GTM32 is fully self-developed, open source control board by Geeetech for high-performance 3D printers. It keeps Geeetech’s uniformly optimized interface specifications, easy to assemble and with compact layout, high integration and high performance.

GTM32 control board (hereinafter referred to as the control board) adopts the current mainstream high-performance Cortex M3 core chip STM32F103, with its running frequency of up to 72MHz.The control board supports up to 6 stepper motors, namely, XYZ axial motors and 3 extruders. Users can replace the driving modules, such as A4988 and TMC2100 modules, according to their own needs. Besides, it employs the high performance USB serial chip FT232RL, which enables users to manipulate the control board via USB cable. Its output voltage is 12V.

LCD 2004 display is a basic 20 character by 4 line dot matrix controller module designed for different 3D printer motherboard. The product contains 20 Character x 4 Line LCD display, a rotary encoder and 30cm connection cables. There is a SD Card slot on the back of the LCD Module, connecting it with the controller board of 3D Printer. Just insert your SD card into the SD slot, you can print 3D models without PC. 

 

2. Features of GTM32

a. Adopting high-performance Cortex M3 core chip STM32F103, with its running frequency of up to 72MHz.

b. Using high-performance USN serial chip FT232RL, manufactured by FTDI, compatible with Windows, OS X, Linux etc. mainstream operation system.

c. The output voltage of GTM32 control board is 12V. It is characterized by dual power supply design, powering up the hotbed and other electronic components respectively. The current for hotbed is 9A and 7A for other parts.

d. The main circuit adopts in-line fuse, with overcurrent protection and reverse protection. The USB power supply interface has a restorable fuse, with its current at 500mA.

e. The control board features three interfaces for PWM fans.

f. Supporting up to 4 stepper motors, namely, XYZ axial motor and an extruder. The common stepper motor drivers are A4988 and TMC2100.

g. Dual temp sensor input: one for the extruder, the other for the hotbed. 100K thermistor is recommended.

h. The control board comes with expansion interfaces for LCD display and SD card, supporting stand-alone printing.

i. With a buzzer on board.

    Is it possible to just purchase ONLY the main board? I do not need the LCD or cables. Also, I purchased the Prusa I3 M201 a while back and have had a few major problems. The first being that The instructions included were incorrect, I believe they were for a variant of the printer or maybe a previous model. The second being that out of the box the GTM32 PRO VB board was COMPLETELY DEAD and got VERY hot. I confirmed this buy borrowing my friends main board from the SAME TYPE of 3D printer to test. Every other electronic component is WORKING including the LCD, Motors, Switches, Cables, Hotend, Hot bead and Power supply. The third being that there were significant tolerances in production which forced to make modifications to multiple parts of the Z-Axis assemblies and the hotend carriage. Thanks in advance :)

      Hello Brett, Thanks your suggestion, i have submited it to related person. GTM32 PROVB now is available on website, please search key words:gtm32


  • Richard Neal | 11/30/2018

    On an M201,I want to add a fan to use PWM to cool the part being made? Witch connector and what change in the software needs made? Thanks Rick

    • Jocelin Jia | 12/03/2018

      please connect it on extruder extension board, there will have a pwm port, thanks


  • Snir Ifrah | 11/04/2018

    What are the differences between the GTM32 Pro vb and GTM32 Pro vd?

    • Jocelin Jia | 11/05/2018

      VD still testing, so we can not provide more info to you ,thanks

      • Snir Ifrah | 11/05/2018

        I got the VD in my printer.... If it still testing, does it make sense ?

        • Jocelin Jia | 11/07/2018

          please do not worry,PROBD and pro vb is no big difference,VD upgrade from VBm the only difference is that VD board add one more driver port, thanks

          • Snir Ifrah | 11/09/2018

            Thanks for your response. I see that the vb has 6 drivers, and my vd has also 6.... Another question, I can confirm that TMC2208 working good on this board, but on X axis I just can't make it to work properly. Every time X home, it just disconnect and won't move. Any ideas?


  • Karel Pospíšil | 10/26/2018

    Hello, does this board support the TMC2208 drivers?

    • Jocelin Jia | 10/26/2018

      do not test TMC2208,TMC2100 can use it but need change the stepper direction, thanks


  • Brian Ipsen | 10/23/2018

    Is the board 24V capable ?

    • Jocelin Jia | 10/24/2018

      yes


  • James McElhany | 07/21/2018

    Bought 2 on separate orders paid $3,00 for tracking, shipped 7/11/2018. Both orders shipped with with the same tracking number LW047770205DE, unable to find with this tracking information. Looks like I wasted the $6.00 for tracking. Where is the package?

    • Jocelin Jia | 07/23/2018

    Can I pull 5V off the controller to power Octoprint?

    • Jocelin Jia | 07/06/2018

      the voltage of the lcd is 5v


  • James McElhany | 07/05/2018

    What is the difference between the GTM32 Pro and GTM32 Pro vb?

    • Jocelin Jia | 07/05/2018

      Hi James,NO big difference for the VA and VB ,VA have the SD card port and the wire connection is the different than VB, but the function is the same.


  • James McElhany | 07/04/2018

    Can I use this board on both my Rostock 301 and i3 M201 printers

    • Jocelin Jia | 07/04/2018

      Hi James, yes, it workable.


  • James McElhany | 07/03/2018

    How long is the ribbon cable? I am going to upgrade my older M201 printer to match the current model.

    • Jocelin Jia | 07/03/2018

      Hi James, please send mails to victory.lei@geeetech.cn ask for a long cable, thanks
