Overview

The group has purchased and assembled a Prusa Mendel 3D printer. This page gives some instructions on its use

Mechanicals and Electronics

The Prusa Mendel is a type of RepRap printer http://www.reprap.org/wiki/Main_Page . It uses threaded rods for the frame, with a total of 5 stepper motors... 1 for X, Y, and the extruder, and 2 for the Z axis. Our version uses a RAMPS v1.4 board, with a SD card reader and LED display panel for headless printing.

Software

There are 3 things you need to acquire in order to use the printer: slicing software which generates the GCODE, printer controller software that measures temperatures and sends code to the RAMPS board, and custom configuration software we have created specifically for this project.

slic3r

You can acquire slic3r here: http://slic3r.org/ Slic3r takes STL files as input. Essentially what it does is take the STL solid and split it into a series of Z axis sections. Each section becomes a GCODE profile, which is used by the printer to make the objects.

Printrun

Printrun is described here: http://reprap.org/wiki/Printrun Printrun (specifically, pronterface) connects to the printer, controls the motors, measures the temperatures, and sends the GCODE to the board for interpretation.

Configuration Files

Configuration files are very specific to each printer, and each type of filament. If you change printers, and sometimes if you change filaments, you will need to tweak the slic3r configuration files. Most likely, you won't need the firmware / Marlin config for normal operations. To get the configs, either ask someone at the space, or get them from here (requires GIT) https://github.com/KnoxMakers/3d_print.git

Procedure

Create the GCODE

Open up slic3r. Go to File->Load Config. Load the above config. Drop your STL file in slic3r. Adjust settings as needed (default fine for most prints). Export G-Code to save it for use in pronterface software.

Connect to the Printer

Load Printer Interface (pronterface) software. Connect to printer... You may need to select the port to use.

Load the GCODE into pronterface

LEGACY DESCRIPTION (needs to be cleaned or deleted)

The group is pooling resources to create a Makerspace owned 3D printer. Andronicus is leading the efforts, with a build goal deadline of 1/15

Current Status

As of 02/19/2013, the space printer is printing parts with some degree of accuracy. Hardware and software changes frequently.
