Started experimenting with living hinges using the Inkscape Living Hinge extension. I don’t understand how the Glowforge software decides on path cut order, but it appears to do each row one at a time, starting at the top of each line. I figured it would save some time if alternate cuts took place in the opposite direction, so I modified the extension to do that.
On a moderately sized 5"x5" hinge, it shaves off about 5%, about 45 seconds on a ~16 minute job. So it’s not a huge improvement, but it’s not nothing. If you’re doing super wide hinges, the time saving may be better.
You can try it here, just replace the existing living_hinge.py file in your extensions folder.
