Just wanted to say thank you to everyone that replied to my question about
learning gcode. I really appreciate all the help and info that everyone passed
along.

Hello,
Unless I am very wrong this patent is a non-flyer.
The old G-E systems had a discriminator that measured the difference
in phase between the command pulse train and the feed-back pulse
train, and the output of the discriminator was the input to the drive
amplifier.
So how on earth you can in

Is there a good online reference or set of instructional materials for learning
about gcode and programming that I could check out in addition to the gcode
info on the emc page? I'm really wanting to learn how to get the most from my
machine and my programs and my knowledge is limited.

The 2.4 docs are online on the Documents page. If you installed 2.4 from
a deb then the docs are on your computer all ready.

2.3.5 is the "Safe" released version, but as you have found it lacks
some features.
It does seem that you have a knack for needing unusual features.

Hello...
Now I'm totaly lost. What version to use? Is there "safe" version?
The story..
I hit (expensive) bug in 2.5.0~pre check [Emc-users] Tool Crash when STOP
So I go back to 2.3.5 and recompile with latest stepgen.c
Now another thing doesn't work see [Emc-users] Unhome on ESTOP
Someone poi
Use 2.4.0~pre, there are all bugfixed there now, and it has unhome pins
in halui.
Only copy stepgen.c from master to use custom steps.
