Loading M codes at startup: interp_error. Bug? was created by DaBit
It is possible to setup default G-codes in the INI file using the [RS274NGC]RS274NGC_STARTUP_CODE entry.
But when I enter M codes there, such as M53 P1 LinuxCNC crashes. Or at least the gmoccapy GUI does; that is just a blank window.
The actual startup code line is:
RS274NGC_STARTUP_CODE = G18 G64P0.01 G90 G92.1 G7 M53P1
This results in:
Problem seems more 'mutliple P words' than the actual M code. Not sure if this is a bug or not.
Is there an easy workaround?
System is stock Debian from the ISO with LinuxCNC 2.7.4

The order of words in a G-code block is not considered when parsing the block.
One side-effect of this is that the interpreter has no way to know which P-number to pass to which command.
You may have to make your RS274NGC_STARTUP_CODE into a subroutine call which splits the G64 and M53 onto different lines.
I don't know what happens if you have more than one RS274NGC_STARTUP_CODE line. It might be worth experimenting.
for example.
