Allows you to print from Cura to your 3D printer connected to an ESP8266 module.
UNDER DEVELOPMENT. See Issues. Pull requests welcome!
The esp8266/Arduino sketch ESP8266WirelessPrint.ino
is uploaded to a ESP8266 module.
Before you compile this, you need to create a file called private.h
in the same direcory as the sketch. It should contain:
const char* ssid = "________";
const char* password = "________";
This should be replaced by something more elegant. Pull requests welcome.
As or March 2017, this code compiled on Arduino hourly and esp8266/Arduino git master.
The ESP8266 module is connected with your 3D printer via the serial connection and to a SD card (acting as a cache during printing).
You need to connect
- TX, RX from your 3D printer to the ESP8266 module (EXT-1 header on RAMPS boards)
- Power and GND from your 3D printer to the ESP8266 module (attention, the EXT-1 header on RAMPS boards has 5V while the ESP8266 needs 3.3V)
- SD card to the ESP8266 module
- A capacitor across the power pins of the SD card
Using a SanDisk 2 GB card formatted with the SD Card Formatter from the SD Association seems to work for me. Also, putting a capacitor across the power pins of the SD card appears to increase the probability of the card being recognized.
To print, just open http://3d.local/ and upload a G-Code file using the form:
Ycan also print from the command line using curl:
curl -F "file=@/path/to/some.gcode" http://3d.local/print
Cura plugin which discovers ESP8266WirelessPrint instances using Zeroconf and enables printing directly to ESP8266WirelessPrint.
- Make sure your Cura version is 2.4 or newer. On Linux, download Cura-2.4.0.AppImage.
- Download or clone the repository into [Cura installation folder]/plugins/WirelessPrinting
or in
~/.local/share/cura/plugins
on Linux. The folder of the plugin itself must beWirelessPrinting
mkdir -p ~/.local/share/cura/plugins
( cd ~/.local/share/cura/plugins ; git clone https://github.com/probonopd/WirelessPrinting.git )
- Make sure WirelessPrint is up and running, and the discovery plugin is not disabled
- In Cura, add a Printer matching the 3D printer you have connected to WirelessPrint
- Select "Connect to WirelessPrint" on the Manage Printers page.
- Select your WirelessPrint instance from the list
- From this point on, the print monitor should be functional and you should be able to switch to "Print on " on the bottom of the sidebar.
