General Description
This CNC Machine is designed for high performance and precise maneuvering in three dimensions.
The CNC Machine is capable of the following applications: milling, drilling, soldering, paste dispensing,
and air brushing. The rigidity and technical characteristics allow full use of multiple tool heads for light
duty milling, paste dispensing, and silk screening.
The pendent controller allows the operator to move each axis to the initial starting position of the
desired operation. The multiple methods of communication allows the operator to carry out operation
tasks by loading files to the machine by while the machine is powered on by means of either a U.S.B,
Serial, and Ethernet as well as offline means of a flash drive. The part can be machined automatically
once the file is implemented. The program can be implemented again for future use, without machine
down time being required. This makes it possible to machine parts more precisely and efficiently than
with conventional mills, air brushes, soldering and paste dispensers.
Basic Setup of the Machine:
The CNC machine is comprised of the following assemblies and components.
Base assembly: Shown in Figure 3-1.
Y Axis assembly: Shown in Figure 3-3.
X Axis assembly: Shown in Figure 3-4.
Z Axis assembly: Shown in Figure 3-5.
Motor mount assembly;
Hand Held Pendent;
Control Panel Box;
Lubrication system of each axis;
Machine configuration ready to install paste dispenser (bolts into Z Axis Assembly);
Installation-Mechanical
The CNC mechanical assembly shown in Figure 3-1 is composed of the Base Assembly, Y Axis
Assembly, and Z Axis Assembly. These assemblies are shown in Figures 3-2, 3-3, 3-4, and 3-5
respectively. These figures show the individual components and their mounting locations.

Power Requirements
The CNC Electrical Cabinet requires 120 VAC and 12 VDC from the AC adapter provided.
Installation Requirements- Electrical
The CNC machine has been shipped assembled and installation only requires connecting the
machine electronics and attaching the desired tool head. The electronic connections that are required
include: the motor wiring, the power cables, and the tool head cable. The tool head is mounted to the
z-axis using the supplied 3/8-24x1in bolts.
Connecting the Motor
The CNC comes with 3 sureStep motors wich are 4 lead biploar motors. The cables for each
motor come with quick connect adapters that are connected to the Electrial Unit.. See Fig__ for
motor connector location. Internal connections from the quick connects to the Motor Driver
Board come pre-connected
Internal Motor connection to Motor Driver Board
The quick connect cables connect to 3 inpendent therminal blocks labeled X-axis, Y-axis, Z-axis.
Each terminal block has 4 wire connections labeled A+, A-, B+, B. See the digram below to
connect the Motor leads to the terminal block

Connecting the Motor Power Supply
The power supply comes fully connected internal to the Electrical Unit. There are 4 power
supply connections and are located in the upper right corner of the Motor Driver Board. The AC
input is label AC1 and AC2. The DC power is label Vm+ and Vm-. See Fig__ for location of
AC and DC input power.
Note: Make sure that the wires Vm+ and Vm- are connected to the correct Thermal Block
connectors. A reversal of polarity will destroy the board.
Connecting the Motor Driver Board Power Supply
The power supply comes fully connected internal to the Electrical Unit. Your CNC Motor Driver
Board is setup for 120 VAC. It can also be used be used with 240 VAC. See table 4 for
configuration settings.

Pre-Operational Checklist
Insure that the linear guide rails are cleaned and oiled before the first operation.
Grease the thrust bearings and the linear guide blocks.
Tighten the belts to the proper tension.
Insure that the tool head bolts are secured, as well as connecting bolts that provide rigidity to
the machine.
Make sure that all wiring connections are not loose or exposed.
Operational Checkout
Connect 12 Volt DC.
Connect AC power cable.
Turn on Front Panel Power switch.
Verify green LED on motor driverboard lights after 15 seconds.
Verify green LED on main controller board is lit.
Note: If either greed LED is not lit see troubleshooting section.
OPERATION
3-1 Power Supply Indicators: There is a 5V indicator light lit during normal operation. Insure that is LED
is lit by looking through the top of the electronics housing box.
Hand Pendent Controls and Indicators
See user’s manual for Hand Pendent Controls and Indicators
Troubleshooting
Mechanical Alignment
If the alignment of the machine during operation appears to not correspond to position values being
sent from the controller, there is a problem with the axis.
Localizing Trouble to the Circuit
Main Controller Board
If main controller board LED is not lit, there is a fault in the system.
Verify fuse blown indicators are not lit.
If fuse blown indicator is lit. Replace Fuse and Retest.
If fuses blown indicator is are not lit replace controller board.
Motor Driver Board
If Motor driver board LED is not lit, there is a fault in the system.
Verify fuse blown indicators are not lit.
If fuse blown indicator is lit. Replace Fuse and Retest.
If fuses blown indicator is are not lit, replace motor driver board.
Preventative Maintenance
There is no preventative maintenance required for the machine electronics. However, several
components on the mechanical system require lubrication. These components include the linear guide
rails and ballscrew which require oiling and the thrust bearing blocks and the versa rail blocks require
routine greasing. Also, the table top should be removed periodically to remove the metal shavings and
other debris that has collected during milling and machining operations. Also

Alignment and Adjustment Procedure
Adjustment of Motor Phase Current
The motor phase current is set by adjusting resistors VR1-VR6 for the voltage level
calculated from the above formula (1) or Table 3. VR3, VR4, VR6 are the coarse adjustment
resistors. VR1, VR2, VR5 are the fine adjustment resistors. See Fig.__ for location of test
points and adjustment resistors.
Figure 8-1: Adjustment of Motor Phase Current
The following steps are used to set
for each axis.
1. Calculate
for each axis using the above formula.
2. Turn on the power
3. Connect a voltmeter (set for
) between TP1 (X) and GND and adjust VR1
and VR3 for the desired voltage (
).
3. Repeat step 2 for TP2 (Y) using VR2 and VR4.
4. Repeat step 2 for TP3 (Z) using VR5 and VR6.
5. Turn off the power

The Motor Driver provides a Low Voltage Power Supply which generates four voltages levels 5,
+12, -12, and 24 Vdc. The 5Vdc Supply provides the power to the Optical Isolation and Microstepping Sequencer. Step, Direction, Enable, Reset, MS1, and MS2 are all Optical Isolated
inputs from the Main Controller. The Step input signal steps the motor. The Direction input
changes the direction of the motor. The MS1 and MS2 inputs set the micro-stepping mode
which is either full, half, ¼ or 1/16 step mode. The Voltage Reference (Vref) determines the
maximum current through the motors and there are 3 independent Voltage References for each
axis. The Motor Power Supply provides the power to the motors. The Micro-stepping
Sequencer controls the Mosfet H-Bridge which drives the motors. The Motor Driver Board
provides three fuse blown LED Indicators and a 5V indicator which is lit during normal
operation. The Driver Board Ready, Vbb Ready, and Fault signal are outputs to the Main
Controller and provide status information of the Motor Driver Board.

SAFETY SUMMARY
The following are general safety precautions that are not related to any specific procedure and do not
appear elsewhere in this publication. These are recommended precautions that all personal must
understand and apply in the operation and maintenance of any equipment.
KEEP AWAY FROM LIVE CIRCUITS
Operating Personnel must at all time observe all safety regulations. Do not replace components or do
do any adjustments while power is turned on unless otherwise stated. Under Certain conditions ,
dangerous voltage potentials may exist when power is turned off due to charges retained by capacitors.
Always remove power and discharge and ground a circuit before touching it.
DO NOT SERVICE OR ADJUST ALONE
Under no circumstances should any person reach into or enter any enclosure for the purpose of serving
or adjustment except in the presence of a person cable of rendering first aid.
RESUSCITATION
Personnel working with or near high voltages should be cable of rendering first aid. Such information
can be found >>>>.
WARNINGS
DC Voltages of up to 50 Volts are present in the Electrical Equipment Chasis. Extreme
caution should be used.
