I use the foam on the floor with a cheapo circular saw. It works great. You set the saw to cut a 1/4” into the foam. You get a decently clean cut on the sheet goods, and its safe, supports the workpiece and the cutoff, and it’s quick and easy to set up.

If I don’t need 1/16” or better accuracy, a decent aluminum straight edge and a Diablo blade on the cir saw does a fine job, otherwise I cut 1/2” oversize and clean up on my TS.

A small hint = cut the foam down an inch or two on length + width. That let’s you clamp the edge guide much easier than if the foam goes up right to the edge of the work.
