    CNC controller

    Poor GCode usage is not the only way to do it, but cheap systems use the many many line segment approach because it requires much less intelligence in the programing. Gcode is still limited to arcs in a plane, and the plane must be selected. The normal defalt is the XY-Plane. Spirals are...

    Glow engine

    Don't go to small on your first one. A slightly larger engine is a bit more tolerant on tolerances. You might take a look at the .60 size 2 stroke that I loaded to the download section a few years back. Okay, now that I look around, where did the downloads go??? Or is it me??? If you would...

Does it not cut to the proper size in one axis, or both axis? Most of this is just setting up some sample cuts and then taking measurements. For example - cut...
