New here and wanting to build a CNC laser cutter machine

[Gravatel]

I don't think I'd need an oscillating knife as the foam isn't very dense.

It's the soft type like this 1600x900 150w co2 laser cutting out Polyurethane foam by HPC Laser LTD - YouTube just 110m thick.

Cheers!

I don't think you have a hope of finding a laser that will cut 110mm deep at a reasonable price, and you certainly will not Knife-cut foam that deep without some form of vibration/oscilation. I think that hot wire cutting will do it though. That's my opinion anyway. I do not mean to be negative, but realistic. Good luck with whatever you decide. G.

hi gravatel, did you see the end of the oscillating knife vid? I only ask as it shows the guys pulling the cut shapes out and the foam looks pretty flexible and not very dense?

It is also very thin - nothing like 110mm. G.
