Today I decided I would find out for good what was it that was holding me up. I decided to try everything so I changed the X and Y connectors and my Y started shifting (Still my X physically), so I knew it was not the driver, I decided to try to realign every single belt, pulley nut and bolt. Still did not do it. So I decided to change the motor, as I have spare ones, and as I was doing so I found the cause: "a broken motor mount" the motor shaft what quite misaligned in relation to the X rod it was connected to and the excessive momentum was causing it to bind! I have steel mounts the old ones are aluminum, put the steel mount carefully aligned it and tension the belts, and BINGO! Everything is back to normal!
Thanks a lot for the help guys! I really appreciate it!
