When I set a cut to take multiple passes, I’m guessing the focus of the laser doesn’t change. I’m thinking there ought to be an option to make it do this. It should step down a distance equal to the original height divided by the number of passes. So if I start with a material thickness of 30mm and I specify 3 passes, the first pass focus would be 30mm, the second would be 20mm and the third would be 10mm. As the cut goes deeper in to the material, the focus follows (or approximates would be more correct) the depth of the cut instead of always staying at the top of the cut.
I think this would give me a more uniform cut from top to bottom in soft materials like foam… does this make sense? I can manually simulate this I guess. But if it’s a dumb idea, I’d rather someone say so, so I don’t waste my time.
