Another plasma component...

I am using a post processor posted by John in this thread a while ago,

I have the sheetcam rules set as per this picture,


I will check that file out tomorrow as the machine is cutting at the moment.

OK, I also ran that ngc file with #<pierce-only = 1 and it seemed to work as well, 364 pierces...

EDIT: I just noticed your code says DHTC-OFF, should that be something else? I know nothing about SheetCam

No, DTHC-OFF is telling the controller to turn off the digital torch height control for the hole.

So it must be something in the Post processor that is causing it to not output M67 feed-rate code? Or could it be that it was never set up to do that in the first place. Just thinking about it and all of the parts I have cut up until this point I did not need decent holes so I must not of noticed it.

Sorry I can't help with that, but it may have had something to do with the problem you mentioned about some holes earlier on.

Hopefully Rod or John will chime in.

Stefan, Can you try the post processor I shared here:
forum.linuxcnc.org/plasma-laser/36568-po...smac?start=80#139099

I don't think I made any changes since.

I installed the latest master branch (RIP) yesterday and have encountered a couple of new features that are causing me problems.

1. When I change the material from Gcode the program pauses every time. The optional pause on M1 is set to off on the GUI. This is not good when you have several materials per part and a whole sheet of parts. On further testing this maybe a Gmoccapy 3.0.X problem because it occurs regardless of the state of the optional pause button on the GUI.

2. The Gcode parser is adding an extra ) at the end of the last comment in the file. This is causing a loading error the requires editing the file using the built in editor to remove the extra ) and saving the file. Again usable but a PITA. The removal of spaces and forcing lower case in comments makes reading difficult for old guys.

Please find attached a file that cause both to happen.

Update

Issue 1 is normal behavior for Gmoccapy 3.0.7.1 so I fixed my PP so it will not post M1 optional stops. Issue 2 was fixed by downloading and updating new files this afternoon.
