Progress on the 6502 computer – Milling PCB’s

While work and other commitments have been sapping a large amount of my time I have been making slow progress with the milling of circuit boards for the 6502 computer project. I have added some pictures of progress below. I am slowly getting the hang of repeatable and reliable results on the mill. Most trouble stems from the height at...

First milled PCB

After much tweaking, fiddling and procrastinating I have finally been able to successfully mill a PCB! The only minor issue I had was with the drill file created by the PCB-GCode script which would not load correctly into LinuxCNC. Luckily this is a step that I can complete manually using my PCB drill. The results are excellent, the finish is...

Milled PCB Test

A few pictures of a test run trying out isolation PCB routing. GCode was generated using the PCB-Gcode script for Eagle, using the backplane board from my 6502 project as input. Part way through the run I noticed that the mill was slightly out of alignment on the X-axis, this was causing shallow track cuts which got progressively worse the further...


Completed Mill

Some pictures of the finished mill and the first cuts of my own design. Prior to this I had done some test cuts using the default “LinuxCNC” logo, the very first cut was actually flipped on the Y-axis… Configuration fail!

Mill Build

Another one of those cool “toys” I thought I would never be able to afford but lusted after all the same. With the availability of cheap stepper motors, driver circuits and free software (LinuxCNC), CNC mills are starting to become quiet affordable for home use. Of course there are limitations. Just like my lathe this mill is only a baby,...
