I have recently purchased a F1 Ultra and am trying to engrave part numbers on steel to a depth where they are still legible after powder coating. This lead to really 2 issues. I am currently trying to “score” the Arial Black font with multiple passes to achieve some depth. At 100% power with IR at 100 m/s I am able to achieve some results around 5 passes +. The issue is that scoring produces such narrow lines they will easily fill with paint regardless of depth. I tried using a small outline offset of .1 to try make the lines wider but the offset only works on the outside of letters and numbers insides of A,B,0,8. Any help with these issues would be greatly appreciated.
