I thought this was solved. Check your lathe.ini file to see where PROGRAM_PREFIX points. It can be a relative path to this file or absolute. Also you may try opening features before LinuxCNC.

I played with PROGRAM_PREFIX but couldn't get any change in behavior. If I start features.py before Linuxcnc (not exactly most convenient) it doesn't complain about this on startup, but if I try to use any of the features I still get this error.

If I select Lathe thread i get a G-Code error in features.ngc dialog that says:
Near line 54 of
/home/tom/linuxcnc-features/FernV.../scripts/features.ngc:
Spindle not turning in G76

I did not review lathe routines that I did not write like this one but I found some code was missing. I corrected that and pushed to git but it does not show although git on my computer says files are up to date. The file is ini/lathe/thread-adv.ini but if you want to correct it here how to do it simply :

1- in features do Add -> Threading -> Thread
2- in the table view select and right click on Lathe thread ??? or use Utilities Menu and select "Edit current feature" (it will open the file in your editor)
3- go at the end and replace everything after

[PARAM_FEED]
name = Feed
type = string
icon = icons/tool-feed.png
tool_tip = Feed
value = #<_global_feed>

with

[PARAM_SPINDLE]
name = Spindle Speed
type = int
icon = spindle.png
tool_tip = Spindle speed
value = 400

[CALL]
content =
#<p> = [#param_p]
#<k> = [#param_k]

G0 X#<_global_rappid>
G0 X[#param_x0]
G0 Z[#param_z0]

S#param_spindle M3

G76 P[#param_p] Z[#param_z] I[#param_i] J[#param_j] R[#param_r] K[#param_k] Q[#param_q] H[#param_h] E[#param_e] L[#param_l]

4- save the file
5- in features delete Lathe thread ???
6- reload it with Add -> Threading -> Thread
7- set params to have threads that are OK

Well, I made this edit, now when I select that feature I get nothing in the features window and a whole pile of errors in the terminal about parsing errors...

Hi Tom

Can you post the ini file you are using when starting linuxcnc ?

Hi Tom

Thanks for posting your config file.

./features.py:2897: GtkWarning: Failed to set text from markup due to error parsing markup: Error on line 2 char 42: Element 'markup' was closed, but the currently open element is 'D0'
return window.run()

The bug was in the header help of ini/lathe/thread-adv.ini

This following error was when it was not able to create the file (it also happenned with full path)
Unable to open file <./scripts/features.ngc>
I hope I solved it for good

About the last error you mention, make sure your file looks like ini/lathe/thread-adv.ini on github

I updated the modified files

There are not too many examples for lathe in linuxcnc/nc_files/examples and I had not much chance to play with it but I will do later.

BTW have you tried with mill config ?

P.S. So far, nothing interesting with gmoccapy

Hi Fernand,

I tested Features-V2 embedded in Gmoccapy (LinuxCNC 2.7).

1. Clone Git Repo " github.com/FernV/linuxcnc-features.git " into ~/
2. Copy all files from ~/linuxcnc/configs/sim.gmoccapy" into "~/linuxcnc-features
3. Make this settings in the ini file

[DISPLAY]
DISPLAY = gmoccapy
EMBED_TAB_NAME = features
EMBED_TAB_LOCATION = box_right
EMBED_TAB_COMMAND = gladevcp -x {XID} -U --catalog=mill features.ui

[RS274NGC]
SUBROUTINE_PATH = ./macros:./lib:./scripts

Hi Fernand,

How can i change from default inches to default metric?
