The final step is to put the plastruder on the Z board and to attach the [not] Ethernet wire between the plastruder and the motherboard.
I also clipped the USB cable on the power from the PSU to the Mother Board as a strain relief.

Next up, install the software; run the tests and then if nothing burns up make a first print.

The only challenge here is figuring out witch motor should go to each board.

I found a nice wise grip to crimp the cables with

Next step, the Plastruder.

Quick and simple.
The only trick here is to measure the hight of the nuts (that moves the Z table) before putting it in. That was a loot easier (and quicker) than trying to guesstimate where they should be.

The wiki says: *TIP* If the rods are too short they will move back and forth causing loss of resolution and additional noise. If this is the case for you, just insert something between the end cap and the rod to help compress it.
Well I put one of the M3 nuts in each of the two caps to press the rods into position.

The parts needed for this laid out

Assembled and done.

This part was installing the drive rods and belt drive system for the Z-stage.

Even though there are teeth on the idler wheels, the teeth of the drive belt should be facing outwards (from the wheel).

The assembled Z-Stage.

Very simple stage to assemble. Probably took a lot less time than the wiki suggested.
Now it is simple to see what the completed cupcake will look like.

Tips for others:

• I thought I was smart when I got a shorter M5 for the idler pulley (I had a M5x40 that I tried to use instead of cutting the M5x45) screw (instead of cutting it down) – however it was not threaded as long as the longer screw so it didn’t fit under the X cap. If you think of using a shorter screw, verify that it will fit under the X cap.

The only problem I ran into (apart for the screw) was that when I made sure there was 1 mm clearance between the drive pulley and the motor the timing belt was not level with neither the Y-stage nor the idler pulley. I moved the drive pulley several mm’s up until it was level with the rest.
That was not a major problem as it was easy to reposition it, but it was time consuming to get the drive pulley to be 1 mm above the motor.

The big screw is not the right one, the small image is with the right screw (before it was cut down to size)

And the completed assembly:

This part was very simple and straight forward.

The only two problems I ran into while making the Y-stage was

• That I did not know what “Flanged bearings” were – and it took me a while to find the <a href="part lists in the subversion archive. Once I had that it was simple to find a data sheet with a drawing on it.
• [not MakerBot related] The lid for the superglue bottle had been glued to the plastic below. Had to find a Tongue-and-groove pliers to get it unstuck

Tips for other builders:

• Try to insert the magnets from both sides before finding a small file to make the holes larger
• If you are unsure what the part you are looking for should look like, consult the part list and the try to find a drawing of it – if you live in a country that isn’t native English speaking there is little point trying to ask others; unless they have made a MakerBot or similar before.
• When adding the acrylic build surface to the wood start with the two screws that are diagonally to each other (if you would start with one side there is a rather large chance that the last screws won’t line up correctly) [see construction picture 3]
• When putting in the last magnets, using a plastic plier (or some other non magnetic item) is easier than using a hex key 😉
