SM350 Laser and slightly warped stock

Snapmaker 2.0

My Baltic birch ply is warping. About 1/2" over a 12" span.

I’m not seeing how to clamp it to the surface of the laser bed. I don’t see a way to put a big weight on it since the laser flies so close to the bed.
The warp isn’t enough to bother my project, and my project is big enough that I only have about 20mm on one edge of the sheet that’s unused.

Using painters tape could be a solution for fixing the work piece :thinking:.

If you don’t bother about potential scorch marks on your CNC wasteboard, I find that sometimes the better choice to fix workpieces for laser (instead of the laser bed). With its threads, you have very solid options for pinning down a workpiece.
