Ah.
https://github.com/LinuxCNC/linuxcnc/blob/master/src/emc/usr_intf/emcrsh.cc
It uses sockets in that file which implies this is how communications is done.
But as usual, the code is quite vague. For example there's this function.
static cmdResponseType setSpindle(char *s, connectionRecType
If you look at the axis source code, to increment the spindle you call...
c.spindle(linuxcnc.SPINDLE_INCREASE)
where
c = linuxcnc.command()
linuxcnc.command() comes from halui.cc (I think), which sends a message...
static int sendSpindleIncrease(int spindle)
{
EMC_SPINDLE_INCREASE
Let's say you wanted to access the hal pins and essentially run the machine
using a different programming language like C instead of python.
How's the linkage done from say the Axis GUI to the rest of the system? Like
Spindle ON button and then Spindle +

If you are running PathPilot, I'm guessing your distribution is from
Tormach, so the environment variables may already be set up.
Just try it. If it doesn't work, you should get error messages.

I think you just need to "import linuxcnc" to get access to linuxcnc
command and state.
But you would probably still need to create and net hal pins to get
values from hal.

I see what you mean now. The two paths to the same action are not well

S100 then starts the motor turning. S0 stops it but the M3 and S0 are still

An M5 then replaces the M3 with the M5.

OK, you can't see this in Touchy as the MDI interface needs you to
press M3 to get an S to fill out.
But Gmoccapy is the same.

I somewhat understand writing a Python program that reads/writes HAL pins and
starting it with halcmd loadusr. Is it possible to start a Python program from
a terminal window and access HAL pins without using halcmd? If yes, what is the

Also, after analyzing the code a bit further, it seems gearchange also has an
error. The scale value (for gear 2, the "high" gear) is used to divide the
speed in. This means that gear 2 is a lower gear, not a higher gear as the
documentation indicates. I.e. gear 2 would be divided by the
Ahh, very interesting. For the time being I’ll work on my own component and
see what I find. Thanks Andy!

Thanks again Andy, you answered my next questions. One final question. I see
gearchange was rewritten but then the rewrite wasn’t put into the final

.comp is C with some headers to create HAL pins.
You should be able to just edit the gearchange.comp file (probably

Hi Andy,
I might take a look at modifying the component. I’m comfortable with C, so
