I'm experimenting on a scrap of corian and wanting to make a cookie stamp.
Or something I can roll the cookie dough onto and have it impress and cut the cookies.
I'm trying the stamp mode in the Trotec Job control and because my laser is only 30W, it's not going very deep.
So for multiple passes, do I want to periodically refocus or should I just do all passes at the original surface height of the corian?
I'm hoping to get at least a 3/16 deep pocket to indent the cookies but wondering if the laser beam spread as it gets deeper is going to ruin the image.
BTW, I tried HDPE first and it does not work... it bubbles up and stays warm for quite a while.
