<p dir="ltr">That one did take quite a few hours it's an automotive ecu design that I wanted proof the machine could make before I bought it. So chris milled it out ir me on both sides. </p>
<p dir="ltr">NASA and Nokia both bought the same or similar machines for internal stuff too .</p>
<p dir="ltr">Fr4 is hard on bits but the bits just aren't that expensive. As for cleaning up it has a vacuum attachment that switches on and off automatically as it's cutting so it's perfectly clean after irs done.</p>
<p dir="ltr">On some boards I've dipped them for 30 seconds or so just to clean up any loose copper</p>
<p dir="ltr">I use seeedstudio. Itead. Advanced circuits and silver circuits for runs but having the mill is really useful . Plus it does cut other things and is fast spindle and quite accurate </p>
<p dir="ltr">In the years I've had it all I've done is occasionally change the 5cm rubber belt on the spindle drive and it comes with three of them .</p>
<p dir="ltr">Technology has come a long way and costs have decreased a lot. Especially bits. </p>

<div dir="ltr">It has a camera for fidicuals. You cut one side. Drill and align by two droll holes it marks out</div>
<div dir="ltr">I can do 4 mil repeatable and everything I do is smd. I use the lpkf rivets for vias and we picked up an electro plater off ebay for a few k</div>
<div dir="ltr">I've made 100s of prototypes at home on it over the years it's been great. </div>
<div dir="ltr">The bits I pick up from precise bits and there's Andrews bits on ebay you can get them for less than 10$ drill bit city has lots of drills for cheap</div>
<div dir="ltr">I have only broken a couple of bits on it. Usually router bits while cutting because I hadn't setup the software correctly and had never noticed <br>

<div dir="ltr">Chris over at accurate cnc has been great resource .</div>
<div dir="ltr">People often pop over at the weekend to my place to make something and it's a great teaching resource where people can go from learning to making a board<br></div>

I don't know its capabilities, but I do recall that drill bits break, and alignment is done by drilling guide holes before the PCB is fabricated - so that the drilling can line up with the traces. I also don't recall how long it takes to complete a board.<br>
<br>
I believe it's a lot of work to master the many steps required to finish a board this way. I suppose it can be faster than ordering a board from an outside shop, but you'll be spending a lot of time that you could use more productively on something else.<br>
