Ortur LM 2 cutting 1.5 balsa wood

I am cutting a design out of an 8 x 12 sheet and the corner is curled up. I have air assist. Tried taping it down but not holding. Would weights or spray glue help or even a good idea?

It will help. I use 10mm magnets and position them with the camera so as to make sure I do not have any in the path of the laser. Weights, double sided tape, repositionable spray glues (not my first choice for laser though) all work too.

I also read somewhere to use masking tape over image area so when cutting the burn marks are on the masking tape and not on the wood.
