Since Version 0.2.0 print3r supports remote printing:

Client Side

USB Connected 3D Printer

In order to make an USB connected 3D printer available on the local network:

print3r client

if you have multiple printers connected, use --device=/dev/ttyUSB1 etc to launch for each printer this client process. By default the process runs in the foreground, use & to launch as background process.

print3r client &
print3r --device=/dev/ttyUSB1 --baudrate=230400 client &
print3r --device=/dev/ttyUSB2 client &

Further, the printer must be connected with common baudrate like 9600, 19200, 38400, 57600, 115200 (default), 230400, etc but not 250000 (default in Marlin).

IMPORTANT:

  • by default there is no authentication required to connect and control your 3D printer(s) once print3r client is running
  • it is up to you to secure your local network, e.g. to put up firewall and secure the connnections
  • by default port 3380 is used for /dev/ttyUSB0, and port 3381 for /dev/ttyUSB1 and so forth

WIFI ESP3D (ESP8266/ESP32) Enhanced 3D Printer

You may attach an ESP8266 or ESP32 with ESP3D firmware, and connect it to the 3D printer controller board; once running configure through the web GUI the Data Port: 3380.

In the printer profile, and/or if you set with --baudrate=... when using print3r, choose the same baudrate as defined in the ESP3D settings.

  • ESP8266: Wemos D1 Mini (DHCP, baudrate=115200); Mainboard: RAMPS 1.4 + Atmega 2560; Wifi Hotspot: Belkin N600 2.4GHz 11g; print3r-host (Ubuntu 18.04 LTS) connected via Ethernet to Wifi Hotspot; 3D Printer: Ashtar K #2: success
    • 2.2hrs printjob finished correctly

Host Side

To connect to the remote client, use --device=tcp:<remote-ip>; if you have multiple printers connected to the client, add :<n> like :0 (default) or :1 and so forth, this number corresponds with /dev/ttyUSB<n> on the client-side.

print3r --device=tcp:192.168.0.16 --printer=prusa-i3 print 3DBenchy.stl
print3r --device=tcp:192.168.0.16:1 --printer=ender3 print 3DBenchy.stl
