FWIW, looking through the recommended settings for Cermark, I see this at the top:
These settings are designed to help guide the user to the optimum parameters as quickly as possible. Please note that there will be variations in substrate finish and between different brands of laser. It may still be necessary to perform further refinement of settings to achieve the desired mark.
Guide. Quickly. Variation. Different brands. Refinement.
I can commiserate with translating the speed settings over. It takes a few seconds to do.
But the reality is that you’re almost assuredly going to have to test anyways. I’d say the good thing about using a product like cermark is that you can test right on the product itself, no? Either, A. Have delivered too much power and vaporized the product leaving no permanent mark, B. Nailed the power and speed and have a good, permanent mark, or C. not going to have applied enough power and leaving no permanent mark.
I can understand gripes and concerns relating to alignment, some of the stuck on focusing/scanning issues, etc. but I can’t really get behind something like having to test on materials… perhaps that added nothing to the convo.
The flipside to the comment above about “if I have a complaint about something and so do you, then comment. If no one else does, then the forum stays short,” I’d like to imagine they’d like to hear various viewpoints on a topic at hand. What may be a dislike for you, may not be an issue or even advantageous on my end. Point being, why would they want to hear from people with only a singular viewpoint?
