“Hey I made a small jar, but it’s not very round, do you think you can maka a lid for it still?”
Sometimes yoi have no choice but to accept the mission your spouse propose you
Let’s say it’s a great occasion to practice tracing shapes once again
I kinda like those quick “projects” where you just get exactly what you needed in under an hour of work…
Nothing really fancy or complicated, but the CNC is just “the right tool” to get them done
Using a scanner removes a lot of skew from the image that would be added by the camera lens.
If you use a camera for these kind of applications it works best if you go as far away from the object as possible and then zoom in as far as you can. Smaller focal lengths tend to perspective distortion, the longer the focal length the smaller the distortion (kinda).
As the scanner moves the head and takes one image per line directly perpendicular to the glass surface it is not subject to this kind of distortion and gives you a very easy way to get the true “topmost surface shape” you need to make your part fit.
