Suggestion for non-heated platform

I have a suggestion for both the CNC and laser platforms.

Please include a high-precision measurement scale on the platform. Not just a sticker (though that would be good too), but actually on the board.

A Cartesian plane for X/Y axis, with diagonals marking the center. Short (just a - ) marks for the millimeters, with longer marks for every 0.5cm. That would help positioning a LOT
