Looks to me like you are well on the way to your first build.
The threads are steep but with a 'microstepping' controller and your 200 step motors you should be OK for all but precision stuff.

btw. None of us knows it all so you are amongst equals here.

And finally this one is for that Guy at work that we all know.

Not so sure that S** will be too pleased with his one though.

Have you noticed that just about everything these days seems to carry an obligatory Warning Notice.

(engraved and then profile cut with the same 1mm diameter endmill).

Now that's what I call innovation.

I recall using the wife's cheese board for a project a little while ago (http://www.machsupport.com/forum/index.php/topic,4314.0.html).

Excellent work.
I wish that my first machine looked as good as that.
How much does it cost please ?.

Thanks to Jeff and by following the links he has given - over the last two days I have learn't a great deal and now have a far better understanding about isolation routing. For those who participate in this process it is far far more than just making circuit boards, their varying techniques, differing cutters used and fineness of detail produced can almost be regarded as an art form in itself.

Because the cutter loadings are extremely small even the most basic and less rigid of the CNC machines have been shown to produce excellent and professional results.

Certainly the Eagle software together with JJ's ulp produces Mach ready routing and drilling files which would be extremely hard to better.

For anyone wishing to make a circuit board or explore a whole new side to CNC I can certainly recommend this method.

Hi Jeff,

The smallest hole I drill is 0.77mm but most often I use 0.96mm as this allows for everything. For cutting the tracks I used a 60 degree engraving bit (which is what I assumed everybody else used) but as I said earlier I have not done this before.

Best regards,  Tweakie.
