For the basics this is true. But I plate thru-holes and tin the copper so I do use chemicals and wet processes.

When plating thru-holes, it is easiest to drill, plate then mill. It s difficult...

Are you asking about CNC Drilling a board or CNC Milling a board?

I small CNC mill is great for drilling. I made a video about it.

CNC for milling depends on the tolerances. Simple circuit...

I'm giving it a try

Interesting read, its been a while since I've been here.

I have two questions.

1. Does it handle z-axis changes in the middle of a long run? For example, a trace goes from x1.000 to x5.000...

I don't know if it would help you or not.

But when I mill lexon or acrylic I spray the board with wd40.
It helps a lot.

I've purchased two from him. I liked mine so much I got a backup in case he stopped selling them.

I've had an email go unanswered then wrote again to have him repond. I think they sometimes get...

Zig,
I'd be happy to buy you a beer anytime.

But Swither was the guy with the LPKF issues. :)

So there's no chance of fixing the control board?

Why not just get into copper plating your through holes?
It really isn't that hard. Here is my DIY process.

Personally I'd probably redraw it.

How big/complex is it?

Off topic now sorry.
The tool change macro parks the spindle at zero on all three axis, I release the spindle and slide it up in the spindle mount, change the bit and slide it back down until the...

If you're using the recent pcb g-code. It goes to the tool change z axis, before the tool change xy axis. That why it dragged over the board. You need to edit the code, find the place where it...

Looks to me like its just too many ipm.
How fast are you traveling?
It looks like is just plowing through the copper.

Thanks for the reply.
I don't intend to use Target, but I haven't looked deeply into it yet. Maybe this weekend.

My main problem is getting the cut depth to be consistent within 0.001" across...

Same here.
Vacuum table, drill from both sides.
It seems easier on the drill bits and doesn't mar the table.

The larger bits, above 0.935 or so, would need to drill past the other side pretty...

I use a low power microscope and have seen what you're talking about.

You can get small chips that short out the traces.

Try scrubing the board with some lightly abrasive cleanser.
Don't be...

Gareth,
Can you provide some details on which/where your found the extrusion and which collet chuck you are are using?

Did you actually get this to milling yet?

Neatman,
Thanks.
In fact, that what got be started on this whole thread.
I really appreciate your input.

Wow, this thread is really helping me out.
Thanks for all the input and responses.

Wow, you guys are moving right along on this. I thought it was a psdphk's original code.

I use Mach3 also, so I'm going to follow dhookings methods.

I'm confused on how to run the vb script...

Jay,
you ever try this?

http://phk.freebsd.dk/CncPcb/calibrate.html

I simply don't have access to such tools to build one.

I may try a chinese spindle some day.

Jay, I spent Saturday tricking out my mill some.

I replaced the vacuum table with a new one and added a camera with Macro Lens and a new dust collection method. There are two large vacuum pumps...

I will soon. Maybe another week or so.

Currently I'm completing some through hole plating videos.
I'll do the milling next.

PS: I asked about the runout because I'm always seeking the...

Ok, in reality, how about less than 0.001" runout. Or around 0.001".
And 20,000-30,000 RPM, And electric, not pneumatic.
And about $500.

So we have commercial rotary tools and routers.
The...

I'd like something High Tech. In the $500 range.
With zero runout and varible up to 30,000 rpms or so.
And a 1/8" collet.

That would be cool.

Have you ever measured the runout on that Bosch Colt?

Chuck

What are the options?

Seems most people use Dremel's or other rotary tools.
Of couse there is the Wolfgang Spindle.

But, has anyone seen anything else worth looking at?

I do the same thing, with 4 pins.

mholod,

Why do you post the same thread in every discussion about the Wolfgang Spindle? We've all seen it. It comes up in every search on the Wolfgang spindle. Richard offered you a full...
