X-carriage assembly (requires update)

Attach 6 V wheel assemblies to the Z plate with 30mm screws – and at one side of the plate, use 6mm spacers with a precision shim, whereas at the other side, use eccentric spacers with a precision shim:

Then, attach the Z axis nut block:

Use 25mm or 30mm screws to attach the nut block – and position 3mm spacers between the nut block and the Z plate, as highlighted with the red arrow. Use M5 lock nuts to secure the screws and nut block.

Now the x carriage will be built in a similar way as the Y side plates have been built, with 60mm screws, but notice that the high spacers are now on the top:

At the side of 4 wheels: first put a 6mm spacer + wheel + 9mm spacer + wheel + 9mm spacer

At the side of  3wheels: eccentric spacer + wheel + 9mm spacer + 3mm spacer + eccentric spacer:

And put the other x carriage plate on top and use M5 nylon lock nuts to close.

Now is also a good moment to attach the Z axis limit switch as it’s easier to reach now:

And attach the Z plate to the X front plate with 20mm screws:

And add the Z axis extrusion:

And the Z axis motor and leadscrew:

With 40mm spacers and 50mm screws:
