Surfacing the Wasteboard on Your Longmill

Learn how to surface your wasteboard of your LongMill. We’ll be covering the basic technique on surfacing that can be applied to wasteboards as well as other materials.

Why surface your wasteboard?:

Surfacing your wasteboard helps level the surface in relation to your machine. This means that if you have bumps or uneven surfaces on your wasteboard, or if your wasteboard is higher on one side that the other, surfacing will even out and flatten the board.
Cleans off old marks and scars, leaving you with a new, clean surface to glue, clamp, and mount your workpiece.

What tool should I use?

Technically, any flat end mill or bit can work for this application. However, using a wider bit can speed up the process. In the video we are using a 22mm surfacing bit.

Generating the code:
If you want to use the premade g-code, find it here:

I used a gcode generator from INTUWiz (http://www.intuwiz.com/plane.html#.Xi.... Here are the settings I used for my 30x30:

The center of the coordinates is in a point: 1
Side a: 762
Side b: 762
Tool diameter: 22
Y overlap percentage: 45
Total depth of cutting: 1
Depth of cutting per pass: 1
Feed rate (X,Y G00): 2000
Feedrate (X,Y, G01): 2000
Feedrate( Z G00): 500
Feedrate(Z G01): 500

You can also use a different program if you want and cut a shallow pocket of the size you need.
