  2. Copper wires 18 & 22 AWG for internal DC wiring based 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 based on the current and voltage
  4. Stepper motor cable connectors (optional) for more flexibility

Electronic System Consideration — Stepper & Servo Motors

Most modern automation machines, especially CNC, use stepper or servo systems. The most popular stepper motors are the 2-phase bipolar motor & 4-phase Unipolar motor. Servo motors may be DC or AC; brushed or brushless servo motors both require an encoder to control the motor shaft and provide feedback on the shaft position.

Mechanical Consideration — Weight & Force

Estimate the gantry or table weight for router, mill, plasma, laser, or lathe. Weight is not the only factor — also consider the force, which may be weight + resistance + gravity. In CNC machines, consider the cutting material & thickness to determine the force required by the XYZ axis.

Mechanical Consideration — Speed

Travel speed is when the machine moves from point to another without any resistance. Cutting speed is when the machine is engaged with the material. Cutting speed varies by material hardness and thickness.

CNC Operation Software / Motion Controller

CNC Operation Software controls the motion of a CNC machine — from 1 up to 6+ axis machines. CNC stands for Computer Numerical Control. Any machine with mechanical movement can become a CNC machine, and advanced CNC controllers can control 2 or more axes simultaneously.

MotionTek primarily uses Mach3 Controller, however our CNC products are standard and can be used with any step/dir controller available in the market. Mach3 is an open software which allows users to write their own VB Script code to control the CNC machine as needed.
