Tips for using the laser cutter to do papercraft / pepakura:
- There are a few ways to signify where to place the folds:
- In Inkscape, use Extensions > Modify Path > Convert to Dashes to cut perforations.
- Heavy cardstock can be engraved using very low power settings
- When printing, set the frequency to <100. The "frequency" setting is the number of pulses per inch. Using a very low number results in normal lines being cut as perforations instead. You will then cut in two passes, first cutting the perforations, then starting over and making the outside cuts.
Advice for aligning the laser-cutter to a texture that you've printed with a normal printer:
- Use the laser cutter to cut a jig.
This allows for more precise alignment, compared to using the rails on the side of the print bed.
- I'm pretty sure no printer has 100% accurate positioning when it prints. Even professional printers have to deal with registration problems, and have a bleed area, and crop marks. Ideas to accommodate this mis-positioning of paper when being printed: (note: I haven't tried any of these yet)
- After printing out the texture, put it in a scanner, and compare the page corners to 2+ registration marks that were printed along with the texture. Then shift the laser-cutter pattern to accommodate the misalignment.
