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.

Get one section of long gear rack. Place M5x20 Button cap screw through
the holes (12) of the gear rack keeping the screws uniform. Spin a large t
nut a few turns on each screw. Leave the t nuts loose. Repeat process for
the remaining long gear rack and the short gear rack.
Slide the t nuts into the top of the Mega V extrusion with the gear rack
teeth pointing out from the extrusion, away from the v groove. Leave the
rack loose. The (2) 2650 Mega V extrusions will get the long rack. The 1465
Mega V Extrusion w/logo will get the short rack.
Designate one 2650 Mega V Extrusion as the right extrusion. Lay the
extrusion on it’s side with the rack teeth facing up. Locate a drag chain
mount. Place (3) drop-in t nuts in the groove on the opposite side of the
extrusion from the gear rack, near the left end of the extrusion. Put M5
split lock washers on (3) M5x12 button cap screws. Position the drag chain
mount with the slot facing to the left and attach the mount to the extrusion
using the M5x12 Button caps with lock washers and the drop in t nuts.
Locate the 1465 Mega V Extrusion with the logo. Lay the extrusion on it’s
side with the logo down and the rack teeth pointing up. Locate (2) drag
chain mounts. Place (6) drop-in t nuts in the groove on the opposite side of
the extrusion from the gear rack, near the right end of the extrusion. Put
M5 split lock washers on (6) M5x12 button cap screws. Position the drag
chain mounts with the slot facing to the right and attach the mounts to the
extrusion using the M5x12 Button caps with lock washers and the drop in t

Locate the (2) Y mid-span supports. In the middle of the 2650 Mega V
extrusion (1325mm), opposite the rack, place (2) drop-in t nuts in each
extrusion. Place M5 split lock washers on (4) M5x25 button cap screws.
Attach the Y mid-span supports to the 2650 extrusion using the M5x25
button caps with split lock washers and the drop-in t nuts. Orientation of
the Y mid-span support does not matter.
Retrieve the X/Z assembly. The mount is the bottom of the assembly, and
the motor is the top. The v-wheels will pinch the outside of the Mega V
extrusion using the v shaped slots on the top and bottom. If the v-wheels
are too tight to slide on the extrusion, use a 13mm wrench to turn the
eccentrics until the assembly slides onto the extrusion. Slide the X/Z
assembly onto the same side of the 1465 extrusion as the logo. Set the
2650 extrusion to the side being careful not to bend the drag chain mount.
Retrieve the left end plate. On the left side of the extrusion, use (4) 5/16 x
3/4 button cap screws to attach the left end plate to the extrusion. Repeat
the process on the right side with the right end plate. The end plates should
extend more from the front of the extrusion than the back. Set the 1460
Gantry to the side being carful not to bend the drag chain mounts.

sure the set screw is not sticking out the back (outside v) of the corner
joiner or they will not slide down the extrusion slots.
lat surface or table, lay out the (2) 2650 6060 extrusion with space for the
1465 extrusion between them. Take (1) 1465 extrusion and place (2) inside
corner joiners on each side of the extrusion (4 total for each 1465
extrusion). Make sure all corner joiners are on the same face of the
extrusion. The corner joiners will slide down the slot with one end in the
extrusion and stop at the edge of the extrusion with the other end. Make
sure the corner joiners stop at the edge of the 1465 extrusion. If they slide
down the slot, the orientation is wrong.
Page 16 of 33
Slide the 1465 extrusion into the 2650 extrusion. Repeat the process with
(5) of the remaining (6) 1465 extrusion. Keep the corner joiners pointing
the same way, towards the opposite end of the 2650 extrusion. The spacing
of the extrusion is about 371.66mm (14 5/8”) between the extrusions. The
last extrusion should be inserted into the other end of the 2650 extrusion
with the corner joiners pointing towards the opposite end.
Make sure the frame is square. Make sure the 1465 extrusion is flush with
the top of the 2650 extrusion. In the case of the front and rear 1465
extrusion, make sure the outside is flush with the ends of the 2650
extrusion. Tighten the set screws for the inside corner joiners.
The gussets will connect the 1465 extrusion to the 2650 extrusion on the
side opposite of the inside corner joiners. Place (2) drop-in t nuts, one in
each slot, on each end of the 1465 extrusions for a total of 4 drop-ins for
each extrusion. The front and back extrusions will have the gussets on the
same side as the inside corner joiners. Place (2) corresponding drop-in t
nuts in the 2650 extrusion for each set in the 1465 extrusion.
Using the M5x8 Button cap screws, attach the gussets to the 1465 Extrusion
and the 2650 extrusion. There will be (2) gussets for each 1465 extrusion,

Pick up one end of the frame and block it up. If on a table, hang one end of
the frame (2650 extrusion) off the table. Locate a Y end plate. Using (4)
5/16x3/4 screws, attach the Y end plate to the end of the 2650 extrusion
using the 4 holes close to the smaller M5 holes. The smaller holes should
be pointed up. Repeat the process for the other 2650 extrusion. The Y end
plates will act as feet. Place something underneath to keep from scratching
the end plates. Block up the other end of the frame and repeat the process
for the other side. Check square throughout the process.
Slide (2) 760 leg extrusions onto the inside corner joiners, one leg extrusion
for each 2650. There are two tapped holes diagonally from each other on
one end of the 760 extrusions. Make sure the tapped holes on the 760
extrusions are pointing up. Leave the legs loose. The legs will need to be
adjusted when installing the subframe. Leave the legs near the center of
the 2650 extrusion.
Place (2) M5x16 button cap screws through
the outside of the y end plate and lightly
thread on a large t nut to each screw. Slide
a 760 leg extrusion onto the t nuts. Tighten
the M5x12 button caps while making sure
the leg is flush with the outside of the 2650
extrusion. Repeat for the other y end
plates and legs.
Place (2) drop-in t nuts in the grooves of the
legs, one in each slot, for each face of the
leg that is perpendicular to the 2650
extrusion and the front/rear 1450
extrusion. There will be (4) drop-in t nuts
for each leg total. Use M5x8 button caps to
install gussets on the legs using the drop-in
t nuts. There will be 2 gussets for each leg.
The 2650 Extrusion and the front/rear 1465 extrusion will need (2) corresponding t nuts for each set on the
legs.
Do not connect the middle legs to the 1465 extrusion. The middle legs will only be attached by gusset to the
2650 extrusion. Leave the gussets loose as the legs will need to be adjusted when installing the subframe.
