I made a special version of my MazeMaker program that is hopefully suited for most sand tables.
For this special application I removed the demo limitations, that means the program is free to use
To enter the sand table mode, set the “Channel Wall” parameter to zero (this would make no sense for machined mazes). But please take the time to look over the included guide document (it is not that long) to understand the options, especially section 13. for the sand table.

and keep in mind this is kind of a beta. I tested it a bit on my own new sand table and it works quite well. Unzip the file somewhere (harddrive or even USB stick) and run the .exe file. No specific “installation” required. To remove the software, delete the folder. No “uninstall” required as well.
Depending on your controller you may have to edit out the “G10” lines in the beginning of the program that I use to home the axes. The g-code file output is a .tap but obviously you can rename it anything you like (.txt, .nc, .gcode etc.)
For mazes with image boundaries it looks best if the sand table is cleared first with an even line pattern. For square full size mazes of the entire table it does not really matter.
Set the start point to x-cell=1 and y-cell=1 (lower left corner , is actually x=0 and y=0) to avoid a start line across the table. The ball will also return to this point along the maze when finished. If your zero is in the center, specify x/y offset (check the gcode).
Let me know if something does not work as expected. Please let me also know if it does work and if you like it (or not) …
