[REMAP FOR M6] Why does linuxcnc run the .ngc file on startup? was created by mugurlu
Hello,
Yes, really Why does linuxcnc run the .ngc file on startup?
(P1.png linuxcnc startup)
What I want to do is to run only when M6 command is given.
My other question is;
Why does it stay in No Tool status? (P3 ... P4.png P5.png)
Can you help with these issues?
Best regards,
mugurlu

Do you by any chance have an M6 in the [RS274NGC]STARTHUP_GCODES in the .ini file?

Not sure why it's running at startup.
But as to why you have a tool offset but no tool loaded:
In line 23 of your 'tool_change.ngc' you are only telling the controller to enable tool length compensation using the tool length offset value of the 'selected_tool' but you never actually tell the controller to change the tool.
Note that you can actually use M6 inside a custom remap:
Have a look at section 5.6 here:
linuxcnc.org/docs/html/remap/remap.html#...lated_codes_t_m6_m61
So maybe changing line 23 to this will do what you want:
T#<_selected_tool> M6 G43

caused an endless M6 loop!So maybe changing line 23 to this will do what you want:
T#<_selected_tool> M6 G4

Section :4. Upgrading an existing configuration for remapping
Create stdglue.py file.

I edited stdglue.py for two headers as below;
everything is fine so far
However,
I can't find the answer to the question in the title.
What should I do to prevent tool change every time the machine is turned on? (M6 why are you working?)

You have to test for milltask mode in ypur remap and return if it is not so it doesnt run the remap and move the machine. When Lcnc loads a file it is in preview mode. Thats the best way I can explain it. Maybe someone can chime in.
if self.task==0:

Unrelated: Note that the FEATURES tag in the [RS274NGC] Section does no longer work in Version 2.8 and up.
