I got a prusa i3 acrylic with ramps 1.4 board. One of the A4988 is not working. I first thought it was the motor but when I hooked up motor to another driver it worked and when I put a different motor on the broken A4988 it didn't work. Please send me a replacement. Thank you.

I checked everything and there were only 4 x A4988.

Are you sure? We have 5 X A4988 for ramps1.4.
This is the picture of ramps1.4

Oh, sorry. 4 is enough, for 5 motors (2 Z motors are parallel, so they need only 1 A4988).
Could you please tell me where you bought the printer? Please send me your order number.
