Hi,

I did all the steps described on the github repo when I installed the stuff.
Everything now is working, but I am unable to produce output.
Neither in standalone version, nor in axis ui embedded tab.
I suppose the reason should be quite simple and the same for both cases.

In standalone version I can save only the XML file, but not the NGC.
In axis embedded ui nothing happens when I push Refresh button.

This is the error message I get on the console:

System is ubuntu 12.04, with python 2.7 (/usr/lib/pymodules/python2.7/gladevcp)
LinuxCNC is buildbot 2.7.0 master

Thank you for your help in advance.

Best regards

It needs ini file to find where to put output...
try to

To use LinuxCNC Features in stand alone mode, just start them after you have started LinuxCNC providing path to your LinuxCNC ini file in --ini parameter

and your ini must have SUBROUTINES_PATH parameter.

Hi,

I added SUBROUTINES_PATH to ini file in RS247NGC section, but still no luck. See the output below

I am confused, because NGCGUI requires SUBROUTINE_PATH (without "S" ). Are those stanzas the same?

cat /home/bj/linuxcnc/configs/sim.axis/axis_mm.ini | grep SUBROUTINES
SUBROUTINES_PATH = /home/bj/linuxcnc/linuxcnc-features-master/subroutines

Simply displayed g-code file is not generated as expected.
This is due to the fact that the global variables in processing are not initialized
Try to start the most simple processing - the circle or hexagon.

These treatments should be added and filled at the beginning

Hi,

I tried to make it according to your recommendations.



I checked several videos, but can't figure out what is wrong...

Are you want to use lathe or mill processing?

Hi,

I downloaded the latest linuxcnc-features, installed it and now it works.
I don't know what I messed up with the 2-3 month old previous version.

Thank you very much for your effert you tried to find out the cause of my issue.
Also big thank for the great linuxcnc-features tool.

Best regards:
