  1. Attach 2 x ACME-Nut-Blocks to one of the Y-Plates using 4 x M5-Low-Profile-25mm bolts & 4 x M5-Nyloc-Nuts. On each bolt, in-between the ACME-Nut-Block and Y-Plate, there should be an Aluminium-Spacer-3mm and a Precision-Shim. Only loosely tighten these bolts so the ACME-Nut-Blocks can still move side to side. Thread a Y-ACME-Lead-Screw through both ACME-Nut-Blocks. Tighten the bolts holding one of the ACME-Nut-Blocks, making sure it is square to the Y-Plate.

    • Thread a Y-ACME-Lead-Screw through both ACME-Nut-Blocks. Tighten the bolts holding one of the ACME-Nut-Blocks, making sure it is square to the Y-Plate.

    • To remove any backlash, pinch the loose ACME-Nut-Block towards the previous one, and tighten the bolts holding it. Leave the Y-ACME-Lead-Screw threaded through the ACME-Nut-Blocks.

  2. First attach the bottom right wheel set; insert a M5-Low-Profile-60mm bolt through the Y-Plate-Assembly from the back. On to this bolt, add an Eccentric-Spacer-6mm, Precision-Shim, Solid-V-Wheel-Xtreme-Assembly, Aluminium Spacer-9mm, Solid-V-Wheel-Xtreme-Assembly, Precision Shim, and a Eccentric-Spacer-6mm in this order. Next, add a Y-Plate-Inner onto the top of this assemblage, and then slightly thread on a M5-Nyloc-Nut. The rounded portion of the Eccentric-Spacer-6mm should be inserted into the hole on either the Y-Plate-Assembly or Y-Plate-Inner (depending on which side it is on).

    • Repeat for the other wheel set on the bottom row corner.

    • Repeat for the 2 wheel sets on the top row, however for these sets use Aluminium-Spacer-6mms instead of Eccentric-Spacer-6mms.

    • Once all of the wheels are attached the M5-Nyloc-Nuts can be tightened down. Ensure that the Solid-V-Xtreme-Wheels can still rotate freely. On the hexagonal portion of the Eccentric-Spacer-6mm, there will be one face that is marked with ‘6mm’.

    • Using a spanner, adjust each Eccentric-Spacer-6mm so that this face is facing downwards. Doing this maximizes the gap between the top and bottom row of wheels.

  3. Run any piece of C-Beam extrusion in-between the two rows of wheels. Initially, there may be a small amount of play between the C-Beam and wheels. Turn the assembly upside down so the C-Beam is sitting on the row of wheels with the Aluminium-Spacer-6mms.

    • Starting with one pair of wheels, adjust both Eccentric-Spacer-6mms down onto the C-Beam Extrusion until there is a small amount of friction between both wheels and the C-Beam Extrusion.

    • When adjusting the pair of Eccentric-Spacer-6mms ideally they should be adjusted identically. However, sometimes one will need to be adjusted slightly more than the other to get both wheels engaged with the C-Beam extrusion.

    • Repeat for the other pair of wheels with eccentric spacers.

    • Slide the C-Beam extrusion back and forth through the wheels. This should require a small amount of force, and all wheels should spin as it rolls. Also check there is no wobbling of the extrusion. Once happy, double check the tightness of the M5-Nyloc Nuts.

  4. Repeat the this section for other Y-Plate. As seen it should be a mirror image of the previous assembly. A NEMA23-Stepper-Motor needs to be attached to the second Y-Plate Assembly. See pictures 2 & 3. Slide the 1/4” side (the side with the smallest hole) of the Flexible-Coupler onto the shaft of the NEMA23-Stepper-Motor. Don’t tighten it down at this point.

    • Attach the NEMA23-Stepper-Motor to the threaded holes on the Y-Plate using 4 x M5-Low-Profile-50mm bolts and 4 x Aluminium-Spacer-40mm’s.

    • Orient the NEMA23-Stepper-Motor so that the wire is towards the back of the Y-Plate (the side closet to the small rectangle opening).

    • The Y-Plate Assembly with the NEMA23-Stepper-Motor will be known going forward as the Y-Plate-Left Assembly.

    • The other Y-Plate Assembly (Without the NEMA23-Stepper-Motor) will be known going forward as the Y-Plate-Right Assembly.

I'd have loved to get a free cheap thin 6mm spanner it the kit I received. Everything had to be stopped till I got a specific spanner from the shop.

I agree, a cheap 6mm spanner would have been great. I think it is good that not all tools are provided, like with some kits, since most often you already have the required tools, and including them is a waste of resources. A 6mm spanner is probably quite uncommon to have, and an adjustable spanner does not fit. Although not optimal, I was able to use pliers.

To corret myself, the 6mm nuts require a 8mm spanner.

These guides should have a list of required tools and sizes. Is that posted somewhere and I’m missing it?

I’d love it if this forum had delete & edit buttons that worked! Could get a bit useless, quickly, otherwise..
