I would not dare call you picky. The other part I have no comment. ;

If you look at something like Vectric's V-carve Pro it does the faster
no-lift case. I suspect the high-end Aspire tool does the same since they
are based on the same code base. For something like an A they don't even
lift to go back a little to get to the cross bar. And its geared towards
wood

I was just about to suggest that. Hershey_fast and
Hershey_unidirectional maybe?

Lasers engrave too, and should produce the same results in both of your
examples, although much quicker in the first example.
Even on a CNC router or a mill, there is a large amount of variation in
the results depending on spindle speed, cutter diameter, grain structure
and other physical prope
Hi all,
While porting the Hershey fonts for engraving it occurred to me that
they are very heavy in pen-up/down movements because many strokes are
partials. There is plenty of room for optimization, reducing the rapid
moves by about 30%, but that means that engraving is not done in a
consistent di
