3D Fox is an Android App to control and monitor 3D printers via Wifi, Bluetooth or USB OTG/Host port.

It is simple to use, has a clear and meaningful log screen and works great on small/inexpensive devices as well.

Developed with a Reprap Prusa i3 with Mega2560+Ramps+Marlin, Wifi module ESP8266 and BT module JY-MCU, it should work with many other HW/SW combinations.

Basic features:

  • XYZ and extruder movements
  • T1, T2 and Tbed
  • Print from Android device
  • Upload from Android device to SD
  • Print from SD
  • Custom buttons
  • Log screen, large and easy to read

Special features:

  • Wifi connection.
  • Web interface to monitor printer and to upload/print files from your PC/Tablet browser over the network.
  • Take back control of SD card printing jobs after connection with the printer is lost. You can use this feature to manager several printers with the same device.
  • Transfer speed is 2-3 times faster than most of the other Android apps out there, a must for printing objects with a lot of small moves, or when using Bluetooth communication.


USB connection:

CDC ACM (eg Arduino Mega)
FTDI (eg Melzi, Sanguinololu)
CP210X, PL2303

Wifi module ESP-01 (ESP8266 chip) successfully tested:

  • Hardware: ESP-01 + Arduino adapter
  • Firmware: transparent bridge 'esp-link' by JeeLabs
  • Baud rate: 250000.
  • Upload speed: 1 MB transferred in 100 s (with Mega2560+Marlin), comparable to USB connection speed.
  • Antenna: performances boosted with this improvement

Bluetooth module:
