Configuring Marlin Firmware for the Fabrikator Mini

Research, Hardware modifications and Firmware config

Published on March 24, 2016.
Last updated on May 01, 2019.

Update:

As the Marlin Firmware is changing quite often, I’m maintaining a branch with my configuration on my git server. Get it like this:

git clone https://git.xythobuz.de/thomas/marlin.git
cd marlin
git checkout fabrikator-mini

---

I’ve recently aquired a Turnigy Fabrikator Mini V1.5 from HobbyKing. This is a very cheap 3D printer with surprisingly good quality.

Many 3D printers are based on an Arduino with some stepper motor drivers, commonly on a RAMPS shield. The Fabrikator Mini is using an MKS-Base board, which is basically an Arduino Mega (with an ATmega2560) and a RAMPS 1.4 shield on a single PCB.

I’ve also got the so-called RepRapDiscount Full Graphic Smart Controller, a graphic LCD, a beeper, some buttons to control the menu and an SD-card slot. It does, however, not work out-of-the-box, you need to compile a new firmware to get it to run.

As far as I can tell, the most common and actively developed firmware for these boards is the Marlin Firmware, but there are many alternatives.

The YouTuber Chuck Hellebuyck offers a pre-configured Marlin Firmware on his website, but it seems to be a very old version. That’s why I’ve decided to get the newest Marlin Firmware working on the Fabrikator Mini.

At the time of this writing, Marlin version 1.1.0-RC3 was the newest available firmware release. Clone the repository and check out the corresponding tag:

git clone https://github.com/MarlinFirmware/Marlin.git
cd Marlin
git checkout 1.1.0-RC3

The configuration happens in the files Marlin/Configuration.h and Marlin/Configuration_adv.h. It’s best to read through the whole file to get to know all available options. I’ve listed the important changes in the following section, including the changes required to get the display and SD card working:

// Configuration.h

#define TEMP_SENSOR_0 3
#define HEATER_0_MAXTEMP 230
#define HEATER_1_MAXTEMP 230

#define DEFAULT_AXIS_STEPS_PER_UNIT   {201.01,201.01,6366.88,97.11}
#define DEFAULT_MAX_FEEDRATE          {40, 40, 2, 40}
#define DEFAULT_MAX_ACCELERATION      {200,200,50,2000}
#define DEFAULT_ACCELERATION          300
#define DEFAULT_RETRACT_ACCELERATION  2000
#define DEFAULT_TRAVEL_ACCELERATION   300
#define PLA_PREHEAT_HPB_TEMP 0
#define PLA_PREHEAT_FAN_SPEED 127
#define ABS_PREHEAT_HOTEND_TEMP 200
#define ABS_PREHEAT_HPB_TEMP 0
#define ABS_PREHEAT_FAN_SPEED 127
#define SDSUPPORT
#define ENCODER_PULSES_PER_STEP 4
#define ENCODER_STEPS_PER_MENU_ITEM 1
#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

// Configuration_adv.h
#define EXTRUDER_0_AUTO_FAN_PIN 9
//#define ENDSTOPS_ONLY_FOR_HOMING // Comment this!

With its default firmware, the Fabrikator Mini by default runs the fan as soon as the extruder temperature exceeds 50 degrees Celsius. To get this behavior from the Marlin Firmware, EXTRUDER_0_AUTO_FAN_PIN is set to the same value as FAN_PIN. This leads to a compile error. To fix this, FAN_PIN has to be undefined. This can be achieved by modifying the pins.h file corresponding to the mainboard used, in this case Marlin/pins_RAMPS_13_EFB.h, adding these lines at the end:

// Disable normal fan to be able to enable auto fan
#undef FAN_PIN
#define FAN_PIN -1

// Reverse encoder direction
#undef BTN_EN1
#define BTN_EN1 33

#undef BTN_EN2
#define BTN_EN2 31

That’s it. You can now open the Marlin/Marlin.ino file in the Arduino IDE, select Arduino Mega 2560 as device and the Fabrikator Mini USB port and hit upload. If this is your first time compiling Marlin with Graphic LCD support, you need to install the u8glib from the Arduino IDE library manager.

The following is a git patch for all required changes:
