Five different ways to upload your gcode files to #GCodePrintr App.

In order to print a gcode file you need to transfer it to the GCodePrintr App first. GCodePrintr allows multiple ways to transfer the GCode file:

1) Network Receiver

The “NetworkReceiver” allows GCodePrintr to receive Gcode files over Wifi (assuming your tablet/phone has wifi connectivity). Once enabled in the printer connection preferences (“Activate networkreceiver at start”) it will listen to port 53232 for incoming data. In order to send data from the PC, it is recommended to use the GCodeSimulator for PC Java application. (Download from here )
To send a gcode file:

  • A) Open GcodeSimulator application
  • B) Press the load button to load the gcode file
  • C) You can watch the simulation to spot any errors in the 3d print
  • D) Press the “send” button to open the send dialog
  • E) Enter the IP address of the tablet or phone (the IP can also be found when touching the GCodePrintr status bar below the console)
  • F) Choose “Autostart print” if GCodePrintr should start printing after the file has been transferred (requires that the USB connection has been established already)
  • G) The App should now show the “loading” dialog and receive the gcode file

Step A & B can be skipped if you add GCodeSimulator as a post-processing script for your slicer (see separate FAQ entry below)

2) Web Interface

GCodePrintr has a web interface to control the printer through a web browers (e.g. firefox). Once enabled in the printer connection preferences (“Activate webserver”) it will listen to port 2323 for http requests.
To send a gcode file:

  • A) Get the IP address of your tablet/phone (the IP can also be found when touching the GCodePrintr status bar below the console)
  • B) Enter the address and port in your browser (e.g. http://192.168.0.1:2323)
  • C) On the GCodePrintr web interface, press “Connect to Printer” to establish the USB connection (This might require some manual confirmation on the tablet/phone)
  • D) Click the “Browse” Button to select the gcode file and press “Upload File”
  • G) The App should now show the “loading” dialog and receive the gcode file

3) Google Drive, Dropbox, etc.

GCodePrintr can open files from popular cloud storage apps like Google Drive, Dropbox, etc.

  • A) On the PC, store your gcode file on the cloud storage.
  • B) Then go to the tablet/phone and press the folder symbol in the GCodePrintr app (upper left corner).
  • C) Choose the Folder+ icon to open the Android file manager (you might need to install a file manager app first)
  • D) Select the cloud storage and choose the gcode file to open

4) Use Slic3r/Cura send to Octoprint feature

The popular open-source slicer Slic3r and Cura have a feature to send gcode directly to OctoPrint servers. GCodePrintr will listen to OctoPrint style requests and accept those file uploads. Once the webserver is enabled in the printer connection preferences (“Activate webserver”) it will listen to port 2323 for http requests. In Slic3r/Cura just enter the IP address and port of the GCodePrintr Web Interface (e.g. 192.168.0.99:2323) in the Octoprint field and try it out. (no API key required)

5) Open from local storage or SD card

GCodePrintr can open files from local storage or SD Card. You can copy the gcode file from you PC to the tablet/phone using standard Android mechanisms. e.g. through USB connection, put SD card in, bluetooth, …. Once the file is copied, open it in the GCodeprintr app.

3D Printed Wheels for Bosch Indego

My Bosch Indego lawnmower sometimes gets stuck when climbing the small hill im my garden. It often happens when the weather was rainy and the grass is wet. The wheels just slip through.

I found a great design for new wheels on thingiverse which should improve the traction of the wheels significantly. The print took ~13h and the material cost is about 8€ per wheel.

GCodePrintr + Prusa I3 MK3S. A great duo !

My new Prusa I3 MK3S arrived and I run the first few prints.
I’m very happy with the print quality and reliability of the printer so far. There are a few improvements I need to add to GCodePrintr to better handle some Prusa specific stuff (e.g. filament run-out).

Prusa I3 MK3S arrived 🙂

MTB Flak Trail

Am Wochenende ging es mit dem Cube Fully Richtung Bad Kreuznach auf den Kuhberg. Dort gibt es allerhand Trails und schöne Wege durch den Wald.

Zuerst sind wir ca. 300 Höhenmeter über Fürfeld auf den Kuhberg hoch. Dabei kommt man am Schäferplaken (Eine große Kreuzung mit 7 Wegen) vorbei. (Und später noch ein paar mal … Alle Wege führen nach …)

Vom Schäferplaken geht ein gemütlicher Trail Richtung Waldheim. Der Trail hat eine kurze steile Passage (Die Kuhle – https://www.komoot.de/highlight/185608) die es in sich hat.

Nach einer Erfrischung im Waldheim geht es Richtung Westen einen Waldweg entlang der sich schön bergab am Berg entlang schlängelt und danach ein steiler Anstieg der auf dem Schäferplaken endet.

Falsch abgebogen….aber eine schöne Aussicht

Vor dort geht es wieder Bergab Richtung Altenbamberg. Nach einigen Kurven und Abzweigungen haben wir durch Zufall den Flak Trail entdeckt (https://www.komoot.de/highlight/407606). Der Einstieg zum Trail ist schon gleich sehr knackig und es gibt einige Gelegenheiten um kurze Sprünge zu machen. Aber Vorsicht, die nächste Kurve kommt meistens dicht danach.

Da wir nicht voll ins Tal nach Altenbamberg hinunter wollten, haben wir nur den ersten Teil des Flak Trails gemacht und sind dann den Uhu Trail Uphill bin zum …. ratet mal …. dem Schäferplaken 🙂

1) Flak Trail Einstieg

Von dort ging es dann die 20km zurück nach Hause.
