Put the M3 locknut [HD-NT0001] into the 5.5 mm nut driver jig, the nylon ring on the locknut should be on the bottom.
Insert the nut driver into the longer hold of the Y-Rod Mount. Make sure to firmly press the nut driver inside the hole.
Then, use a M3x12 SHCS [HD-BT0039] and an M3 washer [HD-WA0038] to pull the nyloc into the hexagon shaped hole in the printed Y idler [PP-GP0263].
Inspect the locknut to make sure it is seated into the nut trap correctly.
Back the screw out until it is flush with the printed part, and then repeat this process for the other side of the printed part.
Place 2x bearings [HD-MS0282] inside the Y idler jig then set 2x M8 washers [HD-WA0006] next to the bearings.
Put a M8x40 FHCS [HD-BT0117] through the countersunk hole in the printed Y idler part [PP-GP0264]
Place an M8 washer [HD-WA0006] and an M8 locknut [HD-NT0002] on the end of the M8x40 FHCS. Use a 5mm driver and a 13mm wrench to turn the nut onto the bolt.
Fasten bolt until nut is tight against the washer and bearing can freely spin, but do not tighten it.
Attach the belt clamp [PP-GP0277] to the belt mount [PP-GP0278] using 2x M3x12 SHCS [HD-BT0039] with M3 washers [HD-WA0038] with the wider side towards the base of the mount. Leave the screws loose as they will be tightened at the Final Mechanical Assembly.
Make sure to install the belt clip with the treads on the inside to grip the belt
Using 2x M3x10 BHCS [HD-BT0137] and 2x M3 washers [HD-WA0038] fasten 1x flexy bed corner [PP-GP0396] to the bed plate [PP-FP0171].
Then repeat step for the other three bed corners.
These may be left loose for the time being; they will be tightened in position with the bed heater at Calibration.
Use the printed bed plate jig to install the bushing holders and belt clamp. With the ground side closest to you, place the single bushing holder [PP-GP0134] on the left side. The bump stops should fit into the indents of the jig.
Then place the double bushing holder [PP-GP0133] on the right side with the cutouts facing the center of the jig.
Place the belt clamp assembly in the center with the flat edge and screws to the left.
Set the bed mount plate on top with the ground screw in the bottom left corner.
Secure the left half of the single bushing holder with 2x M3x6 FHCS [HD-BT0128].
Then secure the left side of the single bushing holder, belt clamp, and the double bushing holder using 9x M3x8 bolts [HD-BT0137] with M3 washers [HD-WA0038].
Tighten the right side of the single bearing holder and the belt clamp, but leave the other screw loose.
Use the 8 mm reamer to gently ream the Y idler. Take care to keep the tool straight and to not remove too much material which would result in a loose fitting rod.
Take note of the orientation of the bushing holders shown in the picture.
Slide 2x harden steel rods [HD-RD0078] into the double and single bearing holders.
Then take the Y idler and slide it on the end of the rods making sure its closest to the ground screw on the bed plate. If the rods do not seat, it might be a sign that the reamer tool needs to be used to clean up the hole in the printed part.
Now take the Y motor mount [PP-GP0263] and slide it on the other end of the rods.
Using 2x M3x6 FHCS [HD-BT0128] attach the Mini 2 bed harness [AS-CB0071] to the bed plate. Use the end of the cable chain that has the wire connectors.
Place 1x M3 internal tooth lock washer [HD-WA0035] and the brown and white grounding wires around the grounding screw and tighten with 1x M3 locknut [HD-NT0001].
Align the cable chain mount with the two holes in the bottom plate [PP-MP0258] and secure using two M3x6 FHCS [HD-BT0128].
Flip the bed plate assembly so the bed plate is resting on the table, then carefully flip the bottom frame plate and bed plate into position as shown.
Using 4x M3x8 BHCS [HD-BT0137] with M3 washers [HD-WA0038] secure the Y axis idler to the bottom frame plate.
Make sure the front of the Idler printed part remains flush with the idler mount of the Frame.
Secure the Y motor mount to the motor mount flange of the bottom plate using 4x M3x8 BHCS [HD-BT0137] with M3 washers [HD-WA0038].
Make sure the back of the Y motor mount remains flush with the motor mount flange of the frame.
Flip the assembly over so the bed plate is on top, and tighten the two loose screw holding the single bearing holder.
Then slide the bed plate all the way towards the Y motor mount until it stops. Then tighten one of the screws holding the double bearing holder.
Now slide the bed plate the other way until it stops so that its covering the Y idler. Then tighten the screw that diagonal from the screw that was previously tightened.
Slide the bed plate assembly to the middle of the rods and tighten the other two screws.
