Prototype Gigabot X printer user guide

This guide will walk through the steps to successfully operate the prototype Gigabot X from Re3D.

Printable Materials

So far, the Gigabot X has been tested and proven to work with the following pellets:

Virgin PLA, with MasterBatch Mixing

Recycled PLA from failed 3D Prints

Recycled ABS

Recycled PET

Recycled Polycarbonate

Recycled ASA

Recycled Polypropylene

How to use

Power and Lights

The power can be turned on via a small toggle switch on the top of the printer. The lights can be unplugged via a small connector behind the wire organizer on the top of the printer.

Interface

The interface is just like any other RepRap 3D Printer. It does use a mini SD card instead of a full size one however. Also there are two extruders, extruder one is for the bottom heater and extruder two is for the top heater on the extruder.

Slicing

Build size: 560 X 710 X 600 (mm)

Extruders: 2

Heated Bed: Enable

Enable Cooling: Off

Nozzle Diameter: 1.75mm

Retraction: 14mm

Retraction Speed: 20mm/s

Purging Materials

To purge from one material to another, a g-code has been made to purge 8000mm worth of material through the extruder. This process takes about 20 minutes to complete and sometimes needs to be ran several times to get all the old material out of the extruder.

Make sure to remove hopper extenders, and clean out any remaining material in the hopper with a vacuum, this reduces the amount of time to purge to the new material.

When purging from a high temperature plastic such as polycarbonate to a lower temperature plastic such as PLA, it is best to step down to the temperature by first purging to something like polypropylene or ABS and then purging to PLA. This reduces the chance of the PC clogging and the PLA burning.

More testing is required with extrusion purging compounds to see if they are worth buying and using.

New Material Testing

For new materials, a line test is performed. More information can be found here on the Speed vs Temperature Line Test: (Link) Once the line test is complete, the sweet spot for print speed and extrusion temperature is obtained and can be used for optimum results on the Gigabot X.

Tips and Tricks

If the SD card menu gets really slow, reformat the sd card on your computer. instructions here: https://www.sdcard.org/downloads/formatter_4/
