I think I found the limit

This came up in a similar thread so I figured I’d address it here.

Part of determining the “limit” of how small I could cut involved making sure that “weeding” was practical. It involves more than just determining the minimum cut width to preserve the detail, but also making sure the cut goes thru cleanly enough to be able to remove the excess material.

It sounds simple enough, but as most owners know it’s not always 100% guaranteed that parts will drop out of a completed cut. Even with PG materials, there are variances in material density that can cause issues. While extracting other (much simpler) parts for this project, I had a whole piece (the center one in the previous image, in fact) give me a heck of a time. It was at one end of the sheet, so there was something different about the makeup of that material over on that side.

When trying to come up with settings that work reliably for something as detailed and complicated as this (the first piece I posted), and be able to extract the waste without damaging the design, you need to test and come up with settings that work.

As it happens, in this case, the width of the detail, cut using PG settings but with the upper layer of masking removed, meant that a lot of the scrap dropped out when lifting from the bed. The really fine stuff came out when tapping out on a hard surface after removing the back-side masking.

It takes a little practice to know what works for this kind of detail work, but it’s worth it if you like this kind of thing.
