I am putting my J type (25.4mm) machine together and have noticed that my X-Axis gantry rail sits 1-2mm above its corresponding rollers, not flat down on them (Y-Axis rail sits down flat on its rollers). This means it can rock with the middle assembly and Y-Axis rail as the pivot point. It’s not a lot but it is there. I checked the rail and it is straight.
Is there a height adjustment I’ve missed? All I can think of is that the rail spacers are too thick which lifts the Y-Axis rail slightly (Y rail is on top). The Y rail runs through the top of the Middle Assembly which lifts the X-Axis rail slightly above its rollers.
Has anyone else noticed this? Am I getting too fussy?!
Thanks in advance.
