HI All
putting this out there in case somebody has a solution.
I current have a jig for engraving multiple coasters in one go…the jig has two alignment marks for the print and cut feature and 20 holes to engrave on
The issue i have is that the coasters aren’t EXACTLY round - they are roundish but not exactly round and not exactly the same size either
In my mind i have some facility to align the coasters around a the Centrepoint of the cutout for the engraving, however I’m not sure how to achieve this other than to eyeball it - which as we all know is hit and miss at best
Even using the camera is hit and miss because the camera is angled to the bed and seeing the "edge of the coaster (19mm thick) is somewhat difficult with the camera
so i wonder if anyone does something similar and how to acheive a desired outcome
@jkwilborn has a great template. The best thing about a template is that when it’s very nearly the same height as the workpiece the optical error caused by the difference in elevation disappears when you lower the bed to the new focal height.
In your case, you’ll probably have to pick some type or orientation … meaning if the objects are elongated, you might have to place it in the jig with some orientation…
I’d check out the center of the object and see if I could think of some reproducible cutout…
Generally what you need is two contact points… further apart the better…
Then you can easily (*) insert the coasters with their center point pretty nearly centered in the fixture, by eyeballing the part of the circles visible around their perimeter.
