Making some axes independent of the motion controller

Thanks. I didn't realizes that changes would be made that wouldn't be backwards compatible... I've gotten the homing sequencing orders figured out.

Then I spent an hour trying to figure out why some axes weren't working, and it turned out I had to change the control type and connect the amp-enable-out pin to the right place. I guess it says something that I was able to figure it out without having to beg people on this forum to help me!

I'm going to call it a day and start testing my existing g-code with the new joint system tomorrow.

wouldn't be backwards compatible

A version change from 2.7.x (the current release)
to a new major release like 2.8.x (currently the
master branch identified as a PRE-release version
(2.8~pre1) in:

github.com/LinuxCNC/linuxcnc/blob/master/VERSION

may be expected to break configs and/or require changes
to ini and hal files.

Experimental branches are almost always based on the master
branch -- so it is recommended to study:
linuxcnc.org/docs/master/html/getting-st...dating-linuxcnc.html

For instance:
Ref: linuxcnc.org/docs/master/html/getting-st...html#_home_sequences

all postgui is to be selfmade changed to the new system
so stay as long as you can

Here's a description of a subtle change I noticed:

When trying to turn off homing on an axis, I first just commented out the HOME_SEQUENCE line like your instructions suggest. However when I started up LinuxCNC the "Home All" button had changed to "Home Joint", and I had to home the other 7 joints individually. I scrolled down and implemented the instructions under 3.13 Immediate Homing . Then I get the "Home All" button back. I'm not sure if that behavior was intended or not, but probably the documentation should reflect this.

@dgarret .... read these post in these days .... really baased on these 
#124678    your explanation I understand my problem in extrajoint usages ...... some time my application must go in emergency mode .... can be during emergency encoder on extrajoint move for 1/2 revolution .... when return in normal mode limit3 can't drive extrajoint correctly because "offset" accumulated during emergency .... whitch pin can use to reset these "offset" ??   

real
thanks
