You can use 3rd party tool-touch off devices as well as probes with the Centroid control. You will still need to purchase the Automatic Tool Measurement software as well as the Probing software for that particular system. Please contact Centroid Tech Support at
[email protected] and provide them with your control serial number or a current report from your system. They will be able to provide you with a DEMO code so that you can use those items to test with and if you like the results then you can call them to purchase those features. I would also recommend looking at their DP4 and TT1B manuals to get the correct wiring and setup information.
