That is great documentation too!
It's very good to see documentation on some of the inner workings of linuxcnc - lowers the barrier for new developers.
(you actually make a habit of good documentation!)

have any idea how SPINDLE_CONSTANT works? I assume it means constant surface speed...

The linuxcnc forensics & reverse engineering department has determined it's a noop:

from git.linuxcnc.org/gitweb?p=linuxcnc.git;a...52410e7a786578#l1430

maybe Alex Joni can shed some light on this:

$ git blame src/emc/task/taskintf.cc
...
1d62729f (Alex Joni 2006-07-10 21:35:34 +0000 1421) int emcSpindleConstant()
1d62729f (Alex Joni 2006-07-10 21:35:34 +0000 1422) {
1d62729f (Alex Joni 2006-07-10 21:35:34 +0000 1423) return 0; // nothing to do
1d62729f (Alex Joni 2006-07-10 21:35:34 +0000 1424) }

hey John I looked at your tutorial..

couple things I noticed maybe you already know...
in 3b the python code...
This is not needed:

# language stuff I think
import gettext
LOCALEDIR = os.path.join(BASE, "share", "locale")
gettext.install("linuxcnc", localedir=LOCALEDIR, unicode=True)
gtk.glade.bindtextdomain("linuxcnc", LOCALEDIR)
gtk.glade.textdomain("linuxcnc")
TCLPATH = os.environ

Also when putting the new screen in /bin you don't need to remove the .py part.
DISPLAY=gui3.py
will work.
The reason I mention this is if someone is testing it is nice if the editor knows the file is python.

great work though! is your plan to add it to the official docs ?

I wasn't really sure what the heck that code did... but I do know when I was importing the support libraries from touchy it was needed for some reason.

I was just blindly following the leader in removing the .py....

I've not given any thoughts to adding the tutorials to the docs yet but that is a good idea once they are polished up. I think for now I'll add some links here and on the wiki.

I added links to the wiki and the documents page here.

Thanks
John

I just gotta tell someone... I've been making progress on writing a GUI from scratch. The latest hurdles have been testing for a postgui file and running it if found, jogging the axes around and getting the value from a slider to control my jog speed and presetting the slider to a default value on start up and enabling part of the screen based on conditions like is the estop out and power on.



I'll work on adding gui 6 to the custom gui tutorial. This will add a lot of information about building your own GUI.

I sent a message about this on the mail list.
This is great work John! I think a lot of people will find this useful and will break down another guru barrier.
Thanks for sharing.

Chris,

Thanks for the explanation on the mailing list. It is clearer to me now.
