Using fusion 360 for post processing, not getting a pierce delay. I put it up to 4 second for testing purposes and it definitely isn’t waiting 4 seconds. I’m not seeing a pierce delay in the g code either. Trying to cut 1/4" so I’m really noticing the lack of pierce delay. Any ideas?
post the g code lets see what is going on.
It’s in there. G4 P0.5. That’s a .5 second delay after the M3 torch fire command.
That makes sense now, I was thinking it should say (Pierce Delay). Is there a breakdown on the g code lines so I can know what each line means? Also I’m pretty sure I figured out why I was getting .5 second delay instead of the increased delay I was setting it to. I was inputing the delay into the torch settings when I would build a torch profile for the different materials I would be cutting. I did see the pierce delay setting again in the post processing screen, it was at .5 seconds… What is the purpose of these settings when you build a torch profile if they don’t actually affect the g code?
here is a bit of a break down
here is the g code for this
Here is that code where I explain each Line that cut out the middle circle.

I was wondering the same thing some time ago and started a post at the autodesk.
maybe one day they will inform the post processor ?

It would be really nice to have different profiles that were dialed for different materials. Guess I will just have to write down on my note pad for now.
You can do that in Sheetcam. Create a tool for every type and thickness of material.
I think I will look into sheetcam, thanks.

In Fusion everything but the pierce delay and cut/pierce height has to be added at the end and the other settings can to saved.
SheetCAM is definitely easier for a lot of folks.
I just hate to lose the parametric connection between manufacturing and design by moving it to Sheetcam.
You may lose 15 seconds updating those few pieces of tool data in Fusion 360 but if you have to make one design change in SheetCAM you have to backtrack to your CAD software and lose time too.
