I think it would also be better for diodes that have a rectangular beam, and so have a different kerf on the vertical and horizontal axis. My test doesn’t account for that.
HaHa! Don’t tell us, tell the Programmers!
Better would be if the manufacturers fixed the laser modules. The eye doctor can write a script for glasses to correct astigmatism, right?

bah! just rotate 90deg and send it!
Yeah, honestly I don’t understand why the diode manufacturers don’t just put the beam source on a 45 degree angle, that would solve the issue for most users most of the time.

Yeah, but then they could not make those small-dot claims in advertising.
At any time they could start mounting the diodes rotated 45° in the support frame. Of course, only 10w and up lasers would benefit. Where there are 3 diodes, #2 & #3 could be rotated 30° & 60° (or something like that).

How do you get that font
Which font is ‘that’ font you mention? The fonts used in LightBurn are the system fonts.

The font that is used in the kerf offset test. The ones that say Box Joints Part A and Box Joints Part B
I believe I got it here: SHX Font Collection
If you’ve never used SHX fonts before, they’re a bit different to system fonts:
Reddit has been hosting a discussion about kerf and the particular sub does not allow links or attachments. This forum doesn’t attach a .SVG file as such and presents it as an image and also doesn’t allow .ZIP files.
Some laser users are “handicapped” by not having LightBurn, so I’m providing the SVG version of
the file on my Dropbox.
EDIT: Link removed due to operator error, drain bamage and whatever else one might want to call it. Later post is providing the correct result.
Not sure what that was, but it was not SVG.
You can upload the SVG file, it displays as an image, and downloads as an SVG file.
Like this:
Now, admittedly, it has a rather unpleasant UUID-ish file name, but I think that came from Dropbox.
that’s what I had as a result of my first attempt but the download was rubbish. Perhaps the file I had was rubbish from the start. I’ll purge the link and the file and let everyone be satisfied with your contribution.
Does now, thanks for fixing it.
Had some confusion. I think it would be wise to explain where the value of 40 arises.
Instead of saying divide by 40, maybe you should try to post it as (2 x 20) in the denominator, indicating you’re dividing by not only 20, number of cuts, but also by 2.
Here’s link maybe you can assist with.. someone using it has computational issues. He’s getting a value of about 50 microns for an led laser, where the documentation for that laser claims a spot size of 200 microns.
You help is appreciated…
