  • Page 21 The common mistakes are the wrong select of type of board or serial port etc. 4 Get Started GT2560 is the CPU of a 3D printer, manipulating the whole process of printing. GT2560 can’t be put in use directly without uploading firmware. 1. Firmware uploading- marlin.
  • Page 22 GEEETECH #define TEMP_SENSOR_0 1 #define TEMP_SENSOR_BED 1 The two parameters are set for the type of temperature sensor respectively. They are the critical parameter to check if the sensor read temperature correctly. The printer can’t operate normally, even has potential risk (damage the device and even worse). You must modify depending on the temperature sensor you use.
  • Page 23 GEEETECH Mistakes are often made in the above two parameters. The parameters are different for different machinery. In principle, the origin should be at lower-left corner of the print platform (origin: [0, 0]), or at up-right corner (origin: [max, max]). Only in this way will the printing be correct, otherwise, the printing is the mirror image of one axis which is not what expected.
  • Page 24 REPRAP_DISCOUNT_SMART_CONTROLLER” to ensure the normal working. 5 FAQ 1. How many extruders can GT2560 support? At most 2 extruders, GT2560 supports 5 A4988 stepper motor drivers, they are X/Y/Z axis and 2 extruders. 2. What is the power required? You need to use the 12V-24V power supply, and if you are using the single extruder one, the total power is no less than 200W, if you are using the dual extruder one, the total power is no less than 2 40W.
  • Page 25 GEEETECH 3. The stepper motor on for the extruder doesn’t turn? By default in the firmware, only when the temperature of the extruder reaches 170° C can the moto r turn. www.geeetech.com Tel: +86 755 2658 4110 Fax: +86 755 2658 4074 -858...
