Hi,

Impressed by your work :)
Made a 100x100mm square using the internal design feature in the Shaper Origin:

1. Using original domino's resultet in exact size
2. Using the 43x12.7 domino's printed out from this site, resulted in 98x99mm. So that means it should be 43x12,82 (something like 1.693x0.505 inches). and btw, if the 44 is used instead of 43, it results in 1 mm wider domino, and still 1 mm too small domino.
   Seem like the dimentions of the domino's are both determinators.
   Can see that 42.995 and 2.672 is used by Heusserurs.

Hm. There's more than just the size of the dominoes embedded in that. There's also the spacing between.

The 98x99 mm metric is useful, though. I can adjust the page size without modifying other code, I think. I've updated the gist. Please validate with that.

Do you have a link to 'Heusserurs'?

https://github.com/heusserurs/ShapertapeGenerator and I think you are right with the horizontal distance between the domino’s and the source code is found her: <http://tcode.ch/shaper/> http://tcode.ch/shaper/

Hi,

I did test and got the same results using https://fordi.org/shaper-dots.svg. I looked at the web page source, and can see that the recent changes you made, is not reflected in https://fordi.org/shaper-dots.svg. Could you eventually setup a "https://fordi.org/TESTING-shaper-dots.svg" webpage?

I'd rather not put testing in prod. Can you just download the SVG file and drag it to your browser?

Nevermind. I've updated the gist's SVG and JSX to match what heusserurs is doing, and updated https://fordi.org/shaper-dots.svg

THX :)
Test: as usual 100x100 mm square, output 99x99mm. Printed on A4 Landscape.
