HI Willem:

 All youd have to do is put the feed/rev gcode in the post prelog box, and clkaim the feedrate as you wish it to be in units/rev..

 But eventually I'll add a checkbox for that..

Hi, Art

Hears a DXF that won't generate a rough except in Diagnostic Output mode.

Edit: last pic is for 2 post down.

CHIP,
I don't think that that Lazyturn is the problem with arc.3.dxf. I had problems with the file in all versions of Autocad and three versions of Microstation. I attached one of the error messages from autocad. Even if it was read, still couldn't save it to a usable form for import by Lazyturn.

Hi, Rich

It works with a horizontal line on the right end , arc, diagonal line Up or Dn, But not as pictered or with a vertical line or no line.

I promise I didn't use smoke and mirror's hear, Why are they loading in LazyTurn & LazyCam hear ?

It may be a newer version of dxf 14 that your cad's can't read properly, There not always backward compatible.

My BobCad v23 has been working just fine hear, Had some Droughts early on, But I'm starting to Question your Cad programs now, Rich.

Thanks, Chip 

Hi, Art & Rich

Hear are the 4 Dxf's for above Pic's.

Thanks, Chip

OK Chip,
F,E,D work here also.
Now C is still a challenge as to posting of roughs. Yes it will do a diagnostic output and also a limited posting if a z start offset offset is used as you have already shown. Redrew it so don't think it's anything on to do with our CAD stuff. Started trying some of the different rules i posted in post #474, but, maybe you found another one to be added to the list ( not sure what it is yet). I don't get any errors when importing C into ACAD 2007. I don't know why and need to get into work to try Microstation XML.

I can get C in Lazyturn to work but requires at least some kind of attached line ( even a horizontal one only 0.0001" long). Didn't go back to earlier versions to see if they would generate roughs. There are a lot of combinations you can come with in checking this out.
RICH

ART,
Here is a to TODO for Chip's Arc.3 dxf in reply #514. Only got it about 5 times out of 20 imports of the file.
Maybe you can shed some light on the last few posts. For the most part we have provided some type of line
or curve which provides for an x&y in the profile. Not any negative starting profiles even if in the correct
quadrant.

RICH

Ill check it out to see why... Been working on soem other issues.. New release shouldnt be too long..

Thanks Guys,
Chip,
 Looks like the rad at the end of the part cannot be tangent to the face. (if I'm saying that right)
I clipped enough off of the end of your arc so that it is not tangent to the end and it posts a path.
Might be a clue.
Thanks,
RC

HI Guys:

  The problem with the arc file is it starts with a decresing Y, l;eaving no tangent for the profiler. This is autofixed on load in this version.
Also, file close is added, and the box sizes for the numbers are better behaved, though maybe not perfectly. Sclaing in OpenGL is a bitch.

  This takes into accoutn a bit more in terms of pullouts.. and fixes a few other small items..

 Im working in the background now on a fine path, then the intermediate step "Rough/fine" will have to be done.

Thanks ( and Merry XMax)
