radius/diameter programming and hal

ok I use 2.8... maybe that's why
I will try to search for the 'gcodes' file on my PC to understand this functionality a little better

Documentation for the python interface:
linuxcnc.org/docs/2.8/html/config/python-interface.html

As I said, start your config from the console and check for error messages.

As of the 2.9.2 update the gmoccapy.py file has disappeared. I can't find it anywhere. Have things been changed? It still loads up...sooo?
What happened? Or am I missing something simple?

open a terminal and see what this command reports:

find ./ -type f -name gmoccapy.py

[edit]

If you have not built LinuxCNC on your computer then you may need to search in the root directory:

cd /
sudo find ./ -type f -name gmoccapy.py

 

after a night of rest for the machine, this morning it works... mysteries of faith...
I did some testing by opening linuxcnc from the terminal and tried to understand what's in gcodes and made a small table:
[0] -> I don't know
[1] -> modal group G0 - G3 and G80 - G89
[2] -> modal commands, -1 when called modal command
[3] -> modal group G17 G18
[4] -> modal group G40 - G42.1
[5] -> modal group G20,G21
[6] -> modal group G90 G91
[7] -> modal group G93 - G95
[8] -> modal group G54 - G59.3
[9] -> modal group G43 - G49
[10] -> modal group G98 G99
[11] -> modal group G61 - G64
[12] -> I don't know
[13] -> modal group G96 G97
[14] -> modal group G90.1 G91.1
[15] -> modal group G7 G8

Aciera:
I get the following:

/ $ sudo find ./ -type f -name gmoccapy.py
find: '/run/user/1000/doc': Permission denied
find: '/run/user/1000/gvfs': Permission denied
/ $ cd run/user/1000/gvfs
/ $ /run/user/1000/gvfs dir (seems to do nothing)
/ $ /run/user/1000/gvfs sudo dir
dir: cannot open directory '.': Permission denied

previously it wasn't this hidden
Is something screwed up?

I believe so. Downloaded, burned to a card, then installed linuxcnc. Everything was fine until the beginning of January when the desktop said Updates available...I said ok, and everything went to ....well not a happy place.
I come from dos, so linux has me at a disadvantage.

This is normal, It's just telling you that it could not look for the file (ie gmoccapy.py) on the network drives.
Try this (note the removed '.py'):

/ $ sudo find ./ -type f -name gmoccapy

It finds a number of gmoccapy's but not .py . (a lot of .mo 's what ever they are)
So just what directory is it SUPPOSED to be in?
and....network drives.....where did they come from? In an RPI4?
