Maslow CNC Router

The Maslow CNC was built by Fox.Build members to enable cutting projects too large to make in the X-Carve.

    Important safety information.

    • Wear Safety Glasses
    • Turn on the air filter when cutting
    • Breathing masks are available and encouraged

    Getting Started

    • The Maslow is really similar to the X-carve, it just handles a bigger work area.
    • It takes Gcode in the form of a .nc file.
    • This Gcode can be made by MakerCAM or any other CAD to CAM program that creates Gcode.
    • Maker cam requires a SVG file and outputs the .nc gcode file. Here is a great description of how to do it.
    • Other ways to make the gcode can be found here.
    • I have been using Kiri:Moto as an application in Onshape. It is great for waterline cuts but the pocketing seems to require facing which takes forever. The upside is I just import the part I want to cut from Onshape and start setting it up.
    • Once you have your .nc gcode file you are ready to cut.
    • Open ground control and load your file.
    • Set your work so the top surface is 3/4” from the waste board. It is critical if the sled will hit the bottom as it cuts the lower part of the part. If you are cutting a 1/4” board add a 1/2” waste board.
    • SECURE YOUR WORK. Not needed for a 4x8 sheet of wood but a 2x4 sheet can be moved by the sled causing chaos.
    • Understand where your origin is on your Gcode. Move the sled to that position and press define home. You will then see how your carving will look in the preview in ground control.
    • Make sure the z-axis is just touching the work. If not move it up or down to zero it and hit define zero.
    • Save and raise the z-axis for travel with the button in the z-axis menu.
    • Turn the router on
    • Click the play button and let her rip.

    Tips and Tricks

    • The depth per pass should not be > 50→100% of the bit diameter.
    • If the bit is shaking or the work squealing, slow it down a bit.
    • Configuration Variables (if it needs re-calibration)
      • Distance between motors: 3006.55mm
      • Distance from top of workspace to Motors: 804.5mm
      • Rotation radius: 165.5mm
      • Chain sag correction: 29.032674
