Hi All I am attempting to get 3 stepper motors working for a project to make a motion control camera setup for use with Dragonframe animation software.
I ordered this kit from Amazon: Arduino UNO kit
I have a 12v 5a power supply, with a small adapter on the end like this: Connector
..to connect to the CNC shield.
I have successfully loaded the Dragonframe DFMoco image onto the Arduino and Dragonfra recognises the board as such.
My problem is in driving the motors.
I get some buzzing from a single connected stepper motor, and occasionally is will turn (one way only for some reason).
The moment I connect two or more motors there is no movement, just some buzzing.
I have tried adjusting the potentiometers on the stepper drivers to no avail.
I have a multimeter.
What I am thinking now is that the small cable adapter (above) I have between the power supply and the CNC shield is limiting the power getting to the board - is this likely/a possibility?
Many thanks for your help
