Hi I got a full set of manuals for an 850SX Acramatic controller, from a cincinatti sabre 750.

They're big and dirty (the manuals) I'll have a look thru if you think it might be the same ?

Hey - thanks for that - very interesting reading. Cool project !

No thats not what I'm looking for tho... It is not a high precision machine.

As far as I know the professional machines mostly...

yeah, cheers, I have that one already...

Its still not what I'm after tho - as you said, its mostly electronics. I'm more having difficulty with the mechanics part.

I note that there is a...

Hi

Can't seem to find books that go into detail about how a modern cnc machine is constructed ?

Particularly with respect to geometry, discussions of pros and cons of various layout choices,...

Pardon me,

Are you looking for actual programming code algorithms, or simply a cam package that does what you're asking ?

I have some crude algorithms in Java for doing parallel lace on a...

Hello.

I am seeking to coat the underside of the pcb circuitry I have milled with something to increase isolation.

Ideally, I want something like that green stuff that is on commercial boards ?...

Thanks for the replies.

Much appreciated.

Thanks guys.

I think I get it now.

I thought the holes needed to be blocked, but just didn't know how.

Cheers !

Hello.

I am curious as to how a vacuum chuck holds down the workpiece efficiently if the workpiece is not big enough to cover all the holes that the vacuum is applied to ?

Can someone please...

Okay, so,

The milling procedure works great, the drilling procedure works great, the board is thankfully held flat and sturdy by some double sided sticky tape, everything goes well and wow-wee - a...

Hey uhm, BobWarfield:

Stop me if I'm wrong, but isn't that Ducatti part a photorendered cad model ?

Pardon me if you meant it as a joke - I suck at detecting sarcasm

Hey ahoodlum.

I had to mill some traces for a SOP chip that were 0.5mm lead spacing, and 0.5mm lead width (don't know what that is in mils, sorry !).

I got this conical tipped diamond coated...

Geoff -

That was exactly my issue - is there any way to reproduce the machine bed to the same tolerance as the reference without any further tools, like Rustybolts laser level ?

Or is a...

Hello again.

Thanks to everyone who contributed to answering an earlier question of mine.

I am very curious to know how to build machines from first principles. That is the root / basis of my...

Thank you all for your replies.

As a first time poster, I was pleasantly surprised at the speed and information content of the posts.

The useful information I have gained is:

- mass...

Greetings.

I am looking for ideas as to why machines are so commonly made with the worktable moving in x,y, instead of it being stationary and the spindle moving in x,y,z.

Downsides I see to...
