Development Environment Setting
Interface Connecting and Setting
Note:
Pay attention to the Plus-n-Minus of the power connector, reverse connection can cause irrevocable damages.
A4988 should also be connected to the right port, mismatches and revered directions can cause damage to the main board. Please notice the color of the pins and connect the same colored pins together. If some pins are not color-labelled, pleased follow the picture below.
Install Software
After downloading, double-click the .exe file to finish the installation.
Windows will prompt that a new USB Serial Port is detected, now you can check the device manager, you will see a new port named“USB Serial Port”
Then, windows will open the dialog box “found new hardware wizard”, check “no, not this time”, then click “next” to continue.
Then, windows will open the dialog box “found new hardware wizard”, Check “install from a list or specific location (advanced)”, then click “next”.

How to Install firmware
1. Download “toolkit-os” and upzip the file. Here is the link Firmware-download-tool
2. Connect your 3D printer with a computer. Double click “main.exe” to start upgrading the firmware for GTM32 control board. A window will pop up, showing the COM port for your 3D printer.
3. Click “Select” to choose the new firmware you’ve written, for instance, “GTM32.bin”.
4. Click “Upgrade” and the upgrading will start automatically.
5. When the firmware is upgrade successfully, you will see the following window. Close the window to finish the whole process.
Open Source Firmware
Quick Start
GTM32 control board is self-developped by Geeetech, compatible with Reprap G.code instructions. It is based on ARM microprocessor STM32F103VET6 to control desktop 3D printer. This control board includes 4 stepper motor drivers (driver module: 4988/2100): for X, Y, Z axis and extruder. The driver module on Z axis could connect 2 stepper motors, enabling dual rods on Z axis. To start 3D printing, the control board also supports 4 stepper motors, 1 extruder, 3 endstops, 1 heatbed and a 12V PSU (Please select a suitable PSU based on the power. We recommend 450W.)
Other expandable features for GTM32 control board include interfaces for Wi-Fi module (for remote controlling your 3D printer), filament detector (reminding you to change filament when the filament runs out or fractures), 3D touch, capacitive proximity sensor (for auto-leveling), and breaking-resuming module (resuming the unfinished print when the printer is powered on again.)
Software-related configuration.
You can modify the printing parameters on the basis of the source code. The baud rate of the GTM32 control board is 115200.
1. In the file “configuration_Select_Printer.h”, you can select the printer types.
/*****************select printer********************/
//#define BOARD_A30_MINI_S 1 //A30 printer
//#define BOARD_A30S_Pro_S 1 //A30S printer
//#define BOARD_E180_MINI_S 1 //E180 Printer
- define BOARD_M301_Pro_S 1 //M301 Printer
2. File Configuration_XXXXXX.h covers the paremeters of your printer. You can adjust the parameters manually and flash the file into the control board. It is necessary to “restore factory settings” to make the file you’ve modified to work normally.
Eg. Settings for the max temp of heatbed and extruder
- define MAX_TEMPERATURE_BED 120.0 // Hot bed temperature max
- define MAX_TEMPERATURE_NO_1 250.0 //Extrusion head maximum temperature
Eg. Settings for the moving range of each axis
- define X_MAX_POSITION 320.0
- define Y_MAX_POSITION 320.0
- define Z_MAX_POSITION 420.0 //159.0
Eg. Settings for the position of endstops
- define HOMEX MINENDSTOP
- define HOMEY MINENDSTOP
- define HOMEZ MINENDSTOP
Eg. Settings for the rotating directions of stepper motors
- define DIR_X POSITIVE
- define DIR_Y POSITIVE
- define DIR_Z POSITIVE
- define DIR_E POSITIVE
- define DIR_E1 OPPOSITE
- define DIR_E2 POSITIVE
Eg. Settings for the micro steps of motors
- define STEPS_PER_mm_FOR_X 80
- define STEPS_PER_mm_FOR_Y 80
- define STEPS_PER_mm_FOR_Z 400.000
- define STEPS_PER_mm_FOR_E 85
You can use Repetier-host, Cura, Printrun etc. software to control your 3D printer. Please follow the specific operation steps for each software.
