How on earth does everyone keep ply (cardboard etc) flat?????
Just getting into my emblaser (just arrived a couple weeks ago), and managed to get it all working beautifully. The biggest problem I've found is there's no such thing as a flat material!
The focus seems to rely heavily on the material being the right distance from the laser, so how does everyone deal with the slight warpage in ply?
I've given up on cardboard for test cuts, it's warped enough that ply takes just as long to cut through.
