I have noticed that the forward linear bearings on the y carriage end up running into the y axis corners about 20 mm before the extruder reaches the end of the y axis.
How do you get the full 200 mm out of the y axis? Do you need a special y carriage?
That depends on your frame.
Mine has slotted holes for the y-carrier, therefor I can adjust the table and fix it with the M8 screws at the vertical frame strut.
