ASSEMBLY INSTRUCTIONS FOR THE MILLRIGHT CNC MEGA V FS
Be sure to check the resources page for the most updated assembly instructions.
The resources page has a parts picture guide to further assist you in assembly.
Important safety rules for operating your MillRight CNC Mega V FS:
Never place your hands near a spinning end mill or bit. Keep your hands off the gear rack!
Always wear eye and ear protection while operating your machine.
Always run a dust collector or wear a mask while performing a milling operation.
Do not leave the machine unattended while running a milling operation.
Do not operate your machine while under the influence of alcohol or drugs.
Secure long hair and loose clothing so it is not caught in spinning mechanisms.
Ensure work pieces are properly secured before running a milling operation.
Keep a fire extinguisher nearby.
Visually inspect wires prior to power up to prevent short circuits.
The Mega V FS is a big, heavy machine. Plan on spending a full weekend in assembly and seeking help with moving or
flipping heavy assemblies.
We recommend using a blue thread locker on any fastener not secured with a lock washer or lock nut.

Summary of Contents for MillRight MEGA V FS

  • Page 1 Keep a fire extinguisher nearby. Visually inspect wires prior to power up to prevent short circuits. The Mega V FS is a big, heavy machine. Plan on spending a full weekend in assembly and seeking help with moving or flipping heavy assemblies.
  • Page 2 V-Wheels Parts V-Wheel Kit • V Wheel Body (12) • 608 Bearing (24) Hardware V-Wheel Kit • M8 Washer (12) Tools Hard Surface Something Flat to Press Bearing Place the v-wheel body on a flat, hard surface. Place (1) 608 bearing on top of the v-wheel body.
  • Page 3 Place a second 608 bearing on top of the v-wheel. Press the bearing into the v-wheel using your impromptu tool. Pinch the inner races of both bearings with your fingers and test that the v-wheel spins freely. Repeat this process with the remaining v-wheel bodies. Set the v-wheels to the side.
  • Page 4 Locate the right gantry end plate. Place eccentric spacers (2) in the large holes on the top of the gantry end plate. The recessed pockets should be face up. Place a v-wheel on a M8x40 machine screw. Spinning the wheel on the screw will help to align the washer that is between the bearings.

  • Page 6 Locate the anti backlash nut (ABN). The ABN will come with (2) M5 nylock nuts, a M5 grub screw, and a M5 jam nut in the bag. Push the nylocks into the hexagonal holes on the face of the ABN with the nylon facing up. Screw the grub screw into the top of the ABN until it touches the bottom through the gap.
  • Page 7 Locate the router mount. Carefully turn the Z plate on its side making sure the bearings stay on the rails. Place (2) 5/16x3/4 button cap screws through the back of the plate using the 2 large holes at the bottom of the Z plate. Attach the router mount to the Z plate and tighten the router mount screws.
  • Page 8 Tools Phillips-Head Screwdriver Needle Nose Pliers 2.5mm Hex Key 8mm Socket or Wrench 10mm Socket or Wrench Locate your Z screw seat plate and UHMW screw seat. Place the UHMW screw seat on top of the screw seat plate. Make sure the pocket of the UHMW screw seat is facing up as shown.
