Defective A4988 Module
Posted: Tue Apr 14, 2015 2:32 pm
Hello,
I've completed my printer (Prusa i3) but one of the A4988 module is defective, I've bought from you all the electronic parts and followed instructions to the letter. After finishing my printer I've tested all motors, sensors, etc... but one motor was working jerky, vibrating and with all kind of strange noises. I've tried to use pot to adjust current for motor but it didn't solve issue so I changed A4988 step motor driver with another one and it worked like a charm. Please send me replacement for my defective A4988 module. I need only 1 module because only 1 module is not working properly.
Best Regards,
Ercan
