Error Recovery

Snowgoer, for the record, I've only ever used RIP and compile from source. I've always used master ever since 2.8 became the new master. If I want to run a different branch be it 2.8 or an experimental branch, I just check it out, make clean and recompile.

The only nuisance is having to run the rip-environment script

I've never bothered building the debs to get stuff installed in the menus typing linuxcnc -l will run the last config you've used and I have two desktop shortcuts that sets up the rip-environment and then opens Linuxcnc. One opens the chooser and the other has the -l switch to opens the last config used.

But most of the time I open it from a terminal window.

More recently, I've been hacking the interpreter hard to add more features so when I'm done and I work out how to get it over onto my own git, I can give you test projects galore!

Yea, I remember finding RIP a huge PITA a few months ago, but I've gotten used to it, and I think I prefer it now. It seems super useful for testing new stuff anyways.

Oh, new features? I'm intrigued. Can you elaborate on the "interpreter" this is a new piece of lingo for me...?

venture into the dark side of /src/emc/rs274ngc and be afraid!
I've been extending the functionality of state tags that recently made its way into master branch to add features that I think are good for plasma, then Andy made me add a heading for tangential knife alignment, then I thought of some more stuff and then... some docs and it goes on.

You can contact me here and we can discuss off forum. www.vmn.com.au/contact-us

Finally got some cut errors to play with this (I say that like it's a good thing haha).

Things I noticed:
1. It let me move the torch around by the kerf width the first time the program would pause. But if I got an error on the next attempt, it wouldnt let me move the torch around anymore.
2. The pause stuff no longer works the way I used to remember, I could sometimes execute the next line (which was to turn the velocity back to 100%), but I could never get it to execute line to start the rapid motion to go to the next hole. This would be when it would arc-out at the end of the cut. I was unable to get it to keep going through the code to go to the next feature and start cutting again.

I attached the cut file for if it helps at all.

Unrelated to cut-recovery: I thought CPA mode worked independent of "arc-ok". I couldn't get it to stop flaming out at the end of the cut... I thought that was the point of CPA mode, to keep moving independent of the torch arc? Or am I missing something?

Can you define CPA mode? I'm lost.

Continuous Pilot Arc. From the Hypertherm manual "For cutting expanded metal, grates, metal containing holes, or any job that requires a continuous pilot arc. Using this mode to cut standard metal plate reduces consumable life."

My understanding was it made the "Arc-OK" true with the pilot arc so that you could cut corrugated materials, perhaps I'm mistaken.

Not for Corrugation but for mesh and other perforated material. I wonder if there needs to be a mode to disable ArcOK sensing?

Corrugated Iron is as per normal but requires a Z velocity fast enough to follow the contour at the cut velocity under THC control. This may mean that your max cut velocity is constrained by the Z performance. I've been keeping a bit for a glorious Youtube trial.

Sorry I didn’t mean corrugated, I did mean perforated... long weekend..

I read that in the manual as well. But I don't think PlasmaC caters for that at this time:)

Maybe when it is in CPA mode PlasmaC needs to disable THC.

I have no clue whether the machine keeps Arc OK on or not while in CPA mode..

My machine only uses CPA mode but it doesn't have Arc OK so I cannot test it out.
