A little something for the forum - Rayco Style 36x36 CMM Fixture location Grid

2026-09-22T12:52:57Z

I created a .Net program for using a 36x36 Rayco Plate with 1.00" spacing for Grid location of fixturing on a CMM. (Grid size is automated in the code).

If you have a smaller plate, just use the grid locations for the size plate you have.

I am attaching the program for users of this forum in 7zip format to use as needed.

You will need ".Net Desktop Runtime 10.0.11 (X64)" installed, or the software will attempt to install during the software install process.

I had zero issues installing on Calypso v2016, v2017 and v2022 with this install other than you may need Admin rights.

This allows me to add a part number (I use my CMM program name) and identify the locations on the Rayco plate.

The Grid viewing area works on most displays from 15.6 inch (laptop) thru 27 inch PC monitors (as tested) and should have no issues on larger displays.

Adding a part number and locations is very easy.

1. Enter a part number in the "Enter Part number/CMM Program Name" field and select "Add/Update". If the part number doesn't exist it will be added, if it exists it will be updated. Grid locations are not forced at this time, so make sure you add Grid locations, if not add them later and then it will update.

2. Enter grid locations in the "Locations (comma-separated)" field (See image Rayco Style 36x36 Grid - Fixture Location - Selection Shown.jpg)

2a. You can use as many grid locations as needed as long as they are comma-separated.

3. The grid will highlight the locations in BLUE and highlight the letter/numeric locations in RED.

4. You can remove part numbers by selecting the part number in the "Part Number/CMM Program Name" list and then selecting the "Remove" button.. (Currently one removal at a time).

5. You can export the list in a ".json" format (basically a text file.

6. You can import the list in any installation location with a known json file.

7. For that savvy programmer, the .json file can be edited manually as well and then imported. The export/Import location is tied to the PC user, example:

"C:\Users\<user name>\Documents\CMM1InchFixtureGridLayout".

8. Upon closing the app, you will be prompted to save the current part list, Yes, No or Cancel. Yes will save the list (User interaction required), No, (app simply closes) or Cancel (App stays open).

Feedback from users of the forum is always accepted.

If anyone wants a copy of the Visual Studio Solution, message me with the request and your email address. The conversion to a Metric grid would be pretty easy in "FixtureBoardControl.vb" code.
