Voron Tap

PLEASE READ ENTIRE LISTING

There are 4 versions of the OptoTap PCB:

v1 5v and v2 5v-24v, both released in 2022 and v1.3 5v and v2.4 5v-24v, both released in March, 2023.

v1 5v is just as good as V1.3 5v.

v2 5-24v may set your house on fire, while v2.4 5-24v has, so far, started zero house fires.

Information on the kit may be found on the Voron GitHub Tap repo. Here's the intro from the manual:

INTRODUCTION: WELCOME TO TAP

WHAT IS TAP?

Tap is a nozzle-based z-probe for the Voron 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:

EXTREME PRECISION

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.

ANY BUILD SURFACE, CHANGE AT WILL

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.

VORON DURABILITY, HIGH TEMPERATURE OPERATIONS

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.

NO COMPLICATED MACROS

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.

Z ENDSTOP ELIMINATION

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.

CRASH PROTECTION

With Tap installed, the nozzle and bed are protected from minor crashes (such as accidentally setting your Z to 1 mm below the build surface
