Maximum size?
« on: December 29, 2016, 02:10:47 PM »
I am looking to use Lazy Turn to turn a piece that is 48" long in wood. I am having a terrible time getting the dxf's into Lazy Turn, have I exceeded some unwritten limit?

Not that I know of.

If you read the manual you will see information on dxf files and how the drawings should be created.

Post your dxf file.

This is the dxf I am wanting to use. It was created in AutoCad and saved as v12 dxf. I am still learning how to create this in the middle of my stock.

I believe I followed all of the rules for drawing creation.

Try the attached dxf file.
I attached some pathing screen shots from the attached dxf.

What magic did you use so I can duplicate the process?

No magic at all.
1. I saved your dxf and converted it to 2007 ACAD which I use.
    The image was mirrored about the vertical.
    Then added a radius .002" at all the sharp points pointing inward to the stock.
    Next I saved the file as a version 12 dxf.
    
2. One needs to be practical when creating a profile such that a tool can actually cut the profile.
    ie; The reason for the 0.002" radius was so that a 0.001" wide tool could cut it, but practically speaking, no such a tool exists!

3. Then I just did a roughing and a finish pathing.

4. To quickly see the pathing you just use the scan line diagnostics. Else if you don't you may need to waite quite long as there is a lot
    of tool paths being created depending on settings for the profile cut. If the pathing suites your needs then create a profile paths.

5. Please read the manual, don't hack the program. It's  all in the manual and that is why I wrote the thing.

I like when mommy reads to me at bedtime, I can't since I can only write!  ::)

See Appendix B in the manual and note the following drafting errors:
3.5 and 5.10.

I forgot to list in item 1.0 in reply #6 that the polyline was exploded.

Thank you for your wisdom. I use the autocad join to insure no gaps in the drawing, just didn't realize a zero width polyline is still a polyline. Back in the manual, I understand the right and left cut direction. I believe in order to make the cuts bi-directional the toolpaths need to be interlaced, the simulation runs one toolpath before running the second which I believe defeats the intended use.

All I can say that LT is what it is and will not be enhanced or updated.
BUT.....as a FREE program for the lathe used within what it was intended to accomplish.........it serves the needs of many.
