CNC Build Part 5: Electronics #3DThursday #CNC

With most of the mechanical assembly complete.  It’s time to start wiring things up.

All the wires run to the back of corner of the cabinet where the electronics will be housed.  I modified a PVC outdoor outlet cover with cutouts and added a foam gasket for the wiring.  This will help keep the dust out.  The doors are also gasketed and the air intake vent is fitted with a dust filter.

The control computer is a recycled PC running XP and Mach-3.  I chose this older PC because it is ‘fast enough’ and has a native parallel port.

The motor controller modules are housed in a PC tower-case.  The ATX power supply provides power for the logic circuits and fans.  A separate 48v power supply provides power for the motors themselves.  ‘BOB’ the parallel port breakout board connects the motor controllers to the control computer via a parallel port.

Mach-3 control software is installed on the control computer.  The monitor is mounted on an arm near the front corner of the rails for good visibility.

Next 3D Thursday:  We’ll install the spindle and power it up!


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
