How do I change the direction of cut? - CNCzone.com-The Largest Machinist Community on the net!

Ironworks · #1 05-07-2009, 10:10 AM

I need to change the cut direction on a single line. I understand that the software knows which direction the line was drawn, and it cuts in that direction. I need to switch it to the opposite direction. Any thoughts on how to do that??

Thanks!

what is the G-Code your post processor wrote for that line?

I've attached the DXF file...

The line in your DXF is a spline. But none the less are you cutting on center or are you using G41 or G42 ?
I have to convert splines to a poly line before I can cut. Do you also or can you cut Splines on your machine?

Sorry, I don't know what G41 or G42 means. I don't even know how to find out...

Ok I guess I jumped on this post too quickly. I didn't realize you are running a torch machine. I see that only after your response. You must be cutting on center of the line. Do you use software to program this machine? If so , it should be easy to reverse the cut directon. Or does this machine take a DXF file directly into it and uses that file alone to cut? I'm not that savy on torch or Plasma cutters. I've never seen what your G-code looks like or even if you use a G-Code. You may use Binary code ? ?

Thanks for trying to help. This is a PlasmaCAM machine, using their software. I have not been able to find anything in there software that lets you change direction. BUMMER!!

Another suggestion....when I do a mirror image it reverses the tool path and cuts in the other direction. Have you tried this?

Ironworks · #9 05-07-2009, 04:47 PM

I just tried mirror -- no change in direction.

Ironworks,
What software do you use? I use sheetcam software and it can change in opposite direction. It's easy if you use this software. Don't worry for post processor for G-code. It has the post processor for plasmacam as well.

Thanks for the suggestion, Mongkol. I'm downloading it now...

Ironworks,
Is it possible to share the software of plasmacam? I want to compare with my sheetcam. Which is better than?
