・Precautions
◆Intended Use
The intended use of the PCB Prototyping Machine is to process PCB by milling,
drilling and routing. Any other uses are strongly prohibited.
◆While Processing
Keep away from the machine especially the spindle head while processing.
Spindle head is constantly moving. Be sure to keep away and not to get your
caught in the machine. Make sure to wear eye protective gear/goggle while
processing.
◆Power Voltage
The allowable voltage for FP-21T is 85Ｖ～264Ｖ.If the voltage of your
region is out of range, be sure to use voltage regulator.
◆Working Area
The working area of FP-21T is 350mm x 250mm. Be sure to process within the
working area of Auto Lab.
◆Dry Run and Milling Speed
Below is the optimal speed for Auto Lab.
Dry Run ‥‥ 20～30mm/sec
Milling Speed ‥‥ 12～18mm/sec
Routing Speed ‥‥ 1～2mm/sec
If the processing speed is too fast during processing or manual operation,
step-out could occur to the machine.
◆Milling/Drill/Routing Tool Settings
The machine will process with the settings in CAM Pref.→Milling ･Drill ･
Routing. If the parameter in the setting is missing or unintended value, there
is a possibility of tools breaking or processing error occurring. Be sure
to check the parameter in the settings.
◆Vacuum Cleaner
While processing, if the dust from the PCB piles up, not only the processing
quality is affected by it, there also is a chance of spindle motor
malfunction. Be sure to use Vacuum Cleaner while processing.

2
◆CAD with Dongle Key
Make sure to remove Dongle key when you are using the prototyping machine.
Connection error may occur and prototyping machine may be unable to use.
◆Tools and RPM
For processing, set the RPM to 30～40. The unit in the software is x 1000RPM.
To drill 0.3～0.4mm size holes, set the Lower2 3～4mm/sec.
IMPORTANT
To drill 0.3～0.4mm size holes, go to CAM Pref. →Board Maker and set
the Lower2 3～4mm/sec. After setting the Lower2 speed slower, make sure
to set Drill Wait and Before Cutting longer than the default setting. If
not, there is a possibility of spindle head moving too early before the
drilling is completely penetrated.
◆Transportation
Since the Auto Lab precision machine, use the container box which was used
for shipping. For long distant transportation using carrier, make sure to
select carrier with great handle care with the transportation.
Do not apply any force to the shaft, lead screw, spindle head while
transportation. It could result to have the accuracy to drop.
◆Spindle Motor Cleaning
Note that spindle motor and collet are ultra-precision component. In order
to keep the machine performance well, daily checkup and cleaning is necessary.
Spindle motor may result to malfunction when dust or debris are caught between
tool and collet, decreasing the holding power of the tools. Make sure to check
and clean the spindle motor before using.
◆Warranty
The term of warranty for PCB Prototyping Machine is 1 year with the intended
use. Note that spindle motor and consumable supplies are not included in the
warranty. Also note that even within the warranty period, below circumstances
will be considered as charged repair. Improper use, inappropriate assembly,
damage/breakage by carelessness, natural disaster, abrasion, modification,
use of non-genuine components/parts, use in undesignated voltage. Please
operate with great care when you are using the machine without any training.

・Setup Operation Check
1．Connect the power cable to the AC In (Power Plug).
2．Attach and hold the vacuum hose by fixing the plastic vacuum holder on the
backside of the machine with the screw.
3．Attach vacuum hose into the connector.

4．Connect the USB cable to the USB port.
5．Connect the Vacuum Cleaner to the Prototyping Machine with power cable. Be
sure to turn the Vacuum Cleaner power “On”at all time.
6．Turn the power switch “On”. The spindle head will move to the back left
corner.
