GT2560 is a compact board that is integrated with the mighty function of the  Arduino Mega2560 +Ultimaker and Arduino Mega2560+ramps 1.4 on respect of both software and hardware and has more premium features: the streamlined interfaces effectively avoid the unnecessary troubles, well-regulated compaction of components highly integrated saves more space and easier to be mounted on most applications.

 

5 stepper motors, swappable driving modules, mighty ATmega2560 processor with 256k memory, 16MHz operating frequency, high-performance USB serial converter FT232RQ, all these make the GT2560 an ideal option for a 3D printer control board. What’s more, GT2560 can run over 12V to 24V which gives higher torque and higher rotation rate.

Update log:

1. A 3-pin straight pin is added to connect with 3D touch auto leveling sensor.

2. The USB connector will not provide 5V for the board, if you need to refresh the firmware, please provide external power supply.

3. The power port has been changed from hollow to solid one to provide higher current-carrying capability.

4. The three heater connecter has been changed into blue ones: 2-pin RC301 5.0mm 15A

Features:

1.Integrated with the mighty function of the Arduino Mega2560+Ultimaker and the Mega2560+ramps 1.4 kit , GT2560 can not only take full place them on respect of both software and hardware, but also features compact size, more convenient connection, and more stable.

2. Adopt ATmega2560 as the main control chip, coupled with the high-performance USB serial converter FT232RQ.  

3. The power pack: operating voltage is 12V-24V; double power supply design feeds for heatbed and logical part separately. The current is 12A for heatbed and 5A for other parts. The cooling fan can support 12V

4. The main circuit adopts SMD fuse tube, the diode added to the power port can provide reverse protection to the whole circuit, in addition, the 5V USB is USB port protected with 500mA Recoverable fuse.

5. 3 12v fan output and one PWM output for LED or other lighting equipment.

6. 3 55Amp MOSFET (with LED indicator, the actual output is restricted by the PCB board and the connector), all 3 MOSFET are equipped with heat sink to ensure sufficient heat dissipation and stable operation.

7. Support 5 A4988 stepper drivers (3 for X/Y/Z axis, and 2 for extruders); the subdivision of stepper motor can be setup by dial switch, eliminating jumper caps, easier to operate.

8. 3 temperature sensor input (100k thermistor is recommended)

9. Extended LCD and SD card interface support both LCD2004 and LCD 12864, with which you can print without your PC.

10. The firmware is the prevalent Marlin, which is known for its stability, usability, and high-performance.

  • Linas Paulauskas | 02/11/2017

    Hello, I have bought Reprap Prusa i3 Pro-B from ebay and it contains GT2560. It was working fine and I have no issues printing from USB, the issues started when I started upgrading the printer with lead screws and I needed to changed steps on z-axis. It seems printer board doesn't accept instruction from programmer. I am not sure what I am doing wrong and whenever the board is any good. I am suspecting that maybe programmer on boars is either not loaded or was removed after programming. Now my question is whenever I can update setting in the board to work or I need to buy new board, but I don't want to do it before making sure new board is the only option. Here is more information regarding my issue, I have raised it in Arduino forum: https://forum.arduino.cc/index.php?topic=431223.new#new

    • Zina Luo | 02/13/2017

      hello Linas,ask our techncian for help and will feedback to you.

      • Linas Paulauskas | 03/27/2017

        Hello, again. Thank you for your response. I haven't heard any update, but just though maybe I would be e-mail to your technician directly. I am thinking to order boot loader or maybe send the board for repairs, but want to be sure what is wrong with it .. so that I cannot load firmware to it. Can you advise which e-mail should I use. Thank you

        • Zina Luo | 03/30/2017

  • Bernard Bout | 08/31/2016

    I have a Geeetech Full Aluminium 3d Printer with a Sanguinololu board. I want to upgrade the Sanguinololu to this board. 1. Will I need new stepper drivers or can I use the ones from the old board. 2. Are there any changes needed top be done to the firmware to make this work on my printer? 3. Where can I get the latest firmware for this board and my printer? I notice that this board is included with the Geeetech Aluminium Pro printer. Will that firmware work with my printer?

    • William Kwok | 08/31/2016

      1.You can use the old ones if they're all working fine.2.You can download the following firmware from here:http://www.geeetech.com/forum/viewtopic.php?f=20&t=17046 (Prusa I3A 2560.zip, I3_pro_X.zip,Marlin-PI3_Pro_B.zip)The three firmares all fit your printer.

    • William Kwok | 08/25/2016

      Hi,Shiva I'm afraid it doesn't support the LCD you mentioned,and about tht PSU,the operating voltage is 12V-24V; double power supply design feeds for heatbed and logical part separately.


  • Etienne Boucher | 08/09/2016

    Hi, I had this board for about 2 weeks and ran it on stock a4988. It ran fine, but I had drv8825 and when I try them at about .6v the motors make more noise and the board heat so much (I have 2 60mm fan on it) and I put an heatshink on the hot part. The drv are not very hot but the black thing between the second extruder driver and the .150 thing become crazy hot. Can I broke the board by printing like that or do you have an idea about what is happening ?

    • William Kwok | 08/09/2016

      Hi,did you plug your drvs in a wrong direction?Cuz its plugging direction is different from A4988...And when you plug drv,you should change the subdivision of the motor(yes it the jumper caps,drv with one cap and A4988 with 3 caps as you saw).Finally,A4988 is recommended.


  • William Kwok | 07/19/2016

    Hi,Bob 1.Did your extruder motor work before?You can try swapping the extruder motor cable with cables of other motor,sometimes the motor cable is broken though it rarely happened. 2.About the engine wiring diagram,you can find it in the "Users Manual of GT2560.pdf" on this page.


  • Bob Wood | 07/19/2016

    Extruder motor on my 3D printer stopped working. I did replaced the Driver-A4988-Module. It does not help. Is it possible find the engine wiring diagram to the chip Atmega 2560


  • david c | 07/15/2016

    ok i keep on getting time out when trying to upload to the bored.. i can see it with pronterface and print with it. just wont let me upload the firmware.

    • rita xiang | 07/17/2016

      Did you disconnect the board to the Repetier host or other soft ware you are using? if so, please disconnect it first and try again.

      • david c | 07/22/2016

        might sound silly but how do you do that thx

        • rita xiang | 07/22/2016

          i mean if the board is connected to the Repetier host(The software you use to control your 3d printer). If so, please disconnect it. If you still have problem with it, please contact our tech support at technical@geeetech.com he will help you upload firmware with remote control


  • Pablo Arturi | 06/30/2016

  • Frank Mizzi | 06/21/2016

    I have asked this question without getting an answer. Q:What is the warranty on the boards. I ask this because I have had my heater bed connection melt and burn weld it's plastic to the base of the plug and melt the solder and fall off the board and that a possible transistor is the culprit, and that I also have a noticeable scorch/burn mark on one of the (4 pin) power lines on the main connector,from the power supply, so could also be the power supply.

    • rita xiang | 06/21/2016

      Hello Frank, the warranty is 180 days. We have changed the bed heating connecter into the blue one as you can see in the picture, the melting will not happen again. Regarding to the burn mark on the power supply connector, pay attention that never hot Plug andUnplug the wire.

      • Frank Mizzi | 06/23/2016

        Was anything else replaced because i can see a light brown mark on the track from the transistor. As I stated in my comment I have a scorch mark on one of the lines from the power supply at the plug on the board and was concerned that it might have been a power supply issue than from a plug issue. mainly from the fact that the track on the board from the transistor to the plug was also slightly burnt in a light gold tint, making it look like was getting hot as well. I am trying to supply you with as much information as I can from what I can see. I have recently ordered a board of a seller on ebay as of no shipping cost, but that it is of the older type of board, and that I have concern of this happening again but wonder if just replacing the plug will be enough to solve it as I could do that my self with a soldering iron.

        • rita xiang | 06/26/2016

          thanks for your information. Currently, we only changed the connector. You can send more pictures to me: rita.xiang@geeetech.cn

          • Frank Mizzi | 07/10/2016

            I bought another board from an ebay seller but that it was void of firmware. I am wondering if you have a proper copy for this board for I3 as I received a copy a long time ago from someone at Geeetech, that I uploaded it via arduino software and nothing responds as it should, do I have to mnually configure the firmware, or is there a copy that is preset for i3 on the Geetech forum/site,, as I cant get to the forum as I dont have a pass word and my main password seems not to work , /I was wondering if any one at Geeetech can email me a proper copy please.


  • Wellington Costa da Silva | 06/13/2016

    This controller board can be used in a printer D -bot CoreXY ?

    • rita xiang | 06/15/2016

      i do not know the printer D -bot CoreXY, but most control board are compatible. If this control board has the feature you need on that printer,you can use it.

  • Kurt Rozario | 05/12/2016

    Hi All. I am using a GeeetechGT2560 controller board, with Davinci 2.0 hardware. My Extruder extrudes well under manual control, (from PronterFace or Repetier-Host), but, during prints, its stops extruding, after a few layers and starts clicking or skipping. A) I have tried several times to adjust the potentiometer on the extruder motor driver board, A4988, finding the right point between when the motor stops turning, when the power is too low and the motor stops turning when the power is too high. As I mentioned, it works smooth under manual control. I still cant get more than 2 or 3 layers to print, because, somewhere after the first few layers, between 2 and 5, the extruder motor starts skipping. B) I have tried printing in PLA at 185 and 190 degrees. The clicking starts either way. C) I dont believe the motor is getting overheated, as it starts clicking after just a few layers being printed. It only feel warm to touch at this point, often, even room temperature. D) The Da Vinci 2.0 has two extruders. I have tried both motors, with different cogs and idlers, both with same results. Hence, I am sure the motors/cogs are not faulty. E) I have tried two different Motor Driver Boards, A4988's, on the same output on the GT2560. Same results. F) I cleaned the nozzle several times, confirming each time after cleaning, that PLA flows freely, through the nozzle, under manual control. G) I have tried slicing with Slic3r and Cura. Print preview shows XY movement and X axis and Y axis move accordingly. I have no idea what to try next as I am out of ideas. Any and all help is greatly appreciated. I have spent a month now, trying to install this GT2560 and still cant get a print done.

      Hi, sorry to tell you that it can not be used on this board.

    • Mariusz Matłosz | 12/17/2016

      Why not? You have to connect "+" to 5V on board (lower left side of atmega chip, next to C37). Signal to SIG, ground to GND (on temp JST slot). You also need to desolder R23 for 1st head thermocouple, R21 for 2nd and R4 for heatbed. These three resistors are located below temp JST slots. If need only for head, desolder only R23. It is exactly mega + ultimaker board. Even names are the same. It will void warranty for sure.

    • Quentin Qiu | 02/04/2016

      Hi please check your e-mail, firmware has been sent to you.


  • Michael Shievitz | 01/11/2016

    Will you post a pins.h file for the GT2560 board please. When setting up Repetier firmware be best choice I have found so far is the Ultimaker 1.5.7 shield, but this board lacks full pin defines. What pins control PWM_FAN, FAN_1, FAN_2, FAN_3 My best guess from the forums and other research is that they are pins 16, 4, 5, 6

  • Steve Gigr | 12/06/2015

    Hi Quentin, I have this board on my I3 pro with the dual heads. Can / will this board support the 2-in-1 out head? If so could you send me the firmware and the instructions if any? Thank you sdigrazia1@sbcglobal.net

    • Quentin Qiu | 12/07/2015

      Hi Steve, sorry to tell you that GT2560 can not be used on your printer.


  • Rene Jurack | 11/23/2015

    I am looking for the type of Connectors used for the motor- and fan connectors. Are you selling these also?

    • rita xiang | 11/24/2015

      not for retail, if you need large quantities, please contact our sales Rannie.


  • peter boric | 11/19/2015

    Hi I still dont understand things about power supply. One power supply I can connect 24v for my 24v bed and one power supply is for everything else so I can connect it to 12v is that correct ?

    • Quentin Qiu | 11/22/2015

      Hi Peter, hot bed and logic circuit part are separate in power supply.


  • eduardo nieve | 11/14/2015

    HI, ANYONE HAVE THIS PROBLEM? : step1: i turn on my laptop -_ i connect the GT2560 by USB cable to my laptop -_ my laptop recognize the motherboard as USB device -_ i open repetier-host (configuration COM and baudrate OK)-_. i turn on my Prusa I3X ...and the connection is lost :c step 2: the same procedure, but, i disconnect the power supply of my laptop (working only with battery) ...and all works fine. wtf? is a kind ground problem??. anyone have the same situation??

    • Quentin Qiu | 11/17/2015

      Hi, what is the operating system of your computer, Windows OS or Mac OS?

      • eduardo nieve | 11/22/2015

        i use win 7. the was fixed connecting the printer on other electric point. But,... wtf? anyone have the same situation?? also, i have to mark the 'fase' and 'neutro' of all points electric.


  • Alek Mal | 10/06/2015

    Hi. All stepper motor input the same functionality (I want use it with 4 independent axis and 1 extruder)?

    • Quentin Qiu | 10/08/2015

      Yes they are, but you have to do modification yourself if you want to use it with 4 axis.


  • VLADIMIR AFANASEV | 10/05/2015

    Hello. Please send me firmware for Geeetech Prusa I3 X 3D printer. Thank you.

    • Quentin Qiu | 10/07/2015

      Hello,please tell me your main board type and leave your e-mail address.


  • Pierrick Dore | 10/03/2015

    I installed Repetier Firmware (Motherboard: Ultimaker 1.5.7) into your GT2560 (mounted on a GT2 Delta 3D printer). The firmware works except the 2004 controller (with config : "Smartcontroller for ReprapDiscount on Ramps"). Could you send me the custom configuration to run the GT2560 with Repetier Firmware please. Repetier Firmware is better for auto-level and with Repetier Host. Thank you.


  • Joe Cross | 09/18/2015

    Will this work in a CTC dual-extruder printer? What firmware is pre-installed and what firmwares are supported?

    • Quentin Qiu | 09/20/2015

      Hello Joe, yes it can work in a CTC dual-extruder printer. Pre-installed firmware is Marlin firmware, but it is designed for Geeetech's printer, so there may be some differences between it and that of CTC. About the firmware you can consult the original factory for help.


  • Evan Morris gachiri | 09/17/2015

    hey i need the gt2560 firmware i bought the 3dprinter from you some one moth ago here is my mail megasonlinejobs@gmail.com

    • Quentin Qiu | 09/17/2015

      Hello Evan, would you like to tell me which printer you bought?I need know the type of your printer in order to send the corresponding firmware to you.


  • Eugenio Rojas | 09/03/2015

    Hello, Can this support dual extruder? Expects says it support 5 steppers, but Z axis on prusa requires 2 stepper motors.

    • Quentin Qiu | 09/03/2015

      Hello Eugenio,it can support dual extruder,the 2 motors of Z-axis only occupy one slot

    • rita xiang | 09/04/2015

      yes, it support dual extruder, from the picture you can see there are 6 slots for steppers,and the two z axis steppers are in parallel-connection,so you just need 5 A4988 for the steppers. you can check the schematic diagram in wiki.


  • roman zahora | 07/30/2015

    What type is fuse for power supply unit GT2560 - located at left corner . they are white - 2 of them. and where I can order ?

    • Quentin Qiu | 08/31/2015

      Hello Roman, they are resettable fuse, their specification is SMT5*10, one of them is the type of 0154010.DRT, 10A/125V, and its location on the machine is F1;the other is the type of 0154015.DRT,15A/125V,its location is F3. You can buy them in local hardware store or order them online.


  • Paul Chase | 06/11/2015

    If you run the board at 24 volts are the fans regulated to 12v, or are they just 24v too? Considering this as a replacement for the RUMBA board, and that seems to be the only thing (other than 3rd extruder) missing.

    • Anxiang Weng | 06/15/2015

      Yes, no matter you use 24V or 12V input voltage, the output voltage for fan is 12V.

      • Harold Reedijk | 08/13/2015

        I'm a bit confused, support told me that when I connect a 24v power supply, also the hot-end heater and all other connectors will have a 24volt output, including the PWM fan and non controlled fans.
