Laser cutting

This is my laser cut after so many testing and making sure that the laser cuts all the way through the material

but it did not! it only cut some parts of my file fully and the rest of my file remained as a deep etching which made me do it all by hand ( a painfull process and the result wasn't as clean finished).

That's how painfull it was to seprate the bits that didnt cut through. I should mention that I could not afford buying and cutting the file again. that's why I did this.
