What do I need more to build my CNC Controller
|
|
Electronic Parts & Software |
1- Electronic enclosure ABS, Aluminum or Metal
structure as you prefer
2- Copper wires 18 & 22 AWG for internal DC
wiring base on the current and voltage
being held in that connection
3- Copper cable 4 or 8 Wires 18 AWG rated
300V shielded Stepper motor cable
base on the current and voltage being held in that
connection
4- You might add stepper motor cable connectors for
more flexibility
5-
Mach3/4 CNC Router, Plasma and
Mill controller
6- Instructions and wiring diagram provided with
each CNC KIT |

Electronic system Consideration
|
|
1-
Stepper & Servo motors
Most modern automation machines specially CNC uses
stepper or servo system
both Stepper & Servo motor have many types.
Stepper motor
is basically a synchronized brushless DC motor, the most
popular stepper
motors are the 2 phase bipolar motor & 4 phase Unipolar
motor, 3 & 5 phases are less used
in the CNC industry.
Servo motors might be a DC or AC motors, Servo motor
brushed or brushless both require
encoder to control the motor shaft and provide feedback
on the shaft position.

Mechanical Consideration
|
When you select parts to build a CNC Mill, Router
Plasma, Lathe or Laser machine you
should consider many mechanical issues
1-
Weight & Force
Like estimating gantry or table weight for router, mill,
plasma, laser, lathe
The weight is
not the only factor you should consider the force which
might be the
weight + resistance + gravity, force might have many
formulas depending on applications.
In CNC machines consider the cutting material & thickness to
determine the force required by XYZ axis.
2- Speed
Travel speed is when machine travelling from point to
another without any resistance
caused by physical touch like when spindle engaging/cutting
specific materials
In case of CNC Mill or Router, Cutting speed is when the
machine engaged with the material
caused by physical touch between the router/spindle and
material.
The cutting speed varies from material to another depending
on the material hardness/thickness. |

CNC
Operation Software
/ Motion controller |
CNC Operation Software or CNC
Motion Controller are the softwares that control the motion
of a CNC machine, it might be 1 up to 6 axis machine or
sometimes more.
CNC stands for Computer Numerical Control like CNC Mill, CNC
Router CNC Plasma/Oxyfuel,
CNC boring Machine, CNC Plasma, CNC Lathe, CNC Embroidery
machine etc.
Any machine with mechanical movement can become CNC machine
and advanced CNC controller
can control 2 or more axis at a time.
Motiontek basically use Mach3 Controller however our CNC
product are standard as they can be
used with any step/dir controller available in the market,
Mach3 is an open software which allow users
to write their own VB Script code to control CNC machine the
way they need it.
Below some examples of Motiontek
interface built under Mach3
4 Axis control
with rotary, Spindle on/off speed control, cooling control
3 Axis
control with XY Axis Edge Finder, XY Axis Center Finder,
Z Axis Auto Zero
