LazyCam (Beta) / Re: LC never produces valid GCode

Thanks Rich,
with your dxf I'm able to reproduce at least 2 passes. I've choosen a tool with 3mm dia and the rest as in your screenshot. My depth per pass is 1 and my cut depth is -10. The result is two passes but should be 10. Perhaps it has to do with the rapid height which is 5 in my setup. Every change in those parameters does not lead to different results.
Just to mention it: my material is 60 by 60 by 10 mm. The Z0 is on top of the material surface. The tool is 3mm and has to go 10mm deep (to Z-10). As it can go 0,25mm per pass, it should need 40 passes.
Now I had about 40 tries but none of it produced g-code with more than 2 passes. I give up on that point.
Another issue is with my dxf. As already mentioned it comes out of TurboCAD 5 Mac and it is in some unknown way different than Rich's dxf. Don't know why. Even if I put the lines and the circles in different layers - after it was in LC, only one circle appears in Mach3. The others are all missing.
@RICH: I realized the red lines in Z direction - do they have a special purpose or are those only helpers?
@Tweakie: There should be no difference. See above. Thanks for the hint - I insert the G42 manually.
Ok, that's enough for now and my spare time is used up. Thanks everybody for helping. I'll be trying LC when it got out of beta. I've just learned g-code and will do this with Notepad.
Thanks
Hoagie
