Finished my build but have a few issues that maybe someone can assist. 🇬🇧

I built the Nema 17 Heavy Version that is 1500mm (X Axis) and 1000mm (Y Axis).
The motors are functioning and I was able to do some test runs however I have a few issues.

1. When I move gantry to the very front of the CNC one of my Y-Axis seems stops moving (it almost feels like its binding).  The motor is trying to turn but it just doesn't want to go.  I wasn't sure if it was maybe a bad print on the front left support.  Has anyone ran into this?  

2. I am also seeing the same problem when I am moving the X-Axis to the far right.  I get about 2/3 of the way and then it acts the same way.  Feels like there is some type of binding.  I did measure the distance of the lead screw to the C-Beam and it appears to be the same distance at each end.  So I am not sure what else I can test.  Anyone experience this as well?  

Everything works great in the back left half of the table.
I am going start taking things apart and testing different things - just wanted to know if anyone ran into this on their build or has troubleshooted this before.
