Every serious audiophile knows that properly grounding his equipment is of
utmost importance to obtain the best possible sound quality. Of course
companies have realised this and offer their
own, very expensive, solutions. However, it can be a lot simpler, better
and above all, a lot cheaper.
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
Once I decided to pick up my electronics hobby again (around 2017) I had to think on how
to make printed circuit boards (PCB). Breadboards are nice for experimenting but at a
certain time it would be nice to have something more permanent on a PCB to build in a
nice case.
