    Pull the belts off and check by hand to see if each axis runs smoothly with no binding and no "bumpy" spots. The K-40 machine should be fairly close to the same as Full Spectrum's 4th gen hobby...

    MDF spoilboard is one of the more cost effective ways to go. Set up braces under the table to hold it on. Cut a piece of 3/4" MDF (see if your local supplier can get you the low density type) and...

    You had turned layer '0' off too. Don't bother turning off Defpoints. It won't plot. You can set it to a really dark color so it's not intrusive in your view.
