Nicely done. I think you can improve your precision by calibrating the backlash on your machine. I notice that your circles are not quite round, and backlash calibration can fix that. Then it will be even better! You might also check your "small circle speed limit". If you do, I'd try to remember to use a lower min power than the max power (in other words, don't use the same value for both).

Yes for sure, all is Handmade.
First done in Corel the dxf file and then cut.

"Handmade by Roschi" is the Brand of my Wife :-)

Hello,

the holes are round. Maybe it is a bit from the Foto.
BUt even i am interested what you mean with Circle calibration.
The Cut is done like in the attached picture.

Hello,
i tried this , and without any changed settings i get this result.
The corners seams not so "sharp" then in the Picture from the website, but they are in line i think.
Or did you see any failures?
