RE: [CAD_CAM_EDM_DRO] study, study, study

Weyland,

A newbie is the perfect person to write documentation. Once you are familiar
with the program you have a tendency to take too much for granted. If you
look at www.linuxcnc.org you will see the beginnings of a manual. Jump in
and write some more of it as you are starting to understand it. I wrote a
scripted install for the previous version way back when I was getting
started. Just made sense. I was doing the manual install and compile enough
as I was screwing things up that I figured I may as well make it semi
automated. An experienced EMC user would be at a loss as they are likely to
have not done a full install in a long time. Same thing with documentation.
Just start collecting your questions and the answers onto a file and polish
up the wording.

There are a number of motion modules. You specify which one to use in the
[EMCMOT] section of the ini file as EMCMOT = .

steppermod.o : the original stepper module. Problems with pulse pacing.
Works great for step and direction servos and steppers with a pulse buffer
like the G210 Gecko drives.

freqmod.o : An updated stepper module. Much improved pulse spacing (still
not as good as a dedicated external generator //Hint, hint Jon//). Pretty
heavy overhead on the computer which tends to limit maximum step rate.

smdromod.o : a modified version of freqmod.o that uses actual encoder
feedback through a Mauch/Kulaga DRO card for closed loop stepper operation.

stgmod.o : A true servo motion module for the Servo to GO card

stg8mod.o : Another true servo motion module for the Servo to GO card. I
think this one enables all 8 axis for robotic purposes.

emcmotsim : A simulator version

I think there is actually another servo version for the version 2 STG card.
