Concepts

This page outlines our concepts and naming conventions, which we'll reference in the build instructions later.

Printed part codes

Our parts have printed codes to aid assembly.

1. A part code identifies

   1. If the part belongs on the left (‘L’) or right (‘R’) side of the printer.

   2. The version of the part.

Flange Stacks

Flange stacks (along with 5x30mm dowel pins) are used to create smooth idlers.

Quality idlers, smooth and toothed, are key for your printer's performance. We use flange stacks throughout assembly.

Single flange stacks use

• three (3) shims and two (2) bearings.

Double stacks uses

• five (5) shims and four (4) bearings.

Types of Idlers

Smooth Idlers

Smooth idlers are the most common idler that we will use; they turn the belt around its smooth side.

A single flange stack has one (1) smooth idler; a double flange stack has two (2).

Toothed Idlers

Toothed idlers are used on the X joints only. These are used when the belt turns towards its toothed side.
