By measuring the Vref voltage in the motor drivers of the Azteeg X3, you can find and adjust the corresponding current limit for each driver.

Recommended Motor Driver Vref in 12V system

  • X motor driver - 0.84 volts
  • Y motor driver - 1.2 volts
  • Z motor driver - 1.0 volts
  • Ext motor driver - 0.84 volts

Recommended Motor Driver Vref Voltage in 24V system

  • X motor driver - 0.84 volts
  • Y motor driver - 1.1 volts
  • Z motor driver - 0.8 volts
  • Ext motor driver - 0.84 volts


We recommend using Arduino IDE version 23 to load the firmware into gigabot's brain (aka azteeg controller board). This version is necessary to be compatible with some of the library's used to run the lcd screen, although it is possible to use the latest version of Arduino if libraries are carefully configured.

There are two versions of the firmware:
One supports just the Viki display. Download version (V3.1)
One supports the Viki display with Heated bed: Download version (V3.3)

You need to have Arduino set up correctly to perform this upload to your Gigabot. Whether you are on a Mac, PC, or Linux operating system, the Marlin library files, along with the supporting libraries for the LCD display, need to be copied to either the arduino install location "library" directory or the Ardunio sketchbook directory before the firmware will compile. If something here is misconfigured, that is where the "LiquidTWI2.h no such file or directory" error would come from.

The most current libraries for Marlin itself also need to be in the libraries directory. The version straight from Github can be found on Erik Zalm's Github repo. However, it may be easier to grab them from our direct link for Arduino Version 22 and 23, or Arduino version 1.x.x.

The LiquidTWI2 library also needs to be installed in the libraries directory for the Viki LCD portion of the firmware to compile. This library is located at Lincomatic's Github repo at:

Once your library locations are set up properly, the instructions for installing Marlin from are as follows:
"Configuring and compilation: Install the arduino software IDE/toolset v23 (Some configurations also work with 1.x.x)

Start the arduino IDE. Select Tools -> Board -> Arduino Mega 2560 or your microcontroller Select the correct serial port in Tools ->Serial Port Open Marlin.pde

Click the Verify/Compile button

Click the Upload button If all goes well the firmware is uploading

That's all. Enjoy Silky Smooth Printing."
