Centroid KP-1 CNC Touch Probe with USB-C Connection

Centroid KP-1 CNC Touch Probe

The Centroid KP-1 CNC Touch Probe is a precision probing tool designed for setting part zero, locating features, measuring parts, finding bores and corners, and digitizing surfaces on compatible CNC machines. It is built around Centroid’s proven kinematic probe design and works with CNC12 probing and digitizing cycles.

The KP-1 is a strong upgrade for CNC users who want faster setups, more repeatable part location, and better measurement capability directly from the machine. Instead of manually touching off edges and surfaces, the probe allows the control software to detect contact and calculate positions automatically.

Why Choose the KP-1?

• Faster part setup: Use probing cycles to set part zeros, locate bores, find corners, and reference part features more efficiently.
• Built for CNC12 probing cycles: Designed to work with CNC12 Probing and Digitizing cycles on compatible Centroid control systems.
• Precision kinematic probe design: Uses kinematic seat technology for repeatable trigger behavior and accurate probing.
• High repeatability: The manual lists unidirectional repeatability at 0.0001 in / 2.54 microns.
• Visual LED status indicator: The internal LED shows green when ready and red when triggered, making setup and testing easier.
• USB-C probe connection: Uses a USB-C style connector on the probe body for the probe cable connection.
• 1/2 inch stainless steel mounting shank: Fits commonly available 1/2 inch tool holders.
• Patented concentric alignment: Allows spindle/tool holder/probe body runout adjustment for better probing accuracy.
• Useful for digitizing: Can be used to copy surfaces and shaped objects through compatible CNC12 digitizing functions.

What the KP-1 Helps You Do

• Set part zero positions
• Find reference positions
• Locate bores
• Find corners and edges
• Measure parts and features
• Digitize surfaces and shaped objects
• Improve setup repeatability
• Reduce manual touch-off time

Customer-Friendly Explanation

The KP-1 is used like a precision sensor in your CNC spindle. When the stylus touches a part, the probe sends a signal to the controller. The CNC control can then use that contact point to calculate part location, center positions, bore size, corners, and other important setup measurements.

This saves time and reduces guesswork during setup. It is especially useful for shops and builders who frequently change parts, need accurate work offsets, or want to use CNC12 probing and digitizing features.

Compatible Control Systems

• Centroid Acorn
• Centroid AcornSix
• Centroid Allin1DC
• Centroid Oak
• Centroid Hickory
• Other CNC controls with compatible probe input wiring

Important Setup Notes

• Requires compatible CNC software and probe input wiring.
• CNC12 version 5.24+ is listed in the manual for the KP-1 documentation.
• For CNC12 probing functionality, confirm your control license and software version support the probing cycles you plan to use.
• The USB-C connector must be fully seated into the probe body before use.
• Test the probe before every use to help prevent probe crashes.
• Do not exceed the listed overtravel limits.
• Probe alignment should be checked any time the probe is removed from the holder, the stylus is changed, the probe is moved to another machine, or the probe is dropped/shocked.
• Each stylus should be calibrated for pre-travel compensation for best measurement accuracy.

Care & Maintenance Notes

• Do not use compressed air to clean the probe.
• Do not submerge the probe or expose it to direct coolant washdown.
• Avoid excessive heat over 120°F / 50°C.
• Use only compatible cleaners on the polycarbonate body.
• Store the probe vertically with the nose pointing down.
• The KP-1 has no internal user-serviceable parts and should only be serviced by Centroid.

KP-1 Touch Probe Buying Guidance

Choose the Centroid KP-1 if you need a CNC touch probe for repeatable part setup, CNC12 probing cycles, bore and corner finding, feature measurement, and surface digitizing on a compatible Centroid control system. The KP-1 is best suited for users who already run, or plan to run, a Centroid CNC control such as Acorn, AcornSix, Oak, Hickory, or Allin1DC and want probing capability integrated into their CNC workflow.

Before ordering, confirm your control system, CNC12 software version, probing feature access, probe input wiring, and selected KP-1 cable option. The probe itself is only one part of the probing system; correct wiring, software setup, calibration, and safe test procedures are required for reliable operation.
