Components

Here are some of the components used in Centroid CNC controls from 1993 to present. Click on the pictures for more detailed information and larger images.

These pages are intended to help you identify the components in your control, and to help you become familiar with their features, variations, and in some cases troubleshooting methods.

Replacements are available for nearly all of these parts. Contact me for pricing and availability.
