Introduction

Prusa 3D printer Hephestos is a free project 'designed and developed by the Department of Innovation and Robotics bq'. Hephestos is based on the Prusa i3 and adds several improvements learned from other printers as PowerCode users of the RepRap community, modifications to these parts and designs own department.

This project has sought to offer a robust printer design that solves many of the shortcomings of earlier designs such as the subjection of the limit switches and cable routing. We have placed particular emphasis on providing good documentation to facilitate and more comfortable to the user installation and commissioning of the printer.

The complete kit can be purchased from July 7, 2014 on the website http://store.bqreaders.com/es/diy/ 499 Euros with VAT in EU (European Union) Free shipping expenses.

Modified

X Axis carriage

The original carriage will have made the following changes:

-Attach to rewind Igus chain stitch at the top (above the bearings).

-Addition of a small cap to ensure contact with the limit of X axis (on the side, next to the linear bearing carriage below)

End of the X Axis motor

To provide robustness to the screw to adjust the height in Z.

-The base is elongated and has reduced the looseness of the nut to prevent the screw from moving.

-Has shifted the screw hole out to get a better accuracy in mechanical Endstop activation.

RAMPS support

They have added three hooks. Each hook allows through a bridle, hold and collect all the cables connected to the RAMPS. By guiding the cables through the side and into the plate at the top left corner promotes cooling of drivers having no cables above the sinks.
