I am working on a custom order where there is a lot of engraving. and I have been now seeing this engraving issue come up not only with the birch plywood (1/8") I am using but also with the (1/8") acrylic I am using. It seems to engrave fine for some portions but does not fully engrave for the rest as you can see in the photos. The top engraving “Holidays From Fisher” are perfectly engraved, but the “happy” and “architects” is not fully engraved.
I have cleaned my machine several times and did a deep clean, but still gettinng the same results. Any thoughts?
