Trying to Configure Dual Y Axis

Limit switches on all axis. Dont need it now but eventually.
Don't need to square gantry.
Both ca run at the same time.

Thanks

In that case, make a new config, choose XYZ, and ONLY add the Y motor outputs twice. The same thing you did already, just do not edit anything.
Save, start and test.
This only works with one home switch for Y axis, and can be used with shared switches.

FYI, you can not have a tandem axis with home switches shared for all axis, maybe there is a way of having one Y joint with X and the other Y joint with Z axis, but never tried it so not sure it will work. It should though.
And by shared i do not mean home/limit shared, i mean a single input for more that one home switch.

Making progress.  The program now loads without any errors.  That's the good news.
The X axis seems to work fine.  However the "page up, page down" buttons that normally move the Z axis show movement of the Y axis on the screen.  Don't have the motors hooked up yet.  The normal up down arrows that usually move the y axis don't show any movement on the screen but do exhibit a travel speed.  
Seems like there is a "net" problem connecting the correct signals to the correct "joints".  After starring at these files for hours I'm just not seeing it,  hopefully someone else might see it.
I know Tommylight suggested getting rid of the Y0, Y1 labels and going back to just "y".  haven't tried that yet but will if this doesn't work.  Didn't want to reverse the progress (?)  I've made so far.

Really appreciate the help.

This is 'normal' if it does happen when your machine is not homed. For a gantry machine you MUST home all axis before being able to jog correctly. Even immediate homing will work and will 'link' joint yo and y1.

Ohhh!

This wrong:  Joint 1 HOME_SEQUENCE=-2
Get rid of the 'Joint 1' part of the line.
You should have only : HOME_SEQUENCE=-2

Same for all joints

And also there a bunch of thing missing.
Follow the instruction here: linuxcnc.org/docs/html/config/ini-homing.html#_immediate_homing

 

Thanks for your reply. I just opened the software and homed all 3 axis in place.
What was the Z control still moved the y axis on the screen. Can't move Z axis
