A notice about these instructions!

Since 1st April 2013, the RepRapPro Mendel has been superseded by the RepRapPro Tricolour and Mono Mendel.
If you are building the new machine, use the official, and most up to date, instructions on the RepRapPro wiki here

Goal

By the end of this stage, your machine should look like this:

Tools

You will need the following tools

M8 (13mm) spanner
Adjustable spanner
M3 Allen key
M3 set screw Allen key
M3 spanner/nut runner
Long-nosed pliers
Side cutters

Step 1: Y motor and mount


Item	Quantity
Printed Y motor mount	1
Printed Y motor lid	1
Nema 17 motor	1
M3 x 35mm screws	3
M3 x 10mm set screw	1
M3 nut	1
M3 x 10mm set screw	1
M3 x 8mm screws	2
M3 washers	3

Use the two short screws to attach the motor to the half of its mount with the projections.

Screw the set screw into the toothed-belt pulley. Take care not to cross the threads - the plastic is not hard. Screw it in far enough to project into the hole down the middle, then back it off so it is no longer projecting. Blow any displaced pieces of plastic from the central hole.

Put the pulley on the motor shaft with its hub outermost, as shown. Align the set screw with the flat on the shaft, and tighten it. Do not over tighten it - the pulley has an internal embedded nut, and over tightening will cause this to fracture the pulley.

Use the remaining screws, washers and nut to attach the other half of the mount cage. There is a recess for the nut, which should be a tight fit. Take care when tightening to pull the nut into its recess that the hexagon of the nut is aligned with the hexagonal recess.
