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 ***
The controller:
Connections:
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.
