Weird conversion issue?

[TheRustinator]

Hopefully someone has had this issue before.
I'm trying to cut this little fleur de lis style outline for a sort of brand (for wood), and I've been successful getting it traced from a drawing (in Inkscape), but when I try to cut it, it doesn't cut the left side out. I can't figure out what I've done wrong.
My process is:
Start with the .jpeg
Trace in Inkscape
Export as .DXF
Load .DXF into LazyCam
convert to GCode (.TAP file)
Run GCode through Mach3
Cut starts great but then ends like this.

The machine DOES follow the cut path for the part that it doesn't cut out, but the plasma doesn't turn on other than just piercing the cut.
I appreciate any ideas!

Perhaps post your g-code file here. Since it isn't cutting that particular feature - I would say that either you are running out of air to your plasma cutter (assuming that is the last feature in the cut sequence) or the M-code to fire your torch is missing from that last g-code sequence.

Can you try to erase that left side cutout and mirror the right side that is cutting and see if that works.
Or check to be sure that the left side is closed polyline?

It appears as though it is piercing the missing cutout but not completing the cut. In terms of cut order when is that profile cut? Is it the first cut?

I agree with David on the loss of air pressure, If you good with the G-code you can place a pause action after each cut to give the compress time to catch up. Create a code snippet under tools use the code M01 for the pause in the G-code. just hit cycle start after the pause to restart the G-code each time.

Thanks everyone! I checked the air pressure and it seemed fine. I'm running an 80 gallon 5hp compressor, so it looked like that wasnt the issue. I then ran the program, watched the cut, and paused when it stalled at the part that it pierced but didn't cut. I went into the GCode and copied the command for "Torch on", put it in the code after the pierce, and it worked!
I feel like a computer hacker now
Thanks again everyone

Rusty - that's great news that you have found the problem. The next question is: what can you do to possibly edit your post processor so that it does insert the correct code after the pierce for future projects? Or was this simply an one-time "glitch"?

That is great news, clever to figure out that fix. Like David I am curious if this was a one time glitch or if you find you have to do this with all your files.
