Build Instructions

The build instructions below are divided into two parts, namely pre-assembly and final assembly. In the pre-assembly some of the sub-assmeblies or parts are either prepared or assembled together to ease the final assembly. The number in the (#) paranthesis denotes the quantity of the part required.

Hardware

Button Head Cap Screw (BHCS)	Socket Head Cap Screw (SHCS)	DIN 433 Washer	Teethed Idler Pulley
BHCS have a button shaped head with a hex slot and require an allen wrench	SHCS have a cylindrical head with a hex slot and require an allen wrench	DIN 433 shims are washers with a consistent thickness made by cutting and so can be used as spacers between idler pulleys	Teethed idler pulley has free rolling bearings and the toothed side of a timing belt moves on it

Smooth Idler Pulley	Drive Pulley	Heatset Insert	Set Screw
Smooth idler pulley has free rolling bearings with the smooth side of the backside of a timing belt moves on a smooth idler pulley	Drive pulley sits on a motor shaft and is always teethed. Comes with two set screws that need a allen wrench to tighten the pulley onto the shaft	Heatset inserts have ridges on the outside and a female thread on the inside. They are pressed into printed parts using a soldering iron	Set screws are headless screws with external threads and a hex key on one side. Found on drive pulleys and in the L brackets to join two aluminium profiles

L bracket	Angle Connector	Allen Wrench	Flat Head Screwdriver

| L bracket is an L shaped connector with 2 set screws, used to connect two T-nut profiles at a right angle. The L bracket sits within the T-slots of a profile and so is concealed | Angle connector are aluminium connectors that connect profiles on the plane. Each angle connector requires 2 SHCSs and 2 hammer nuts | Allen wrench is a tool with a hex head to tighten srews with a hex slot | Flat head screwdriver is a tool to tighten flat head screws which are found on the electronic wire terminals of the controller board | Cross head screwdriver is a tool to tighten cross head screws and found on the controller board with electronic wire terminals | LINK |
