Change default path following to G61? was created by rogerxue

Is there a way to change the default path following mode to exact? i.e. G61 instead of the blend mode?

thanks

Yes, have each G code program have a good preamble to set up the environment as you need it.

thanks for the reply, is there a place I can put the preamble in so each file don't need to have it?

Well you could have a subroutine with the preamble and call it at the start of each G code file.

I found this: linuxcnc.org/docs/2.6/html/config/ini_co...sub:RS274NGC-section
seems it is the right place to put the preamble ?
It says: "This is not a substitute for specifying modal g-codes at the top of each ngc file" does that mean each file can override the preamble?

Exactly, never rely on the settings to be as you want after you run a G code file. Always put the preamble in each G code file.

makes sense, but it would be nice to have a fall back default value, in case I forgot to include anything in the G file. In my case, I want to use G61 instead of the default blend mode. Is the RS274NGC the right place to put the default value?

If you forget to put it in the first G-code file of the day then the INI file section will work.
But after you have run G-code, all bets are off about machine state.

One thing that could be done, that would always work. You could create a script that inserts the line or lines of G-code you want at the start of every file when it is loaded. If you needed different settings in a file, having those codes already in the file, would override the inserted codes for that file, as they would be executed after the inserted codes.
