Hi all,

After successfully add rpm displaying in Gmoccapy, i am continuing the build of my Emco Lathe machine.
I was away from honeymoon and now i got some time again to work on the lathe.

At the moment i am struggling to get it to work.

In the INI file i got
USER_M_PATH = (*specific map where my M-codes scripts are)

The executable files
--M101--
#!/bin/bash
# opens the collet closer
halcmd setp or2.1.in1 false
sleep 0.5
exit 0

--M102--
#!/bin/bash
# close the collet closer
halcmd setp or2.1.in1 true
sleep 0.5
exit 0

I even tried a m-code scripts like this for both
#!/bin/bash
# close the collet closer
halcmd sets user_m101m102code 0
sleep 0.5
exit 0

In my Hal File
# --- M101 and M102 signal ---

loadrt or2 count=2
addf or2.1 servo-thread

net collet-closer-pedal hm2_7i76e.0.7i76.0.0.input-16 => or2.1.in0
net user_m101m102code => or2.1.in1

net collet-open-close or2.1.out => hm2_7i76e.0.7i76.0.0.output-15

What am i doing wrong here?

I got no error message when executing the M-codes in MDI. While i am doing that, i watch output pin 15 in halshow.

So far, nothing is happening.

I just tested your M101 and M102 and they turn off and on or2.1.in1 and or2.1.out turns on and off as expected.

linuxcnc.org/docs/2.7/html/config/ini-co...ml#_rs274ngc_section

USER_M_PATH = myfuncs:/tmp/mcodes:experimentalmcodes - Specifies a list of colon (:) separated directories for user defined functions. Directories are specified relative to the current directory for the ini file or as absolute paths. The list must contain no intervening whitespace.

A search is made for each possible user defined function, typically (M100-M199). The search order is:
1. [DISPLAY]PROGRAM_PREFIX (if specified)
2. If [DISPLAY]PROGRAM_PREFIX is not specified, search the default location: nc_files
3. Then search each directory in the list [RS274NGC]USER_M_PATH

The first executable M1xx found in the search is used for each M1xx.

Do you have a M101 and M102 in the nc_files directory?

In my ini file i got underneath [RS274NGC] the line USER_M_PATH with the direction to => /home/emco/linuxcnc/configs/EMCOTURN220/M-codes/

In the folder M-codes i got the two files that got the name M101 and M102.

Both are selected as executable file.

So why wouldn't hm2_7i76e.0.7i76.0.0.output-15 be triggerd? (in halshow it stays dark red)

I have to guess that net user_m101m102code => or2.1.in1 is blocking the setp or2.1.in1.

If you run LinuxCNC from a terminal you will see this error

<commandline>:0: pin 'or2.1.in1' is connected to a signal

When in doubt run from a terminal so you can see all the errors.

Thanks!!

i am not sure what really cause the problem, but it works perfectly now!
I made the m code scripts again, but changed the True and False to a 1 and 0.
I will share my files soon for those who would like to use it for something similar.
