Using beep with LinuxCNC M code

Using beep with LinuxCNC M code was created by Rick G
Beep is a neat little program that allows you to create a beep or a series of beeps on the PC speaker. You can control the frequency, number and length of these beeps.
Some computers that are used only for running LinuxCNC are stripped down with no speakers or sound cards, but they may have a PC speaker.
If you use a joypad, a pendant or some other input device for setting up new work you may not be looking at the screen when you hit a button. For example a button to switch from continuous to incremental jog, a button to switch from manual to MDI mode and "touch off" buttons. It is helpful to have some audible feedback to confirm what is happening.
You can access these beeps with M codes.
To install beep from the terminal.
sudo apt-get install beep
Information on beep can be found on the terminal by typing.
man beep
You may find that the PC speaker is blacklisted and could not be accessed so blacklist.conf may need to edited.
From the terminal.
sudo gedit
In gedit navigate to /etc/modprobe.d/blacklist.conf
Comment out the line
blacklist pcspkr
Save the file and reboot.
Beep will hopefully work now, to test from a terminal just type.
beep
You should hear a single beep on the PC speaker
If all is well you can now use M codes to create a beep, a series of beeps or even a song, for example pick an unused user definable M code in this case M105 and save it in the proper directory for your computer.
#M105
#beep charge
#! /bin/sh
beep -f 261.6 -l 300 -n -f 329.6 -l 275 -n -f 392.0 -l 250 -n -f 392.0 -l 250 -n -f 1 -l 300 -n -f 329.6 -l 300 -n -f 392.0 -l 350 -n -f 1 -l 400
exit 0
Then to hear it in LinuxCNC from the MDI window enter
M105
To hook this up to a button. In this example push the right stick down on a joypad for the first MDI command in the ini file. Substitute the correct M code, MDI command number and button for your set up.
In the [HALUI] section of your ini file add
MDI_COMMAND = M105
In the custom_postgui.hal add
net right_stick_down halui.mdi-command-00 <= input.0.btn-base6
Putting it all together...
Change your MDI command to do something useful such as.
MDI_COMMAND = G10 L20 P1 X-.125 M105
For G10 I use a single beep for X (beep -f 261.6 -l 300) , a double beep for Y, etc.
Use a button or combination of buttons on a joypad to call the sub called "home" for this I use M105.
o<home> sub
M105
(debug, CAUTION HIT RESUME TO RAPID MACHINE Z THEN X AND Y TO G53 0 POSITIONS)
M0 (pause)
M110
;raise z first then go home
G53 g0 z0
G53 g0 x0y0
o<home> endsub
M2
That should do it.

Thanks Rick, your instructions worked great.
I got my probe to beep when it makes contact. It is really cool now!
net renishaw hm2_5i25.0.7i84.0.1.input-06-not => motion.probe-input
net renishaw => halui.mdi-command-00 ## to make probe beep on contact ### see M198 , user defined m code ##
[HALUI]
# M198 probe beep on contact #
MDI_COMMAND = M198
M198 file
#!/bin/bash
# file to beep when probe touches -l= length -f= pitch frequency (not a halcmd)
beep -l 125 -f 400
exit 0

My machines are too loud for this, but very helpful information for a next project.
Thanks

That is a VERY handy, worthwhile, and appreciated effort. Thanks. I will most certainly be looking to use this in the near future.
