Safety
The spindle moves at a very high RPM and can hurt you if you contact it while it is moving. The
motion of the spindle can be difficult to detect and it does take a few seconds to spin down after
it has been commanded to stop. It is important to be extra cautious around the tool and spindle.
Always double check that the tool is not spinning before removing your part or approaching the
machine.
Maintenance
Air- Air must be attached to run the spindle, the software will not allow you to run the machine
without air hooked up and turned on to a certain pressure (0.2MPa or about 30 psi).
Warm-up- The spindle requires warming up after periods of disuse. On the user interface,
there is a “Warm-Up” button that will start the warm up program, this program should be run
anytime the machine has been cooled down or heated up (i.e. shipping in extreme temps). After
starting the warm up cycle the machine will run the spindle for about 50 minutes if it has been
off for more than 7 days. If the machine has been off for more than 12 hours, this program will
run for about 10 minutes. Do not interrupt the warm-up cycle and note that it will stop
automatically. If the Warm-Up runs longer than the 50 minutes or 10 minutes expected please
call support at Pocket NC, 1(406)451-3799.
The warm-up cycles the speed of the spindle, increasing the RPM every few minutes. The main
reason for the warm-up cycle is to evenly coat the bearings in the spindle with lubrication before
cutting. This is necessary in order to avoid damaging the spindle or the motor.
Cleaning- The spindle on the should be cleaned regularly. Cleaning the spindle with any sort
of liquid, except alcohol, is not recommended. A Q-tip with most of its fluff removed and a little
alcohol can be used to clean the inside of the spindle and collet. When cleaning the outside of
the spindle and the spindle housing it is best to have the air on  and then use a vacuum and dry
rag to remove any chips and dust that has accumulated.

Getting Started
When you first get your machine you will need to remove shipping bolts, install into the
enclosure, hook up an air supply, and install the tool.
Removing Shipping Bolts
Note, this step can be seen in video form here:
https://www.youtube.com/watch?v=2H1Mnk9O__w from 0:10 to 0:35
There are four shipping bolts installed in the Pocket NC in order to lock the axes in position and
prevent damage to the machine during shipment.
These bolts must be removed before the machine may be used. The bolts are M6x8x25
shoulder bolts. The 4 mm hex key is needed to remove them is included in the kit shipped with
the machine. The bolts are installed only hand-tight.
Do not discard the bolts. They should be retained with the rest of the machine packaging in
case the user needs to ship the machine in the future.
The locations of the 4 shipping bolts are shown in the images below. Two of the shipping bolts
are located behind the Y-axis. When the user is looking at the back of the machine they are
located in the lower-right quadrant of the machine.

The other two shipping bolts are located on the X-carriage behind the spindle. They are both
accessed from the top of the X-carriage.

Enclosure Installation
This section explains how to mount the machine into the enclosure. This can be a bit tedious,
but you only need to do it once as the machine will stay mounted inside the enclosure.
Materials Needed:
- (5) M4x6 screws*
- (5) rubber bumpers (optional)*
- Pocket NC V2 Enclosure
- Pocket NC V2 Mill
*Included in enclosure hardware kit
Tools Needed
- 3 mm hex driver or hex key
1) Remove the 5 feet from the machine (where the red arrows point to in the photo above
left).
2) Place the machine on the shelf inside the enclosure.
6

3) With the enclosure carefully overhanging a table or workbench as shown, start one of
the M4x6 fasteners into the screw hole closest to the USB port using a 3mm hex key.
4) Rotate the machine so the chip tray opening is hanging off the table and install one of
the M4x6 screws into the back of the machine.
7

5) Rotate the enclosure back to the first position and tighten the first screw.
6) Carefully place the enclosure on its back and fully open the lid to prevent it from opening
on its own.
7) Install the 3 remaining screws.
8) Clean off the bottom of the enclosure and stick on the 5 rubber bumpers if desired.
Note: This enclosure is not designed or intended for shipping with the PocketNC installed, make
sure to remove your machine before shipping!
If moving the enclosure be aware that the lid can pop open, secure it shut with tape if moving.

Connecting the Air Supply
Note, a video of connecting the air supply can be viewed here:
https://www.youtube.com/watch?v=2H1Mnk9O__w from 0:47 to 1:26
Below is an example of the air setup required to run the Pocket NC V2-50. Please note that the
source of air and inlet hose may differ. The user will need to supply and install the appropriate
adapter into the ¼” BSPT port on the inlet side of the filter in order to hook up the desired air
hose. Note the machine comes with the air regulator and filter (the tan colored piece of
equipment hanging on the pegboard in the photo below) as well as all black tubing. The
machine does not come with the red tubing or the air compressor shown on the left of the photo,
the user will need to supply input tubing and air supply.
9

In the setup above, the air supply is a Gast air compressor with ¼” air hose (red) supplying air to
the CKD filter and regulator that is included with the V2-50. The 4mm (black) hose supplies air
to the tee on the backside of the spindle, which supplies air to the internal air sensor. The tee
also carries the air to the spindle using a short length of 4mm hose connected to the blue
connection on the end of the spindle motor. It is important that air comes into the tee and then
out of the tee and into the spindle so that the machine recognizes that air has been provided.
The recommended air pressure for the V2-50 spindle is 25 psi or .17 MPa. This can be adjusted
using the knob on the bottom of the regulator by pulling down to unlock it and then turning to the
right for more pressure or the left for less. It is best to push the knob back up into its locked
position after adjustment to reduce the risk of accidental pressure adjustments.

Installing or Changing the Tool to Cut the Aligner
Corresponding video is here: https://www.youtube.com/watch?v=vq8tZN9lZa4 from 1:14 to 1:28
1) Make sure the spindle is off (it can be hard to tell when running at low RPM’s)
2) Locate the lever on the spindle and pull it towards you until it clicks into the “Open”
position.
3) Insert the tool into the collet with the desired amount of tool left sticking out
4) Push the lever back to the vertical (away from you), “Lock” position. Give the tool a bit of
a tug to make sure it is secure.
Turning on the Machine for the First Time
1. Plug the power cord into an outlet and then connect the other side to the machine (lower
right).
2. Plug the USB into a port on a laptop or computer, and then plug the other side into the
machine.
3. Turn the machine on (press the button above the outlet to the left, the - should be
depressed).
4. Wait 1-3 minutes for the red LED light to start blinking.
5. The first time you turn on the machine you will need to download the drivers for the
machine. Those can be downloaded here: https://beagleboard.org/getting-started#step3,
scroll down to this area and download the driver appropriate for the system you are
running. Then install the driver.
11

6. Once the driver is installed and the red LED is flashing open a browser (Chrome, Firefox
or Safari) and go to 192.168.7.2. Note, internet explorer browser will not work. Note you
are not connecting to the internet here you are connecting to the address of the
machine, so you do not need an internet connection.
7. The User Interface will open as shown below.
12

8. By default the power to the axes will be off, in order to enable the axes click on the
“E-Stop” button in the upper right corner of the screen. You will note that the E-stop (red
button) on the Pocket NC mill will blink until the motor power is enabled and will be solid
after the motors are active. The E-Stop button turns to red to indicate it’s on.
9. Before running any programs the machine must be homed. Click the “Home All” button
in order to send all axes to their home positions. The screenshot below shows the
coordinates of the machine’s home position.
13

10. Lastly, run the Warm-Up cycle, this will prepare the spindle to cut. If the machine has been
off for more than 12 hours but less than 1 week it will run a 10 minute warm-up cycles. If the
machine has been off for more than 1 week it will run a 50 minute warm-up cycle. Before
running the cycle be sure that the tool is installed and secure (it is not good to run the machine
without a tool installed in the spindle) and that the air is on. Do not interrupt the warm-up cycle
and note that the warm-up cycle will stop automatically.
Measuring Tool Offset (telling the machine where the end of the tool is)
Corresponding video https://www.youtube.com/watch?v=vq8tZN9lZa4 1:55 to 2:50
1) Make sure the machine has been homed (Home All).
2) Navigate to the “Tooling” page of the user interface which can be found in the upper left
between Production and Conf.
14

3) You will then see the tool table, as shown below. With the tool installed click the
“Measure Tool 1” button in the right most column.
15

The following prompt will appear in the bottom right corner of the screen, click the green flashing
LED on the machine.
The resulting tool length offset should measure between -3.0 and -3.5 to properly cut out an
aligner. If this value is not achieved change the length of the tool and re-measure.
Shutdown of the Machine
●When you are done operating the machine, click on the power button symbol in the
upper right corner of the screen this shuts down the machine, but also safely shuts
down the Beaglebone Board. A pop-up asks you if you would like to completely shut
down the V2 machine.
●Shut off the power button on the Pocket NC and unplug the machine from the
computer.
●The computer may generate an error message warning you to eject the BeagleBone
before unplugging it. You may eject the BeagleBone from the computer if desired,
but it is not necessary.
●Turn off the machine, unplug the USB and the power cord when not in use.
