Having trouble getting LinuxCNC to find my M100 bash file.
Keep getting "unknown m code used" error message
Probably a path issue, do I add some sort of path info to ini file?

Hi
The file must be in the directory pointed to by PROGRAM_PREFIX= in the ini file
The path should be a full path not ~/xxx since only bash can expand the tilde, linuxcnc can not presently.
It must also be executable and remember that linux is case sensitive,
I always name my files with a capital M since that is how I write GCode, with all commands and axes in uppercase

Still not having success. The ini path statement looks good
PROGRAM_PREFIX = /home/me/linuxcnc/nc_files
The M100 file was a copy from the example M101 file
So I have recopied the example M101 file added my halcmd and saved it as
M100. Linuxcnc no longer gives me the unknown M code error.
But according to Hal Meter hm2_5i25.0.7i76.0.0.output-14 fails to become true.
The M100 file looks like this.
#!/bin/sh
# M100 in your G code program will run the Linux commands in this
# shell script "batch" file, passing the P and Q variables as command
# line arguments.
# give the command line arguments descriptive names
P=$1
Q=$2
#echo "M100 P$P Q$Q: put your code here"
halcmd setp hm2_5i25.0.7i76.0.0.output-14 <= TRUE
exit 0
Is there some Linux Voodoo that has to be done to permit a BASH file to run?

You can always try running the script by hand in a terminal:
cd /home/me/linuxcnc/nc_files
./M100
My guess is that the "<=" is not legal setp syntax or the M100 file is not executable
cd /home/me/linuxcnc/nc_files
./M100
My guess is that the "<=" is not legal setp syntax or the M100 file is not executable

setp only takes 2 arguments, first is the param or pin name and second is the value to set it to
The only place you can use => or <= is in net commands, which specifically ignore them
You also may not be able to access the pin anyway, open the Hal Configuration window and try out the command in the command box first

Yes you are correct The => or <= fouls things up however there is no error message generated.
By trial and error have found that in a bash file an expression like halcmd setp or2.0.in1 TRUE
works. But when or2.0 is loaded or2.0.in1 must not be linked to any thing in the Hal.
Thanks for the help guys
