Hey Anton and Tony,
Here is a thread that I wish I had found sooner.
http://www.machsupport.com/forum/index.php/topic,2968.0.html
There is some good stuff in there as well.
See Ya,
RC

Yes I'd found that one. The profiles Art posted work fine, but I'm having trouble with the inner one if I modify it. I've been playing with it most of the morning and managed to get several 'unrecoverable errors' which is always great fun.


Tony

Hey Tony,
I was tinkering with it too.
Not on the machine....just the PC.
Are you actually cutting a inner profile on your machine ? 
On the INNER example, it looks like one of the RAPIDS runs diagonally through the stock.
That would produce a horrendous wreck, wouldn't it ?
I suppose that would be edited manually in the posted code. ? ? ?
It looks like it's sort of doesn't realize that it's in the bore and has to z+ out before an X move. But I can't post code..no lic. yet and I'm not buying it until there is some evidence that it works.
I still wish they would free it up, either for a trial time perion or a line # limit like most others do.
Thanks Tony,
RC

Oh I've bought it, so that I could find out what the code does. It's cheap enough. As you say some of the paths can be rather dangerous so I haven't actually run any code live yet.
I haven't managed to create a new inside profile that works yet - even Art's example doesn't work if you change say, the right hand arc to a bevel.

I thought it was worth a gamble in case it really does become useful sometime.

Tony

GEEESH, I give up for now.
A simple profile, with the line drawn "Down to Centerline" to cut INSIDE.....1 chain...... flips to OUTSIDE when converted.
I don't get it.
I'm not the GAMBLER that you are Tony. However....I'd feel guilty if I didn't offer you at least a portion of what you've paid.
Thanks,
RC
BTW, ever heard of Code Shark ?

I haven't used Code Shark - its more of a G code generator & editor as far as I can see. The wizards in Mach will do a lot of coding for simple profiles & threading & it's easy enough to string a few operations together.
 I'm quite happy (but a bit impatient) to invest in what may turn out to be capable of doing more complicated profiles. Fortunately I'm not relying on cnc to make a living. Any machining work that I take on is usually prototypes in very small batches and better tackled on the manual machines.

Hi, RC

Been tied up hear a couple day's

I've looked at it some, You need to make 2 sep. DXF files, 1 outer, 1 inner.

Made a Master dxf, Then an Outer & Inner dxf, See below.

The outer post's, But the first cut is too big, The inner doesn't post, I can get a profile though.

Load ether Inner or Outer, Clean, Optimize, Move the marker from bottom left to bottom right, then use the post at top,

I think it will give you the profile Without the Pro License, Should be close I hope.

LazyCam Turn still needs Work, Who nows when that will happen.

Thanks, Chip

HEY Chip, Great to hear from you.
I understand what you've got there. Sort of what I expected but was not sure.

Tony, Chip, and All.

I made a very interesting discovery. I think. 

When drawing a profile to be cut on the OUTSIDE, the horizontal line to the left can terminate without turning up or down. LCam just uses the end of that line and the extended line on the right that is added to the profile. Clean/Convert does the rest. (first pic)

To cut the INSIDE, the line at the LEFT of the profile needs to turn vertically and be drawn BEYOND the added line on the right side. Anything shorter will not post or will post on the wrong side. I even made the two lines stop at EXACTLY the same X value, (Y in CAD, to 0.0000) and it would not work.
Made the line on the LEFT .01 longer than the right one.....BINGO ! EVERY TIME.
PLEASE try it and see what you get.
Chip, on your INNER sample, try it and let me know what YOU get.

Thanks Guys,
RC

Right, I finally got somewhere! I've spent a long & frustrating evening playing with bores. (boring in fact)
If you take a look at the attached test file, the rules seem to be that :
1/ point A must be further out than point C.
2/point B sets the start of cutting on the inner bore.
3/the zero marker sets X0

Bevels seem ok but arcs don't seem to work - although I've run out of steam for tonight.

See what you think

Tony

HA, RC - just beat me to it!
