Thanks for the suggestion, but brass and steel (which alloy?) aren’t the same. Wazer, on the one hand, informs us to go through an extensive process ($) for adding materials to the cutting library, which you then have to repeat at different thicknesses, and then, on the other hand, spotlights a user making brass jewelry and has in their website, brass listed as a material you can cut at different thicknesses. I would pay for a DLC-like upgrade to the cutting library.
I’m glad that works for you, but this isn’t my machine, so I would rather not set a precedent for users to use different material settings. Also, I’m sure the fact that they have a calibration procedure developed by the designers of the machine doesn’t mean you need … a calibration procedure.
