I purchased an emblaser 2 to cut some holes in PET caps(basically coke caps).
I made a jig from black 18mm concrete form ply as the base and white 3mm core flute for the jig bit.
Settings: Power 100%/Speed 2.2mm/sec/ Air assist speed 77%/ Base suppoprt height 37mm (concrete form ply 18.3mm+ Blue cap 18.6mm) thickness of material:1.5mm polyprop ( blue cap). and 7 passes.
The hole is not a good finish.
Should it take 7 passes to cut 1.5mm poly-prop plastic?
Seems far too long but this is my first time using this laser.
