Last week, on our Instagram page, one of our community members asked what the recommended technique is for cleaning up PCBs after milling one on the precise Bantam Tools Desktop PCB Milling Machine. While we responded to the thread, we thought this information could be useful to more folks out there. If you've ever wondered that same question, this post is for you.
What if I told you that you could mill precise PCBs in a fraction of the time, increase trace precision, and essentially eliminate the experience of breaking bits? Starting with version 0.27, the Otherplan Public Beta makes this possible with a new feature: engraving bit isolation milling.
It’s easy to get confused when trying to tell the difference between our smallest end mills, so we made a visual guide! Looking at them side-by-side, you can see that there are subtle differences. For example, a 1/100" flat end mill looks very similar to a 1/64" flat end mill, but the tip is shorter and slightly smaller. That being said, even experts confuse them occasionally, so we recommend keeping your end mills organized. Many people keep them in their original packaging, but you can also mill your own bit rack!
