I have a CNC machine that looks like this:
I have tried placing different types of surface (wooden plates) on the top, but it seems impossible to get perfectly flat piece of wood. I'd end up having 0.2m - 0.8mm differences in height, across the board, which resulted in deeper cuts and cutouts through the table itself.
I also have aluminium plates for that machine, which look like this:
However, when I place piece of MDF (for example) on top and try to clamp it, I still end up with 0.2mm differences at places.
Now, I am thinking of using double-sided tape across the whole length of MDF piece, hoping that will tie it to the aluminium plates properly.
But before I do that, I wanted to check what other people are doing, and how are they solving the problem of having 'perfectly flat surface table'.
Any ideas, comments and suggestion are more than welcome
Thanks.
