I am trying to run a Nema 17 stepper with 1.7A, 12V together with an A4988 driver and an Arduino Uno.
The only power sources I have available right now are 12V, 1A and 12V, 2A. Somehow the motor is only running when the driver is connected to the 1Amp power supply. When I plug it into the 2Amp supply, nothing is happening.
The problem is I would rather use 2A since with 1A the motor is not always doing as expected. I guess this is because its current rate from the datasheet is 1.7Amp?!
Any ideas where the problem lies?
Have a great day!
Well, this is kind of embarrassing. This is the first time me dealing with steppers, and I wired the stepper the wrong way. I was frustrated and just switched the cables, now it is working flawlessly.
Nevertheless thanks for the great tips about the current limit @jremington
