CARTO Ballbar Connect
A snapshot of machine tool health
CARTO Ballbar Connect is a unique smartphone app that allows users with less experience to run ballbar tests quickly, easily and with confidence. It gives a snapshot of machine tool performance by running a simple 3D Check test sequence and presenting results in a single quantitative and visual way.
The CARTO Ballbar Connect app uses on-machine macros, a set of instructions written to automate complex and repetitive tasks. They remove the need for extensive G-code knowledge and allow users to customise a single-line machine instruction for configuring and running a QC20 ballbar test.
Key benefits
Fully connected - CARTO Ballbar Connect wirelessly connects to the QC20 ballbar for a streamlined flow of information, maximising efficiency.
Enhanced understanding - Data collected by the CARTO Ballbar Connect app will increase your understanding of your machine's health.
Easy to use - Tips and helpful animations are available at any time, making it accessible for users of all experience levels.
Simple test - 3D Check runs a single volumetric test sequence.
Intuitive results - Spherical deviation provides a comparable measure of machine performance.
Simple test process
The 3D Check test sequence moves the ballbar to twenty-nine target points around a spherical volume, measuring the radius at each point. Using a single test sequence to capture static data for the entire sphere significantly reduces both the measurement time and user interaction required with the QC20 ballbar. Simplified single-line commands remove the need for extensive G-code knowledge.
Test set-up
CARTO Ballbar Connect makes it easier to enter measurement parameters and refine the testing process. This streamlines test set-ups and makes ballbar testing accessible to all users.
In-app help
CARTO Ballbar Connect is developed with users in mind. The intuitive user interface and in-app animations guide users, helping to build confidence in using the QC20 ballbar as a machine health tool.


Intuitive results
Once the 3D Check test sequence is complete, test results of all twenty-nine points in the sphere are presented in a single illustration, giving a clear snapshot of the machine's volumetric positioning performance and overall machine health.
The spherical deviation is calculated as the difference between the maximum and minimum radial readings of those twenty-nine points, and this provides a clear and simple output, allowing 3D Check to work as a 'go/no-go gauge' for confirming machine health.
By monitoring these snapshots, users can easily identify significant changes or drift over time, and can schedule preventative maintenance.

What is the QC20 ballbar?
Renishaw's QC20 ballbar delivers the fastest and most efficient health checks for machine tool performance. It is a highly accurate, telescopic linear sensor tool that allows you to identify and diagnose error sources, minimise reactive maintenance and concentrate on valuable preventative measures.
How does the QC20 ballbar work with CARTO Ballbar Connect?
Combining the Renishaw QC20 ballbar with the CARTO Ballbar Connect app simplifies the testing process. CARTO Ballbar Connect uses the 3D Check test sequence to produce a single quantitative result and graphic so users can easily assess the machine's geometric positioning performance. With in-app guidance throughout, users are supported at every stage of the process.
