Using the lasercutter is a bit of a trial and error process, so it's important to record any settings and tricks you came across. Plus it's always good to show off your new toys. With that in mind, here's a page for anyone to stick up photos and descriptions of what they've made.

Hole Gauge:

Power: Engrave @ 20%, Cut @45%. Material is 3mm clear acrylic.

This was derived from this part on Thingiverse. Very handy for knowing exactly how large a hole is produced for a given input size. In most cases the laser thickness ('kerf') is negligible, but it's good to check.

There was a bit of fiddling needed to get the DXF imported into NewlyDraw succesfully. The trick was to select everything and do Object-->'Convert to Path', before exporting.

R3becca's Brass (Acrylic) Knuckles:

After a few prototypes in ~3mm acrylic I pushed Robots and Dinosaurs new laser cutter to it's limits with a custom design cut into 20mm acrylic. Many many passes of the laser along the same path were required but eventually it cut through. This creation was purely to experiment with thick acrylic and gain experience with the design process when using the laser cutter. This object will not be sold or used in anger, ie; it's art. :)
