So I’ve had my machine for quite awhile, I haven’t had any issues previously. The only issue I am currently experience is with engraving letters. As seen in the pics below I can’t for the life of me get crisp lettering. I am currently using the Amana 45624-K. I’ve used this bit for plenty of other projects and have had no issues.
V-bits don’t come to an infinitely small point, but the software calculates the toolpaths as if they do. Raise your zero 0.2mm and try again. I posted a little spreadsheet calculator to get the Z it IF you know the diameter of the flat, but I think a quick test file with some text and a small rectangle would get you there quickly. With a quality but like that, I’d assume the angle is as advertised, but that can cause a similar issue.
Everything else is visually more forgiving. A V-carved duck probably still looks like a pretty good duck if your depth is slightly off. Text is something that we know exactly how it should and shouldn’t look.
