    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...

    VFD Wiring

    What horsepower is your lathe? The unit from Automation direct is probably sized on the small size, a size or 2 bigger might work better,. My employer sells WEG so some of what I am saying comes from some of the training I have been through. Depending on use, light, Standard or Heavy duty -...

    Upscaled Elmer's #5 as an IC?

    Can Anyone Identify This Engine?

    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...

    Calibration Question

    Unless you can say what you expect from "calibration" it is hard to justify anything. Is the machine not performing properly in any way? 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...
