Let’s all slow clap for [Daniel Taylor] who, after a long journey, got his home built PCB mill up and running with remarkable precision. That’s 10 mil traces with 0.5mm pitch pads. We’re impressed! The board will be used for breaking out the connections of an LCD screen he has on hand.
After seeing a CNC project as yesterday’s Fail of the Week it’s nice to look in on one like this that does some amazing stuff. In fact, [Daniel’s] creation has been working for months already. The link above is the project log he kept while hacking, tweaking, and retrofitting his rig to get the level of precision he was after.
Improvements include swapping out drawer slides for proper linear bearings and completely reworking the Z-axis along with a motor upgrade. For those that aren’t fans of the reading (how did you make it this far into this feature?) you can take a quick look at his image gallery which includes captions.
