Hexeract

Open-source Core-XY motion platform mainly for "large" print volume desktop 3D printer hexeract__Motion_ _Extrusion Platform v81

Introduction

The Hexeract is an open-source Core-XY motion platform with a rigid main chassis using 3030 aluminum extrusions and moving components constructed by 1515 aluminum extrusions.

The design is a motion platform, components like; motherboard, LED lights, HEPA filters, and more are for the individual builder to determine. Also, the "Hexeract calculator" will output the length of components to accommodate various size requirements.

DISCLAIMER: Not for the faint of heart

The cost of building will probably be higher than you think
The allowable tolerance of the printed parts are tight

The rate of development and updates will be uncertain until the first quarter of 2022 (refer to the announcement in the Discord server)

This project is in development
The current "Bill of Materials" and "Assembly Guide" are barebones
The "Calculator" is incomplete

Community: Discord

The announcement will explain a lot of the incompleteness of this project
Designer will be there on the weekends answering questions

Recomended Print Settings for 3D Printed Parts

Filament Material: PETG, ABS, ASA
Layer Hight: 0.2mm
Extrusion Width: 0.4mm
Infill Percentage: 20%
Infill Pattern: "Tri-Haxagon"[Cura] / "Star"[PrusaSlicer]

Hexeract Calculator (In Working Progress)

If one wants to have a different print volume

Recommended X-axis "Print Volume" : 250mm ≤ (x-axis "Print Volume") ≤ 450mm
Significant modification will be necessary to the Z-axis if one wants to go with a larger print volume than standard.

How to use the calculator (In Working Progress):

Assembly Guide

Insert the 45mm hex head M5 screw FIRST in the "P_Belt_Tensioner" during assembly.
All the Brackets that attach to the 3030 aluminum extrusions will use 15mm button head M6 screws to attach
All the Brackets that attach to the 1515 aluminum extrusions will use 8mm socket head M3 screws to attach
A rubber, wooden, or plastic mallet/hammer could be necessary to tap in the press-fit components

Recommended Tools: Quality will matter to an extent

2.5mm ball-end hex screwdriver
4 hex Allen wrench with ball-end
5 and 6 mm hex Allen wrench
Nipper
Rubber mallet
Ferrule Crimpers
Engineer PA-09
Engineer PA-05
PTFE based synthetic grease
