MACH3 Homing Y/A Slaved axis together

I have upgraded my breakout board with a USB MK6-V motion card. I'm having an issue that my dual driven gantry Y/A axis drives are not homing together like they were. I have them jogging and homing together as they did before. But after each makes their own home switch. They take turns on offsetting back. Which puts the gantry in a bend. I had this problem years ago but haven't figured what i did. I think the problem was fixed when I installed a 2010 screen set. Which I can still use.Is there a macro that may have gotten writen over? Also I noticed my homing all order has changed. Old order z/x/y. New order z/y/x. Not a big deal other than OCD.

Most likely, the chinese controller doesn't support slaved homing.

Yes it does appear so. After several days trying different settings and macro edits. The best= I've adjusted the debounce from 5 to 2. Even though this a mm setting and I run in inches. Their setting is 1-5 in the plug-in configuration. From seeing and DRO. 2-5 are in mm. If set to 1 it goes to 1". That shows a bad design from XHC. So to sum this up. Yes it does square the gantry. But puts a slight twist in alignment while doing so. In my case that little is ok with my machine. This $300 chinese motion card is not as good as my $30 chinese DDMMV2.1 Parallel board was for me.
