Wholly agreed as I still have to make a minor adjustment to even out the X-Axis but it hasn't affected my three test prints so far. I didn't replace the two long Y-Axis belts yet, only the short rear Y-Axis belt and even by doing that it's easy to misalign the axes. It really doesn't need to be perfect but every little bit helps I'd say. In my thread (http://3dprintboard.com/showthread.p...lt-Replacement) I went through most of the details for replacing the short rear Y-Axis belt but I'm interested to know how you got the two Y-Axis belts out of their holders.
Getting the belts out was not a problem! The machine helped on that one! Looking back I think a pair of needle-nose pliers and slide the end of the belt out going toward the middle of the machine or pull toward you. I think you could try to take the spring tensioner off first and it might be a bit easier.
To re-align I made sure the two belts were exactly the same length, down to the tooth. I then started one end with a specific number of teeth showing beyond the end of the holder then wrapped the belt around got it tight and put the other end in the holder. On the second one I started with the same number of teeth exposed for one end and put the other end in the holder with again the same number of teeth exposed after the holder. I don't know if that got it aligned but it meant the tension should be the same on both sides.
Finally I loosened the set screws on all of the four "gears", one in each corner so they spun freely then moved the carriage to one end up to the stops and tried to make both side even then tightened the gears back up. Seems to do ok but I am sure my process can be improved. I did this with the whole top off and the gantry unit on the table bolted into the top frame.
