Laser-cutting acrylic

I had a bit of a nightmare laser-cutting the fronts and tops for the coffee container. All i wanted to do is raster the logo so it kind of colours it in rather than cuts out.

This is my first raster attempt . Can bearly see it at all so i wanted it deeper. 

Here you can see it a bit better but still really faint.

These next few images above are my attempts of cutting this deeper one of them worked and there was a lot more attempts that i didn't photo. i was running out of acrylic and i think i nearly flipped out. I knew what i was doing just some of the million setting must of been wrong. 

I also had to change the design and make it a stencil chape otherwise it colour in the centre of the a' and between the t and s. 

I finally got it with my last few gaps on the acrylic i can't even tell you why these came out im sure i did this from the beginning. I am massively happy with the results although i think i have sprouted a few grey hairs because of it.
