DIY Laser bed problems

Interesting videos, i would think that if you use air assist (i do) that it would blow the fumes through the bed. In the video it looked like he had air assist but i don’t know if he used it or not.

It is a dutch company but they have them here (1300x900mm)

I also know a guy who can cut 1mm sheet steel so i will remake the bed i have now with the steel and hopefully that should fix all my problems.

Thanks for the help!
