages over other z-probes; Here are a few examples:


A well constructed Tap, when in service on a well-constructed printer, will be able to measure your Z position reliably with a precision of 0.4 µm (0.0004 mm). This precision will help you better use and maintain your printer.


For consistent probing temperatures, Tap uses a single ‘activate_gcode’ macro in the [probe] config. Tap is always ready to probe and requires no docking or undocking moves.


Tap uses light to detect movement and will never wear out. The sensor in Tap is rated to operate at 70C to 100C and will not degrade over time the
way a contact switch or inductive probe can. Even if you brought your chamber temperature to 100C, it will accurately and reliably record your printer melting (assuming you printed in ABS).We tested dozens of printers and thousands of print hours. Hundreds of PIF quality kits were printed using
Tap. Some test printers had over 1,000,000 probe cycles to test durability.


Tap can measure any securely mounted build surface. Print on Glass, Garolite, Alumina, Moon dust…it no longer matters. Textured plates are ideal for Tap, but adhesive PEI sheets may also be used. Tap is unaffected by beds with magnetic fluctuations (note: magnets may affect the build surface Tap is sensing, such as pulling the plate tighter over the magnet). Once Tap is setup, you should not need to recalibrate after changing nozzles or build plates.


There is no need for a separate Z endstop. Once the offset is configured, it will hold without appreciable drift. It is normal to need slightly different offsets when switching between filament types.

About Unique Prints Shop

When we bought our first off the shelf 3D Printer in 2019, like many others, it wasn’t without its shortfalls. While being a great machine to begin our 3D printing journey on, it required immediate fixes and several replacement parts to be its best.

Then we discovered the Voron!… A do-it-yourself, source-it-yourself, spaceship of a printer designed by the team at Voron Design for the hobbyist and enthusiast.

While printing the required parts and combing through the required components to be purchased, we realised there was a gap in the market for 3D printer supplies in Australia.

And…Unique Prints was born!

Voron Legacy (1)
We aim to take the guesswork out of buying 3D printer parts and components

We love 3D printing because of the unique nature of Voron design philosophy and there’s nothing better than printing from a machine you’ve brought to life.

Unique Prints get it because we’ve been there.

We understood the challenge should be in the build and dialling in that perfect print quality at warp speeds. It should not be in the headache of trying to find the quality parts and components – so we decided to do something about it.

Resourcing printer supplies from reputable suppliers within Australia and around the world – we aim to take the guesswork out of 3D printer parts and components for 3D Printer enthusiasts like ourselves.

Thank you for taking the time to browse our website and be sure to reach out to us if we can help in any way!
