Rodw,

I have to think about opinion for a while. It's a nice thought anyway !!
My current opinion is to stay with the orginal linuxcnc version for plasma, like Toma Thc or PlasmaC.

Splitting up core code for enabling gcode variants will not make thing's better on long therm.
Cam code is for this thing's. If we wan't cam options into linuxcnc package. It's fine for me.
What do you need? B)

Phill,

I have read the overcut depend's on enabling factor 2. But i see not how the overcut is done.
It looks a impossible job to me that linucnc can do a overcut for all contour's at this moment. Linuxcnc is not a cam package and
has almost no logic about cam on board.

Pedro,

Grijalvap has the credit's. He has provided the Python Hyperterm Modbuss interface for LInuxcnc a while ago.
Thanks for that Pedro. I don't use it anymore. But it's nice to have.

Just a guess but the name of material18 has a space and is the longest so far

It was a great weekend, discovering all the PlasmaC features and benefits, I can't wait to install on a real machine
thanks for this awesome component.


Great feedback Pedro. Some of your pioneering work has found its way into tPlasmac thats for certain so thanks for that too!

After material 17 everything is blank.
I have 78 entries, is there a limit to the amount that can be shown?
I attached my material .cfg file as a text file (allowed attachment).

It is material parameters for a Hypertherm PMX 85.
I converted it from a microsoft Exel file. Do I need to install it with Materialverter?


I have over 50 entries in my cut settings so it must be your config. The only thing I would say is when selecting material from Gcode, you will need to wait longer with M66 than the examples to find your cut setting. I use 2 seconds. Materialverter is not going to help you but you may have given Phill an idea to support a CSV file import.

Pretty sure Phill is running the gcode through a filter written in Python as you open a gcode file. Just one more hidden feature linuxcnc has tucked away...

Just a guess but the name of material18 has a space and is the longest so far

I found the problem, material 18 edge pierce was the first material that had a missing parameter, pierce height and peirce delay were blank.
Thanks,

Thanks for the report, it looks like I should add some sort of error checking.

It is done by the GCode parser and only does full circles at this stage.

Yes, I found that today but haven't pushed the fix yet.

If you use the code I posted for you to try here it will fix it as well.

If you just want a quick fix change line 279 of plasmac_gcode.py

from:
            a,b = line.strip().split('(')

to:
            a,b = line.strip().split('(', 1)
