Hi:

  For all intents and purposes there is no real good reason, a radius of .0005 is effectively 0.0 in real world terms. It means an error tolerance of .001 ( inch or mm) in a
profile, so it has no real effect. Internally however, I just have to ensure low values are treated fairly for the sake of stability.
  Questions like this one go to stability in the end, and the theory of "If they CAN break it, they WILL" , which is somethign I have learned over the past
few years. It was my decision early on in LTurn to allow for this, and to profit from it by allowing it to be broken, shut off each avenue as I can, and then
I wont have to worry so much about support. In Mach3 I quite often use the axiom that "If it hurts to laugh,..dont laugh.." , but in LazyTurn I want people
to go ahead and break it if they like, if I can shut off that door, I will, and hopefully we'l have much less support questions from things that shouldnt be done, because internally
the program will correct whats wrong before you see it.

One of the reasons for example that more files now load, is that I change them as they come in , or just tell
you that they wont load. The program now "AutoTolerates" so that lines that dont join, automatically stitch
together as long as it doesnt create discontinuities in the math functions. This means the program will try a
 tolerance of .1 for example, and if it finds that this creates a conflict, it will jump back and set the toleance
to .01 and try again, then .001 etc.. until it either solves the problem, or rejects the file.

  By the time LazyTurn is complete, I will be very well armed to tackle some of these type of issues in LazyCam
which suffers greatly from tolerance issues. These sort of notifications therefore go toward educating me on the issues,
and even if they sound kinda crazy at times, they actuall do have their place in the scheme of things.

miniature world of turning you will actually use a point tool and that tool will not look like any conventional tool.
Maybe a better way of saying it "you got the  gcode......the tool is up to you".

I think that this is a great point and should at least be considered.

If Art can do it without losing his mind (!), then great, but if it's going to kill things, I don't see it as a deal breaker either.

Thanks again for all you do, fellas.

Would envison that there will be more problems with folks not being able to machine to
dimension because their machine system isn't capable than something generated from Lazyturn.

Three generic gcode test programs for the lathe should easliy put that in perspective, namely:
- One for X axis movement, one for Z axis movement, and one for a combination move.
Number of combination move loops would be equal to:
STOCK REMOVAL THICKNESS / SMALLEST CUT x 4  

This post off thread, but it just comes to mind.
RICH

A lot of users like to think their machine is more accurate than it actually is, but there are a few that do seem to have very accurate small machines.
I would think that as far as the software goes it shouldn't mind working with tight tolarances as it's based around maths so you should be able to work with very small numbers.

While I'll be very happy to have my mill machine to within 0.01mm one day I don't think it's asking a decent lathe too much to do that normally.

ART, RICH.....Thanks for the explanations.
I guess what prompted my question was reply 436 where Rich was seemingly requesting a tip rad. of .001 where Dec9.zip just prior allowed a setting of .0005   I just assumed that would be adequate and ART could move on to whatever would be next.

The more BULLET PROOF the better.

Thanks guys,
RC

Here is a strangeness.
The X pointers have no color, the Z ones do ....in the normal view.
Flip the display and the opposite is true.
Is this just mine ? Or do any of you see the same ?

I have red brown and blue showing for the X and green and yellow showing for the Z.

When you flip the view, they're the same colors.

Dave

EDIT: you see my rulers on both sides as well.

Thanks Dave.  Mine used to be fine...like yours.
Must have worn it out ....or rubbed the paint off anyway.
See Ya,

Hi, Art

Hears a dxf problem file, Loads fine on my other Cad software.

In LazyTurn it's not scaled correct.

Edit: This file will load in LazyCam Turn and post sii Pic's in next Post, Last 2 Pic's.

Art, Your statement: ( By the time LazyTurn is complete, I will be very well armed to tackle some of these type of issues in LazyCam
which suffers greatly from tolerance issues. These sort of notifications therefore go toward educating me on the issues,
and even if they sound kinda crazy at times, they actuall do have their place in the scheme of things.)

Your statement is so true, LazyCam Mill....Turn, Were getting very close, Just some final bug's for the most part, Turn may have had some additional technical issues.

But as a overview are very Nice !!

Thanks, Chip

Hi, Art

This one is fine, Something to compare to.

Thanks, Chip
