CRP4896 4' x 8' CNC Router Kit
CRP4896 4' x 8' CNC Router Kit
Our complete mechanical 4' x 8' machine kit offers the same high performance of our 4' x 4' machine with an even bigger work area at an incredible price point. There are hundreds of these machines currently running across a wide array of industries and applications all over the world. Order today from a trusted name in the DIY CNC business!

  • X travel 97.75 inches
  • Y (gantry) travel 50.25 inches
  • Z (vertical) travel 6.5 inches (minus spoil board thickness)
  • Dual drive rack and pinion for X
  • Rack and pinion drive for Y
  • 5 start ACME drive for Z
  • Repeatability to +/-0.002" or better, accuracy to +/-0.005" or better
  • Nema 23 version: Rapids up to 600 IPM+, cutting feedrates 200 IPM+*
  • Nema 34 version: Rapids up to 1000 IPM+, cutting feedrates 400 IPM+*

  • * Using CNC Router Parts electronics. Appropriate feedrates depend highly on material, depth of cut, cutting spindle and tooling.

What's included

  • The kit is broken down into the following subsystems:
    • Machine Base, 4' x 8' (CRP110-00-4896)
    • Machine Risers (CRP120-00)
    • Machine Gantry, 4' (CRP130-00-48)
    • Z-axis, 6.5" (CRP140-00-6_5)

    Kit includes:
    • Aluminum extrusion, counterbored and tapped for easy assembly
    • Pre-drilled cold rolled steel rails for X, Y and Z
    • Linear motion components (linear carriages, connecting plates and risers)
    • Drive components (screw, racks, rack and pinion drives, rack clamps)
    • All required fasteners


    The documentation is still in progress (see our 4' x 8' machine plans for the latest), but these kits include all of the parts needed to build the mechanical portion of a 4' x 8' machine. More detailed photos and drawings will be available in the future, but for now the documentation is comprised of the e-drawings plans and parts list on this website, and corresponding labelled boxes and baggies for subsystems and components.

    What's not included

    This kit contains all of the mechanical components needed for a CNC motion system, but there are still a few things needed to make a complete CNC cutting system. These are not included in this kit to allow people flexibility for different electronics, software, and cutting tools. If it's not listed above or in the plan Bill of Materials (BOM), it's safe to assume it's not included, but to be clear, these items will need to be purchased separately:
