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.
    • The Gcode can be made by a variety of CAM programs. Some choices are:
      • Easel (Yes, you can use X-carve G-code on the Maslow)
      • KiriMoto (can be used within OnShape)
      • Fusion 360
      • Solidworks (On the Fox.Build CAD Machine)
      • Carbide Create (
      • MakerCAM
    • Be aware that the Maslow is limited in speed, so your feeds and speeds choices might be overridden.
    • 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 Webcontrol and load your file. (To open Webcontrol open a browser and go to localhost:5000).
    • Set your work so the top surface is 3/4” from the waste board. This is critical to avoid the sled hitting the support board 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 define home (click the Webcontrol button with a floppy disk and house). You will then see how your carving will look in the preview in Webcontrol.
    • Make sure the z-axis is just touching the work. If not move it up or down to zero it and hit define zero. This is in the Z-axis popup and has an icon that looks like a floppy disk.
    • 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'er 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
    • You can install Webcontrol on your PC to see how your design looks. However, you will only be able to run the Maslow from the PC in the woodshop. If you want to install Webcontrol you can find it here: Release First Release from New Repository · WebControlCNC/WebControl · GitHub
