LinuxCNC plasma / laser post processor

[Anonymous]

I am using Fusion 360 and LinuxCNC for a plasma that I built, but I couldn't find a post processor... so I ended up modifying an existing one.   I'm not a programmer and I'm sure there are errors with this file, but I thought I would post this and give someone more knowledgeable than me a starting point.

I have noticed a problem that when there are multiple parts to cut out (in an array for example), it doesn't turn off the plasma or laser in between... so you end up with some extra cuts that you don't want.  I don't have that many duplicate parts to cut out so I just go in and add a few M5 codes manually.  That works, but it would be nice if the post processor managed it properly.

Hello,

Thanks for posting. I've just tested your post processor and unfortunately, i'm not able to replicate this issue? The torch turns off after each cut

Would you mind sharing a file where you can see this issue?

Cheers

Here is the f3d file as well as the G code that generated when I ran the file.  I'm new to this so I wouldn't be surprised if I'm doing something wrong in Fusion.

Thanks!

You specify Clearance and Retract heights of 0 (no retracts between moves).  A Power Off command is not issued in this case.  Adding a small Clearance or Retract height will cause the Power Off command to be generated.  The Single Setup does have clearance/retract values and does turn off the power.

That was it.  Thank you.
