Hi there. I’ve been making a tiny CNC machine based on different tutorials for arduino. I have Arduino Uno original Italian board. with motor shield, 2 steppers (for DVD drive) and a servo and a DC adapter (12V, 800 mA). When I use Arduino IDE software, it works fine, 2 step motors work with adafruit motorshield library and move fast. Then I upload GRBL library to the board. I noticed it can communicate with the board just with 115200 (not 9600) serial. And then I installed universal Gcode sender or Processing software. I set the serial to 115200 and it connects to the board (the message Grbl 0.9j [’$’ for Help] appears).
But it can’t move the stepper motors when I upload gcode file or use the x, y buttons manually.
- I noticed a small sound comes from the steppers when I press x or y buttons manually and the led on the board blinks by pressing the buttons, but the steppers don’t move.
- I don’t think the voltage and current is the problem because Arduino IDE can move the steppers fast. And I used another adaptor with higher current output, too.
I would appreciate if you help me with this? I think everything seems OK but the steppers don’t work.
