want 9 axes; STEPGEN outputs only 8 channels? was created by niftyEnt
I'm trying to configure HAL as 9 axis, but STEPGEN only outputs 8 channels.
Where do I get the 9th channel from?

Download the source and change the MAX_CHAN 8 to 9 in stepgen.c then rebuild and run as a RIP.

There was a suggestion on the IRC to up it to 16 channels like the pid component.

JT,
I have begun the process of understanding git and cloning a repo for my modification. Lotsa reading...
please clarify : " run as a RIP"

Also...
If I set STEPGEN to 16 channels, what GUI offers control of the additional channels?
I am currently using vanilla AXIS as my GUI, and 9 channels is all I need at the moment, but who knows what the future holds...?
No GUI will have more than 9 axes, however the stepgens can be used by other things like tool changers etc.

RIP = Run In Place. When you download the git repository and build it in a directory off of your home directory then you Run In Place vs running the installed version. I've just finished upping the stepgen to 16 in master and will commit it. So if you use master it will be there.
So in a terminal do each line one at a time
Now your running master.

Okay JT,
Going thru the steps described above I got:
configure: error: libmodbus3 not found!
install with "sudo apt-get install libmodbus-dev" or disable with
"configure --without-libmodbus"
so I ran:
tom@shop:~/linuxcnc-dev/src$ sudo apt-get install libmodbus-dev
then
tom@shop:~/linuxcnc-dev/src$ ./configure
again. This resulted in:
checking whether the Boost::Python headers are available... no
configure: error: boost::python is required to build LinuxCNC
so I guess I need Boost::Python.
Attached is the entire session in my terminal window.
Suggestions?

run in terminal
sudo apt-get install -y libboost-python-dev
their may be other dependencies needed as you go , see if this is the only on , if there is a few I have a script that may help

thanx Basher,
That did the trick.
I can launch linuxCNC from Terminal with:
tom@shop:~/linuxcnc-dev$ linuxcnc
but the configurations offered are from the stock version at:
tom@shop:~/linuxcnc$
Any idea how I point the config screen to the config folder at tom@shop:~/linuxcnc-dev?
