When assembling the the X CARRIAGE and BED SUPPORT CARRIAGE, the BEARING CLAMPs are open on one side so they can slide over the bolt/washer, and closed on the other side. Does it matter which way these sides are oriented? I ask because the BEARING CLAMP pieces are not 100% symmetrical – the BEARING CLAMPs will shift a few mm from side to side if you turn them around 180 degrees on their bolt/washer, which slightly changes clearances elsewhere as you build…
