OK, I'll sort you something out tonight unless you want something specific like text and size.
Screen set will not have anything to do with it, we use a custom one anyway with everything we need on one screen.
Email me details of the cutters, included angle and tip flat as it alters the appearance on V carve files if not matching. When they match you get a sharp corner to the text, if incorrect you get an indented radii in each corner.

Just had a look at the code and it is indeed made up of thousands of lines of straight cuts.
I did a quick file in Illustrator then imported that into sheet-cam and with the same tool it now creates I/J arcs so in theory at least that file should cut a whole lot smoother I think.

Yes, many times this is the reason, the line thing instead of curves. I always magnify before generating path, to make sure all is smooth .
I would say also for fine engraving to have the Z0 using probing with the V bit itself is the best method. That, and knowing the exact tip size.

Yes, i always probe with the actual tool.
I tried cutting the Illustrator file tonight, yes it cut far smoother but it was generated as two paths which gave me a letter with an inverted V in the middle ;)
A settings issue, wrong font, wrong code generator, other problem?
Lots to learn here...

My CNC world consists of CAD - either Deltacad or Illustrator, CAM - SheetCam, CNC - Mach3
Apart from some free programs that i downloaded for messing about with that's about it.
Vectric V-Carve was about £400 I think - a lot of cash for something that is unlikely to bring cash in via sales I think.
