Hi, to all I have started a CNC project using UNO R3 and Adafruit Shield L293D.
Here is my equipment:
Arduino UNO R3
Adafruit shield Motor L293D
Stepper Motor NEMA 17, 5 - 12 Vdc
Stepper Motor 0404A 24.2 V dc
External PWR supply 24 Vdc
Universal Gcode Sender 1.0.9
When I used the arduino multiple stepper testing from the arduino library, the 2 motors is working fine. But when I used the Universal Gcode Sender, motor is not responding at all. Everything is working fine from Arduino to Grbl.
Please see attached file.
