Gantry hal example

AFAIK
Pncconf nor stepconf have not been modified to work with JA configs.

I don't plan to until it's merged to master.

Maybe you can use pncconf then convert the config with Andy's script. - I doubt there will be great success unfortunately.

What version of linuxcnc does this not work?
You should be picking X and X2 for master and slave for instance.
It certainly could be broken I haven't tested it in a long while.

No it seems to be working on the latest JA14 build, the only issue I have now is how to configure the limits on the primary and master so they work independently while homing. I think it is supposed to be much simpler than using the Gantry component but I cannot find any samples of how to make it work.

joints_axes14 update for wrongly placed HOME_ items:

git.linuxcnc.org/gitweb?p=linuxcnc.git;a...3a498c7a9be9bcc9372e

Note: joints_axesNN branches have made minimal updates to
stepconf/pncconf to continue their support for identity
kinematics only.

Support for non-identity kinematics and advanced settings for
identity kinematics that 1) allow omission of axis coordinate
letters and 2) support multiple joints for a single axis
coordinate (gantry for example) are not currently available.

Nonetheless, pncconf/stepconf generated configurations are
often a suitable starting point for editing hal and ini files
to handle the less-frequently used configurations.

I have spent hours trying to figure out how to independently home my two tandem axis steppers in JA14. I have not figured out how to do it and I read the JA docs several times over. All of the examples use the Gantry component which is supposed to be unnecessary in JA. Can someone help me by either giving me the syntax and/or pointing me to an example done in JA of homing Y and Y2 independently?

buildbot.linuxcnc.org/doc/scratch/v2.8.0....html#_home_sequence

Multiple joints don't home independent of each other, the both home at the same time or your gantry would rack. When the first side completes the homing sequence of search and latch it waits for the second joint to complete the search and latch operation then they both move to the home offset together. Home offset is where you can make minor corrections to the home switch locations to obtain a square gantry.
