One of my struggles has been to understand what happens to the effective laser power applied to materials when speed and power are adjusted.
Its too unreliable (for me) to just slow things down or speed up; Too slow can equal extra soot marks or even fire, speed up usually means an incomplete job…
Yes, I often add in an extra pass or two at the end of a job to finish off. Time consuming.
I needed a guide (based on a test-cut / etch that worked) that would extrapolate to slower - less passes or faster - more passes to tweak things reliably.
I came up with the following on a spreadsheet. It seems to “work”.
If someone can correct my physics and the “Power Applied” formula, I would appreciate it.
The spreadsheet itself wouldn’t import here, so I did it in text bits.
“A” is the Power column, B is Speed, D is number of passses…
I have only tried this on 100% power so far.
