W axis with gantry kins hal/ini configuration

Thanks for that, I'll have a go with JA9 tomorrow and report back. I think a working gentrivkins is preferable to gantrykins, ignoring soft limits scares the hell out of me!

Could you also please tell me what KINSTYPE=BOTH does? I can't seem to find anything out about it.

The code is basically identical for gantrykins and gentrivkins.
I don't know the reason for both or the naming history.

In joints_axes9, gentrivkins has a (new) module parameter
kinstype for testing. It makes it possible to test a simple
kinematics module as if it were a more complex
(non-identiry) kinematics type.

I used it in the example to illustrate switching between
joint and teleop mode so that you can see the pos-cmds for
both modes in the included halshow gui.

Some guis (axis for example) suppress joint/world switching
for identity kins. In the g.tgz example, remove the text
'kinstype=BOTH' to see the gui behavior for kinematics that
are strictly identity.

I've built JA9, configured with gentrivkins and everything is working perfectly! Gantry auto-squaring, obeyed soft limits and automatic teleop are exactly what I was after, thanks Todd, Dewey and Andy for your help with this. I expect the problem remains with gantrykins and non JA builds but I much prefer this setup.

Would you mind sharing your config? I need to set up a gantry with auto-squaring myself.

Does the author of the Joints branch have any sample configs?

LCNC is like the punishment of Tantalus.

I can post my config files later tonight for you
