Portable CNC Router Controller

Setting up the right connections for a CNC router is certainly not the most complex task to do, but it takes some time. So we created a portable box, which provides supply as well as instructions to drive the router.

  • reduce the time for wiring, plus everything labeled so no more looking into connections.
  • can operate multiple routers having similar specification.
  • can be carried remotely.

The CNC router we are using: 500 mm X-Curve

 ***    This is just a brief summary and not a detailed specification    ***

Components present:

  • Power supply units
  • PWM board with potentiometer controller
  • Arduino board with Motor controller(GRBL Shield)
  • Supply system for LED, fan, continuity tester attached with CNC

 

Power Supply:

There are two power supply included inside the box, both 400 Watts,

  • 24V,17A
  • 48V,8.3A

The first one is for driving the motor driver(GRBL Shield), as well as the 4 Stepper motor of CNC and the other is for supplying power to the spindle.

PWM board:

The Spindle is supplied 48 volts passing through a PWM board, which helps to set its speed at desired level while working(0-65000 RPM)

Arduino board with the controller:

The Arduino board is running on GRBL shield(an open source solution to regulate the work of motor driver as per instructed), on top of it a controller board is mounted which comprises of 4 motor drivers for 4 motors(X, Y, Y’, Z)

Power Supply for additional units:

A connection from 24V PSU is fed to a transistor, which caps down the voltage to 12V, so that small units like a fan, LED can work.

  • 30000 RPM fan to remove dust from work bed.
  • LED for supplying light to work bed.
  • Continuity tester, to determine whether the cutting tool is in contact with the job, and also for probing purposes.
