    Estos artículos son de buena calidad. El pcb es de buena calidad, el montaje de componentes electrónicos bien hecho. El kit está completo, no falta nada, incluso se proporcionan los puentes para ajustar la velocidad de los motores de paso. Esta es una muy buena relación calidad precio.

    This CNC GBRL based driver board kit can control up to 3 stepper motors with the electrical components included. The main board has convenient pin headers to connect stepper motor leads and as many of the limit or other switches you might choose to adopt for your project. The jumpers seen under the stepper driver board location are for the adjustment to configure the stepper board. Default is often good enough. The use a of a Nano form of processor board makes it easy for me to swap with another one if I was testing a new firmware but wanted to keep old one I was comfortable with. Also I can decide to only place the quantity of steppers driver modules as needed. So if I only had one axis with a motor. I could save the other driver boards as spares. The plug fashion of module also allows debugging by swapping module components to see if fault moved with a particular module.

    On my CNC shield V4, the STEP and DIR was not corresponding between the pin layout from the Android Nano and the step driver board. After switching both pin the bor start to work. Edit cpu_map.h file like below: #define X_STEP_BIT 5 // Uno Digital Pin 2 #define Y_STEP_BIT 6 // Uno Digital Pin 3 #define Z_STEP_BIT 7 // Uno Digital Pin 4 #define X_DIRECTION_BIT 2 // Uno Digital Pin 5 #define Y_DIRECTION_BIT 3 // Uno Digital Pin 6 #define Z_DIRECTION_BIT 4 // Uno Digital Pin 7 P/s: this fix apply for grbl 1.1 version, edit map pin in config.h file at the older version
