All of the buildings, all of those cars
were once just a dream
in somebody's head
Mercy Street - Peter Gabriel
A few years ago, Elektor Magazine had an interesting DAC project with high end aspirations based on the Burr-Brown (now Texas Instruments) 1794 DAC for a modest price.
I’m the lucky owner of a Devialet Expert Pro 250 (which started as the D Premier many moons ago) driving a pair of Martin Logan CLX Art. (Yes, it’s as good as the many raving reviews say. If you have to chance to buy one, don’t hesitate).
Another problem I encountered with my cheap CNC 3040 was the cheap spindle. First problem was that it started vibrating (a lot) at certain speeds. Another problem was the higher than expected run out (i.e. rotation inaccuracy which occurs when the tool is no longer aligned with the main axis).
Now that everything is working properly, armed with a fresh set of blank PCB’s and plenty of CNC mills it’s time to try out if machining a PCB is feasible.
After a lot of searching, and being totally new to CNC milling, I decided to go for a commercial solution and finally settled for this: Mk3/4 controller with enclosure and accessories
