2 steppers on one axis 5i25 - 7i76

I wholeheartedly agree with your suggestions on the naming conventions. The cleaner you make it, the easier it is to slog through the 3000 edits you'll make before it's "perfect". I'm still about 1,864 edit away...

Note my comments were directed at CNCzombie's config not yours.

The homing is different in master so make sure you drill down to the right documents
linuxcnc.org/docs/devel/html/config/ini-homing.html
Immediate homing is covered.

Set the homing sequence for Joints 1 and 3 to -1 and you are done!
When you do get your home switches in place, all you need to do to square the gantry is change the HOME_OFFSET
Also I found if you have a shared home/limit switch you need to move the axis off the limit switch with an offset otherwise you will get a limit error as soon as homing is complete (becasue the switch is enabled)

Chis, if its OK, I'll send you an email via the forum and sort out the config sample from there. I think it would be good to sort out pncconf a bit better.

Sound good Rodw

I have some Proximity Switch NPN to use for home/limit switch. Do you guys have any tips on how to wire them up?

On Mesa boards, PNP are the preferred type -- but both me and Rodw have rigged ours with NPN. And by me and Rodw I mean, he did it and I copied him

It requires a pullup resistor. PCW's guidance on the thread below clarified it for me:
