Centroid CNC control sales, service, training and support
Centroid control serial numbers are generally 4-digit, 5-digit or 6-digit numbers. For many years it was conventional to prefix the serial number with the letter "K" for mill controls, "T" for lathe controls, "M" for Magnum routers, and "A" for Ajax kits. However, the letters are optional, as the numbers fall in unique series.
The serial number is generally on a black-and-silver tag. If you have a factory console (such as an M400 or M15), then the serial number tag will be on the back or side of the console. If you have a handheld jog panel pendant (such as with an M39), then the serial number tag will be on the back of the jog panel pendant. If you have a factory-wired control cabinet, then a serial number tag will also be on the door of the cabinet.
If you have an OEM board-level control (e.g. Revolution mill or Magnum/Phoenix router), or you have a board-level retrofit kit, or you have a DIY kit (e.g. Ajax), then you might not have a serial number tag at all. If you are lucky, you can find the serial number among your service documentation, or on a sheet of software unlock codes from Centroid.

See the Field Guide for more extensive descriptions and history of the various control models.
There was some crossover between mill and lathe designations. A few T39 lathe controls were assigned 3000-series numbers; a small number of T15 lathe controls were assigned 4000-series numbers; and dealers sometimes converted mill controls for lathe use or vice versa, in the field.
Some 1000-series board level controls -- mostly Revolutions, but also some built by Tryax Associates in the UK -- had multiple controls grouped under one 4-digit number. For example, 1339B-1, 1339B-2, 1339B-3 and 1339B-4.
Router tables, water jets, punch presses and similar machines usually use mill controls.
Cylindrical grinders and similar machines generally use lathe controls.
