I have a control panel with a logo that is apparently a double nested extrusion. I created it myself and thought at the time I love this new feature.
I made a copy of the control panel to work on the next rev. and when I remove some of the lettering from Boss-Extrude2 suddenly the logo generates a "double nested extrusion" mssg. and the extrusion fails. IF I remove 1 line of lettering at a time, closing the sketch in between, the retrotec logo works fine until I delete "Input 240VAC...", that's where it fails.
I tried copying the logo to a separate sketch and the double nest doesn't carry over, have to do the lettering separately.
Aggravating because I frame letters frequently. I've attached both the original and the copy.
