![]() ![]() Make a pencil drawing of how everything is connected and post a copy of the drawing. It is a total of four slots, can drive four A4988 stepper motor. This expansion board as a driver expansion board, can be used for engraving machines, 3D printers. Why not make life easier for yourself and start with a single motor like I suggested in Reply #1 A4988 Driver CNC Shield Expansion Board for Arduino V3 Engraver 3D Printer FZ1350. I think that code should work - so there must be a wiring problem AccelStepper Zaxis(1, 46, 48) // pin 46 = step, pin 48 = directionĪccelStepper Xaxis(1, 54, 55) // pin 54 = step, pin 55 = directionĪccelStepper Yaxis(1, 60, 61) // pin 60 = step, pin 61 = directionĪccelStepper Zaxis(1, 46, 48) // pin 46 = step, pin 48 = direction AccelStepper Yaxis(1, 60, 61) // pin 60 = step, pin 61 = direction AccelStepper Xaxis(1, 54, 55) // pin 54 = step, pin 55 = direction Please post your code properly using code tags so it is easy to read and easy to copy to an editor - like this #include #define TEMP_1_PIN 14 // ANALOG NUMBERING There are pin mappings to Atmega8 and Atmega 168/328 as well. #define TEMP_0_PIN 13 // ANALOG NUMBERING A diagram showing the correspondence between the pins on an Arduino board and those of the ATmega2560 microcontroller. Im not sure how though, can someone help me understand how as this is for a college project that I volunteered for but I'm really struggling! I'm wanting to manipulate the code so that I can control 3 stepper motors at different speeds independently possibly using the tSpeed function of the stepper library? It contains everything needed to support the. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. No more QUEUE state.Hi there, I have some code (below) that is basically to test that all motors/extruder/heated bed work on a 3d printer set-up. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560.
