Need help with laser cutting acrylic

[Nickhofen]

Ok that's the problem, you have to raise the parts you cut away from bed, because the beam reflect on the bed and melt or burn the material you cut.
You have to buy or make something like that !

Make a search on the web , you can buy the materials and make one on your own. Usually people use spikes like these.
