Y-plate assembly

Items you need for this step:

1y plate left
1y plate right
14M5 nylon insert lock nut
2Y inner side plate
14V wheel assembly from previous step
14M5 low profile 60mm screw
 12 eccentric spacer 6mm
14 6mm aluminium spacer
28 precision shim

 

And items for the nut blocks:

Use M5x25mm screws for that – they screw straight into the M5-tapped nut blocks

Do this on the two places – and please notice the orientation of the plate: the nut blocks should be at the opposite side where there is an indentation where the leadscrew for the X axis will come, if you want to put the leadscrew under tension from the outside

Do this for both plates

Then, use 60mm screws, and a 6mm spacer, precision shim, a v wheel assembly, a 9mm spacer, another V wheel assembly another precision shim and another 6mm spacer to attach the wheels before attaching the inner plates:

And for the lower rows, use eccentric spacers instead of 6mm spacers:

And the inner plate and tighten:

Do this for both plates (mirrored), and also attach a motor with adapter to the left plate assembly (not to the right plate assembly!), with 40mm aluminium spacers and 50mm screws:
