Thanks all.

Sounds like a good idea to start with one axis.

With regard to the software, I upgraded to the latest version using:

$ sudo apt-get update
$ sudo apt-get dist-upgrade

Now the G-code from inkscape loads into plasmac, but the cutter does not probe down. It just cuts at it's homed height. I had this problem while making my own program and found that putting "M3 S1" before the first block of movement solved the issue.

Also, the material errors are still present. Interestingly, they open when the program launches (not when the G-code is loaded). Are the materials in a different file?

Thanks again.

Yes, M3 S1 is required for PlasmaC to begin the sequence.

Yes, there is a materials file which is first loaded on LinuxCNC startup.

Start from the Z axis, then bolt that to the other axis ( usually X ), then you get a general idea of how all that should be mounted and moved on the long axis.
If you start in the reverse order you quickly learn that theory and practice have huge differences, and you end up making compromises that will lead to reliability and limited functionality issues and so on.

Hello all.

I have tried to upgrade again using:

$ sudo apt-get update
$ sudo apt-get dist-upgrade

However now when I launch linuxcnc and click to run plasmac, Linuxcnc closes and I get an error message "Linuxcnc closed with an error". I have attached the error report.

Interestingly when I run a non plasmac option or even one of my old plasmac configurations from "my configurations" the program opens as normal.

Does anyone have any ideas?

Thanks.

You probably need to run the configurator in Upgrade mode after you upgrade LinuxCNC.

It is best done from a terminal to catch any errors.

I'm not so sure that the configurator will fix it based on my experience updating plasmac from master branch source code. But definitely run it.

This is the error
twopass: Error in file ./plasmac.hal:
    Pin 'spindle.1.on' does not exist

I had the same problem today.

So for the OP, just open plasmac.hal file and comment out the line containing spindle.1.on by prefacing the line with a '#'
This has been added to allow control of a pneumatic engraver using the multi spindle feature.

Phill, I think that if the engraver pins are not entered, this line should be commented out or omitted when running the configurator.

Yeah I didn't run make. Just the two commands I posted above.
Is there a specific command I should be using to do that?
Thanks.
