Building a vacuum plate for PCB routing

One of the fun things I’ve been using my desktop CNC machine for is to make printed circuit boards using the isolation routing technique, where essentially you start with a copper clad board and remove material from it to isolate areas of copper to make pads, traces, etc. Once I had the initial setup done […]


CNC Control software

Having just looked at the physical CNC controller in the previous post, let’s have a quick look at some CNC control software. This software has the job of reading the CNC codes (“g-codes”), interpreting that data, and sending the appropriate signals to the CNC controller. The development of CNC control programs that run on a […]


CNC controllers

Having just looked at the physical CNC machine, we’ll next take a look at the unit that supplies all of the power and signals to the motors, switches, etc. The photos below show the front and back of the control unit for my little CNC machine. Larger CNC machines have controllers inside them, as well […]
