John, I'd keep the new build in a plasmac folder at the same level as linuxcnc-dev, not below it.
Sounds like the Aussie team has got you covered with after hours support on a Sunday!

When you do get it working there are two ways you can use reverse-run.
Note that reverse-run only operates when the program is paused.
1. Issue a AUTO_REVERSE command to the python interface then unpause and the machine will run in reverse, pause when you get to where you want then issue a AUTO_FORWARD to prepare for forward motion.
The standard Axis GUI in the plasmac branch does this with 'R' and 'F' as shortcuts.
2. Use adaptive feed:
To enable this you need to have M52P1 in your gcode.
While paused issue a negative value to the motion.adaptiveāfeed pin to reverse or a positive value for forward.
The commanded velocity is multiplied by this value.
Valid values are between 1 and -1 inclusive.
Cheers, Phill

Thank you for the tips. I will try to clone and build your branch today.
What happens when you reverse to a subroutine in the Gcode? My code is full of them because my config doesn't contain a fancy component with a state machine.

Well it was pretty painless to clone and build your linuxcnc-plasmac branch. I tried to do some a quick test with the gmoccapy-imperial sim and came up with several iterations of this error:
as well as the classic gmoccapy error:
So right now I am missing plasma screens when gmoccapy starts. I will look at this later when I get a chance, as many times as I have caused startup errors in gmoccapy this is a new one on me.

The error is due to a python library not installed. Th import command where the error is is Python's way of loading a library.
Try typing this on the commnad lineand/orRefer pypi.org/project/python-xlib/
Try typing this on the commnad line
pip install python-xlibpython setup.py install

Hopefully Rod is right about the Gmoccapy problem. I have no experience with Gmoccapy, I just did that sim to see if it would work and it ran ok on my machine.
The squares and circles demo gcodes have repeat subroutines and work fine.
Cheers, Phill.

Guys
Thanks for the hints, I was out welding up "garden picks" we sell all afternoon. I will start a new topic in the Plasmac thread as we are quickly moving away from Gmoccapy specific discussion.
