Nice Board;
What software are you using for the g-code?

Submit pictures of boards you've milled here for examination..haha.
I enjoy seeing what others have accomplished.
*no this board was not useable, just testing bits

Eagle and pcb-gcode.
I know more people have milled boards, so dont be shy post those pictures for everyone to see....and maybe ttell us what software and bits???
Ok, Ill jump in and post some pics.
I use eagle/pcb gcode and mastercam to generate boards.
I use 60 deg pcb milling bits that I make at DrewTronics
The machine is home made 10k rpm, ballscrews and servos.
These boards are approx 1 inch square surface mount adapters.

Those look great Andrew. I used 90deg bits on mine. I was going to try some 45 or 60deg bits to see if the traces can be milled finer. What do you use to hold your boards to the table? I have recently switched to the superglue method. It seems to hold the boards more evenly. A vacuum table would be slick....hmmmm
One more pic of a board I did a while ago......
Buckeye,
Well the superglue method looks like it is working quite well for you! All your boards look sweet.
I am using a vacuum table to make my boards and a small rotary vane pump from gast that works slick and is nice and quiet to run.
I ran a few boards with 90 deg bits, the cuts are so clean its amazing, but it is more difficult to achieve a fine pitch with them. The cut width gets wide fast the deeper you go into the board. I find the 60deg tools allow me to get the cut width down to .005 inch wide without difficulty.
I don't sell many 90deg tools but some folks do ask for them. I think most folks have a difficult time keeping the board flat enough to use 90 effectively.

Here's some of the work I have done (not that much): PCB Work | mcphill | Fotki.com, photo and video sharing made easy.
[QUOTE=mcphill your hole registration looks way off. Did you drill then mill, or mill then drill? What kind of drill bits are you using? I aleays use the engraving bit to spot my holes so the drill doesnt wander.
Nice boards...thanks for posting.
i enjoy looking at these. keep them coming.
That one hole was way off, which is why I took a picture. Turns out it was supposed to be that way ; )
I drill the holes from the top side before flipping to do the back (these are two sided boards) - the flip causes some of the misalignment.
It was fine for my needs, and I have only done a few. I have created a fixture to give me much better registration for the next time I do boards, but I have found a source that can make my boards professionally in a week or two, which is faster than I need them anyway...
