Cutting sticky back 2 mm foam

Working on a paper airplane launcher - so needed to cut some thin stickyback foam from the dollar store to dampen the blows.
Pro model - used speed 150 power 20 - 1 pass - thickness .04" Seems to work fine with the paper side up or down.
Anyone has other notes on foam settings- please post - would love to get a database of sorts for this type of material. Assuming we want to use the least amount of power so edges are clean. I have had no need to engrave yet - would be interested in some ideas about settings people have had success with.

Hi there,
Just careful with foam as it can be very toxic once it’s in contact with the laser!
Always make sure to check before cutting it! :slight_smile:

Agreed, that is why we are looking to use the lowest power so it just makes it through I assume. I vent outside - waiting for the filter I ordered a few years ago - but I will still vent outside. When I cut plywood I usually leave the room and let it vent outside for some time before I return to the room as well, not sure what the rub is with the glue…

I’m prototyping - so don’t use it that much - the foam parts are very small - not sure I would do any large cutting projects - and especially engraving - not sure how that works either - agree that it is the invisible fumes that are bad for you! (although the smoke from a forest fire is also bad… - we had that last summer)

My goto for settings is this Google Sheet. It has a few foam options - feel free to add more!

Amazing, no more scratching my head!! - thanks Dierdrebeth!
