Assembly
Frame assembly
In this section we will be looking at the frame assembly.
NOTE: Even if you have assembled a RepRap Prusa before please read these instructions as our frame differers slightly from the standard Prusa.
Tools
30cm rule
M8 Spanner
Step 1 Frame triangles
Components
- 4x Frame Vertex with foot
- 2x Frame Vertex
- 2x Bar clamps
- 6x 370mm M8 Threaded rod
- 28x M8 Nuts Bag 1
- 28x M8 Washers Bag 2
Instructions
Divide the above components in to two even sets.
Take one of the lengths of threaded rod and slide a bar clamp to the middle. Place a washer and then a nut either side of the clamp.
Place a nut, washer and then a frame vertex with foot followed by a washer and the nut on to each end of the rod. Loosely tighten the nuts.
Attach two more lengths of threaded rod to each footed frame vertex, using a washer and nut either side as before.
Attach a non footed frame vertex to the connect up the triangle.
Repeat all the above instructions until you have two matching frame triangles.
Place each frame flat on you desk, using your ruler tighten the nuts until each side is 290mm (measure from plastic to plastic)
Step 2 Cross Bars
Components
- 4x Bar clamps
- 1x Y Motor bracket
- 2x 608zz Bearings
- 4x 294mm M8 Threaded rod
- 14x M8 Nuts Bag1
- 15x M8 Washers Bag2
- 4x M8 Mudguard Washers Bag 3
Instructions
Take the Y motor mount and attach a 294mm length of rod through the bottom hole, approximately half way along the rod. Fix in place with a M8 washer and M8 nut either side.
Take a Bar clamp and attach in to a 294mm length of rod, approximately a quarter of the way in from one end. Fix in place with a M8 washer and M8 nut either side. Then attach a M8 nut and M8 washer half way down the rod. Attach this rod through the top hole of the Y motor mount.
Add the following components, a M8 Mudguard washer, M8 washer, 608zz bearing, M8 washer, M8 Mudguard washer and then a nut.
Add a bar clamp to the rod attaching with a M8 washer and M8 nut either side.
On a new 294mm length of rod attach a 608zz bearing, followed by a M8 washer, M8 Mudguard washer and M8 nut either side. Attach the remaining two bar claps either side of this, attaching with M8 washers and M8 nuts either side.
