Y axis has two joints and they move in opposite directions

I thank you for all your comments. I am attaching my .ini and .hal files after I worked on them yesterday Yesterday was the first I had been able to work on this.
This is a machine that had worked until I recently found out about 2.8 and downloaded it and installed it. So I was puzzled why the wiring would have gone bad. I figured I had made mistakes when I did the hand edits on the files after generating them with stepconf.

So yesterday I tried different arrangements of the inversion of the y0 and y1 joints and with both not inverted they both go in the same direction. Now all I have to do is to get the Y axis so that it goes in the right direction when it tries home.
Thanks again.

Change the sign of home_search_vel. I think thats the correct one.

Homing Docs

Thank you very much for that. I had printed out the homing part of the linuxcnc documentation but had not looked through it yet but I tried the change you suggested
and all is well.

[justify]Hello I am new here I am also facing a similar problem .I am setup my stepconf for tandem y axis (Dual y axis) when i am jogging the machine in direction it works fine but when i jog it in - direction both y axis motors moves in opposite direction and throws my gantry out of square
solution i have tried[/justify]

1.  Swapping wires on driver
2.  inverting Dir pin
3.  Putting negative scaling for one of the y motor
4. changing the direction in my Driver

[justify]Note : i have tried above mentioned solution one at a time not all at once Still No success
I have attached my ini and hal file help me out
  

This is the driver i am using

Is there a missing word in this sentence? 

If you are saying that jogging one way works, and jogging the other doesn't, then that would seem to suggest that one motor moves in the same direction regardless of the DIR pin, and you probably need to check that. (You can check DIR with a multimeter) 

Some servos have a setting to reverse the default motion direction. This may need to be set on one drive.
