Inkscape basic Circle: Wonky path? #10

Open Sarah-C opened 2 years ago

Hi!

Great extension - I'm using it for cutting out IR filters to the right shape. Using the slowest 70, and brightest 255 settings, I only need 6 passes just using the low power L1! (rather than around 15 with the app)

I've noticed something... my circular filters are a little wonky... about a1.5mm wiggle around the origin. Nothing bad for my filters, but may cause issues for others?

Windows 10. Reproducing the issue: 1 : I drew a 23mm x 23mm circle in Inkscape 1.2
2: Drop down menu: "Path" / "Object to Path".
3: Extensions: LaserPecker.
4: Enter 80 for speed, and 255 for power, and click "Apply".

The resulting cut out shape has a slight flat side around the perimeter of the circle, which caused me to try looking on the NCViewer page. It MIGHT be that my LaserPecker stepper motors are a bit loose, and the following observation is unrelated, but in case it is I've posted the results below:

This is what the shape looks like in the G-Code viewer. The circle looks a little faceted, but also includes what looks to be a steady increasing radius!

This Isn't how the IR filter looks! It's MUCH more subtle in the real cut out! Hence why I think my stepper motors may be dodgy.

Any feedback is welcome!
