Working on the Y motor mounts. They look right, but there's a size issue...
I changed the X rail supports. Old way put holes at 25mm height. didn't work for skinnier pieces.
New way puts holes at half height.
Fixed the Y motor mounts, I think. They were still sized wrong when I made them, but perhaps that's the machine that made them? I hope note....

I did some small cleanups too.
I added code to auto do the size of the hole in the middle of the motor mount on the X gantry and Y motor mount.
Changed table so skinnier X Rail supports
would be at correct height.
I changed the X Gantry height to refer to the Y gantry height.
Less calculations is more better.

I need to change the attachment spots for the Y Rail.
I had the Y gantry mounting holes completely wrong on the X gantry.
Also, the X gantry was too short.
It should be fixed now.
Just committing to get rid of all the stupid extra files
