100% Brand New & High Quality

• 1. Combine 2560 and ramps1.4 on one board to solve the problem of Ramps1.4 combination interface is cumbersome and easy to malfunction;
  2. Replaceable motor drive, support 4988 drive, 8825 drive, TMC2100 drive;
  3. The circuit board adopts high-quality 4-layer board, and it is specially optimized for heat dissipation;
  4. Adopt high-quality MOSFET tube for better heat dissipation;
  5. A special power chip is used to support 12V-24V power input to solve the heating problem of the Ramps voltage conversion chip;
  6.24V input can be accepted, and the current of the hot bed can be reduced to 1/4 under the same system power, effectively solving the problem of heating of the MOS tube of the hot bed;
  7.The firmware can use the open source firmware Marlin, the configuration is exactly the same as ramps1.4, and it can directly replace Ramps1.4;
  8. Can be directly connected to Ramps1.4, 2004LCD control board and 12864LCD control board;
  9. The motor pulse and direction output ports are reserved to facilitate the external connection of large current (such as 2A, 5A) motor drive circuit;
  10. Retain the Servos, AUX-1, AUX-2 interfaces on Ramps1.4, and provide 3-5V output and 3 12V output interfaces;
  11. Fully consider the stability, heat dissipation and ease of use issues, after continuous printing reliability test. The same, can directly replace Ramps1.4.

  pay attention:
  1. Please make sure that the positive and negative poles are properly connected before powering on;
  2. Please do not plug and unplug the motor and drive when it is powered on, it is easy to cause the drive to burn out; also do not adjust the current while the motor is running. The correct method is: first disconnect the power supply, unplug the motor, and then power on again, adjust the potentiometer, measure the voltage on the potentiometer until the measured voltage is the same as expected. Do not plug in the reverse drive, otherwise the drive will be burned, or even the motherboard!
