LinuxCNC Features - a kind of NGCGUI

Thanks Marius

I will look at it and include it for sure when I have it working well

Hi,

You can now download and test a new advanced version of Linuxcnc-features at
fernv.github.io/linuxcnc-features

Cool, looking at it now...

When I start it (standalone) I get an error that says:

G-Code error in features.ngc
Near line 62 of /home/tom/linuxcnc/features/FernV-linuxcnc-features-ba61fd6/scripts/features.ngc: Bad character 'y' used

Is this because it comes up in mill mode (using a y axis) and I am running a lathe? Anyway if I click ok the window comes up as it should...
-Tom

PS:
This error comes up in the terminal where I start Axis:
emc/task/emctask.cc 389: interp_error: Unable to open file <./scripts/features.ngc>
Unable to open file <./scripts/features.ngc>
can't open ./scripts/features.ngc

And this error comes up in the terminal where I start features.py:
tom@EMCO-120P:~/linuxcnc-features/FernV-linuxcnc-features-ba61fd6$ ./features.py
./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()


PPS:
No matter what I do in Features I get an error in Axis that says:
Unable to open file <./scripts/features.ngc>
can't open ./scripts/features.ngc

PPPS:
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

When this happen, in LinuxCNC open File menu and select Edit file. In the editor (maybe gedit it depends on your configuration) look at the specified line to understand what is wrong

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.

It looks like a markup text somewhere is not right, something like <b><i>Display text</b></i> instead of <b><i>Display text</i></b>

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

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

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.

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.

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?
