Hello I'm an architecture masters student, I've been working on a desktop cnc mill(10x8x3) and attempting to keep it arduino controlled, though this is making me bang my head against the wall.
anyhow, I discovered this firmware here
it was written/released in may 2010, and hasn't been updated since, no word from the author, but it's the most friendly I've found and way easier for me to setup and use than the reprap stuff, plus he's implemented a really nice interface that draws gcode in processing. His acceleration seems way smoother than reprap and I can get my steppers moving faster, 60 ipm.
The problem lies in the fact that it seems he has not implemented G2 and G3 gcodes, for arcs/circles. Thats kind of a problem for most gcode I generate at school.
SO, I'm looking for a bit of guidance, I'm not a programmer, but I wanted to learn anyway, so is there somewhere I can be pointed to checkout how implement this within the hydra 1.4 firmware?
I guess basic theory or other examples?
