I have a 3D printer that I built using CD-ROM drives. It's all set and ready to go but when I generate
.obj files my G-code sender program cannot load it. I have found that Slic3r will export the
.stl into G-code but it has the option of changing the G-code flavour, or firmware.
My machine is running from an Arduino Uno with Grbl v0.8.
So the question is, which firmware setting would be appropriate for my machine that would require the least amount of editing before I can print?
