Make sure to set the max current on the driver board to the motor limit (see below). Have a motor power supply that can deliver that current. Make sure the motor power supply voltage is within the ...

Robot that will construct 3d Building with 3d printed blocks. Construction is based on 3d Printer design. It has 3 stepper motor (2 for the base movement and 1 for the Vertical left or Vertical Right) ...

Arduinoにgrblをインストールして CNC SHEILD経由でステッピングモーターをテスト（G91X50Y50 とか）している時の様子です。CNC SHEILDは3軸までなので1軸足りない。 接続：Arduino → grbl → CNC SHIELD → Motor Driver A4988 → Stepping Motor ...

An interesting Arduino project has been published to the Instructables website showing how an Arduino CNC shield and controller has been used to create an awesome 3 axis Arduino CNC plotter. The ...

If you are planning on building a robot with DC motors then you will eventually learn that you need to control both the speed and direction of the motor if you want it to move it in a certain ...
