1.2  Your deployed Portabee GO should now look like the following


2. Connecting your Portabee GO to PC/MAC

2.1  Locate the Micro-B connector on your Portabee GO.

2.2  Connect your Portabee GO to a PC/MAC using the USB-A to Micro-B cable provided.


3. Powering on your Portabee GO

3.1  Locate the power input connector on your Portabee GO.

3.2  Connect your Portabee GO to an electrical outlet using the power cord (with adaptor) provided.


C. Software Set-up

1. Installing the software


MAC

  • Drag the PortabeeGO_Cura file into your Applications directory
  • Run the App
  • Choose “Other -> Next -> Portabee_GO_Mobile_3D_Printer” during first setup


WIN

  • Run "Cura_for_PortabeeGO_Setup.exe"
  • Run "Pronterface_for_PortabeeGO_Setup.exe"
  • The software is ready and configured for your GO


2. Drivers


MAC

No drivers are needed for MAC, and CURA will auto-detect connection details for you.

If CURA has trouble finding the device, you can do the following:

  • Open a terminal (Go > Utilities > Terminal) and enter:  ls /dev/cu.*
  • Look for a connected device that says “dev/cu.usbXXXXX” (or similar).
  • The  “dev/cu.usbXXXXX” (or similar) device is your 3D printer


WIN

  • Open “Device Manager” and look for “Other devices”
  • Look under “Other devices”
  • You should see “Unknown device”

  • Locate the Drivers folder in the software package unzip location
  • Right click “Unknown device” and choose “Update Driver Software…”
  • Select “Browse my computer for driver software”
  • Click “Browse” to specify the location which contains the driver

  • Windows will install the driver. “Device Manager” should show “Arduino Mega 2560 (COM#)” under “Ports (COM & LPT)

  • Take note of “COM#”. This will be used later for the printer controller software


3. Printing Temperatures

Printing temperatures are as follows:

1.25 GO

190 Degrees C

1.0 GO

210 Degrees C


 1.25 GO - round extruder (2015+)

 

1.0 GO - square extruder (2014)

There is new start.gcode for 210 degrees in the
folder “GO_1.0_Model”


MAC


The temperature is set in the Basic -> Printing temperature (C)” area of
CURA.


WIN


The temperature is set in Pronterface in the “Heat: 190  [ SET ]” area.

* Temps are pre-configured to 190 degrees with software install


3. Pre Loading PLA Filament

3.1  Loosen the hex screw (right turn) and then push your filament through the drive gear assembly. Ensure that the filament is within the drive gear of the extruder.

- Feeding PLA filament into extruder -

The hex screw with the spring assembly can be turned to tighten or loosen the grip.

If during printing the filament is slipping, the gear is too loose:

  • turn left to tighten

If the extruder motor is struggling during a print, and making clunking sounds, the gear is too tight,

  • turn right to loosen.


5.1  Printing Process for MAC


MAC

  • Start up CURA by clicking on the shortcut
  • Press the rounded "Load" button
  • Locate the "SampleObject.stl" file

  • Press the rounded "Print via USB" button
  • Press the small "Connect" button
  • Click the small "Print" button to commence the 3D print proper

  • Your Portabee GO will begin to heat up, "Temperature: X" will show increasing values

  • The print will begin as the nozzle temperature becomes within range.


5.2  Printing Process for WINDOWS


WIN

CURA

  • Start up CURA
  • Press the rounded "Load" button
  • Locate the "SampleObject.stl" file
  • File ->  Save GCode

PRONTERFACE

  • Start up Pronterface
  • Enter "COM# @ 250000" next to the Connect button,
    you can find COM#  in
    Device Manager -> Ports (COM & LPT)
  • Press "Connect"
    If the console just sits at "Connecting...", press reset until connect
    (Some windows environments contain a small bug that requires this step)

  • Press "Load File"
  • Locate the saved gcode file from the CURA section above
  • Make sure the temperature is "Heat: 190"  
  • Press "Set"

  • Wait for the nozzle heat is ranging within 180-190 degrees
  • Press "Print"

  • The 3D print will begin.


D. Software Reference

1. Pronterface Settings

1.1  Pronterface is used for controlling Portabee GO. Pronterface is open source software that is produced by Kliment.

You can view more info here: https://github.com/kliment/Printrun

1.2 Here are recommended settings for Pronterface:


Do not use the Z-home button in Pronterface
Portabee GO has its own auto-leveling for the Z axis


B. Slicing Software – Cura Settings

2.1 We recommend Cura for preparing 3D models for 3D printing. Cura is open source software that is regularly updated by our excellent friends at Ultimaker.

E. Troubleshooting Guide

1. Extrusion Troubles

If the melted filament doesn’t seem to flow out of the nozzle smoothly or flows out unusually slow without the help of your pushing of the filament, adjust the grip of the drive gear and bearing.

This can be done so by tightening or loosening the countersunk screw a little. By tightening the screw, the gap between the drive gear and bearing will increase. Loosening the screw will cause the gap to decrease.

You must find the optimal gap that will provide the correct pressure and allow the filament to grip and extrude well.

- Check the tightness of the extrusion mechanism -


2. Auto Levelling

If the nozzle isn’t probing the points well and continues to go right into the depressed points, check if the nozzle tip is clean.

You want to use tissue paper and a pair of pliers to carefully remove all filament from the nozzle tip before the GO does its auto levelling routine.

The nozzle should not be oozing filament before the auto levelling, so retract the filament a bit, and let the extruder sit for a few seconds and then do a quick clean of the tip.

For perfect auto-level accuracy, a clean nozzle tip is the way to go.

To prevent the filament leaking out of the nozzle tip during auto leveling, we recommend to set the heating  temperature in Pronterface to 158 degree Celsius before start print. Make sure the start gcode mentioned in page 30 is included.
