Well, I’ve measured all the fundamental dimensions: conduits lenght and the diagonals were correct. Despite this the bars of the gantry weren’t perpendicular. The problem is in the z-rollers and z-roller locks of Y axis. I dissassembled the gantry and I saw that when I tighten the lock in the z-roller the axis of the Y conduit swivel so it is no longer at 90 degrees with X axis. This leads to a difference of more than one inch between the two edges of the Y conduit, measured on X axis. The z-rollers of X axis are perfect indeed. I don’t know why…
Now I’m furiously grinding the indicted pieces, tomorrow I’ll say to you ๐Ÿ™‚ . I hope not having to reprint the z-rollers (12 hours of time lost).
