Obligatory I’m new at this. Ok, let’s go:
I have a setup using the SparkFun Red Board, the Schmaltz Easy Driver, a 400 step motor, and a variable 0-30 V power supply that can deliver up to 2A.
Main Motor Specs:
2 Phase, 3.06 V max, 1.7 A/phase
Easy Driver Specs:
Up to 30 V load supply, 750-850 mA output current
Now, I recognize that the motor current requirement is above what the Easy Driver can deliver, but it was driving the motor when I first started using the setup (I inherited this setup).
I have since tried using it together and while the Easy Driver board lights up and delivers signal to the motor (as seen on a scope reading), the voltage it delivers is very low (like an amplitude of 189 mV).
Does anyone have insight into what happened to the set up? I have turned up the voltage on the power supply to 20 V +, but that’s not doing anything. Why would the voltage delivered be so low?
Also, the Easy Driver has a potentiometer for adjusting the current, but that hasn’t seemed to make a difference, although I’m open to any suggestions regarding how to test that.
