I've been working on my first project - a 80 mm x 80 mm x40 mm box. Here are a few parts cut and fit after a little sanding. Machine is working well so far. My feed rate was set to 900mm/s. Currently i'm only running on a 12v power supply. I'll upgrade to the 24v over the weekend.
My tool chain and workflow is to first design the parts in inkscape (OS is linux), then export to SVG. Import into Carbide Create (running in Wine) and generate the tool paths. Finally, move the files to an old cell phone and use Grbl Controller as the gcode sender.
