Startup Code

Hello.

Try as I might I cannot change or adjust the G Code with which Gmoccapy starts with.




I have tried various things including changing the startup code section (below) of the ini file, but with no success.

[RS274NGC]
STARTUP_CODE =


I wonder if someone could steer me in the right direction to modify the start code for my circumstances.

As a matter of interest, from a file, I have run some other G code, and the modal starting codes of that file have no effect on changing the illustrated section of Gmoccapy either (although I am not sure if they should?), but I assume the modal codes during the running of the G code file are active behind the scenes and supersede the code listed in Gmoccapy shown above??

With thanks,
Marty.

I am pretty sure that code is set in your .ini file.

Thanks for the reply.
I thought the same and the documentation seems to suggest this. I changed the

[RS274NGC]
STARTUP_CODE =

section of the ini file which made no change to the code listed on the screen at start up.
IN fact at the moment there is nothing in my ini file which lists any G or M code at all, yet gmoccapy is still displaying code on its screen at start up, per the picture in the first post.

I wonder if someone could shed more light on this. Does the ini file possibly direct to another file which stores the start up code, the link to which I have missed?

Thanks!
Cheers,
Marty.

According to the documentation this should be:
[RS274NGC]
RS274NGC_STARTUP_CODE = ...

linuxcnc.org/docs/devel/html/config/ini-...ml#_rs274ngc_section

I checked on sim config, works well.

Please keep in mind too what Andy replied .

Have just finished checking and you are correct!

The parameter needs "RS274NGC_" in front of it to function and secondly, the changes are very subtle because as you say, to check functionality one must change the codes which are required with the other options in its modal class. Otherwise gmocchapy is smart enough to provide its own default values in lieu, which for a time had me wondering given that this behavior seemed to mask any ad-hoc changes I was making at the "Startup Code" input end...

Very interesting and thanks again for the guidance.
Regards,
Marty.
