    Hi, I did as you advised, and it works ok. The problem I encountered is when I want to turn off the engine, I send a high state to the EN input. This causes the motor power cables (which are connected to the controller) to melt. The problem does not occur when the engine is running.
    I wonder if the problem lies with the cables or should I turn off the engine / connect something differently?

Topic summary

The discussion revolves around issues faced while operating NEMA 17 stepper motors (0.51 Nm) using an A4988 driver and Arduino. Users report problems such as motor squeaking, vibrations, and insufficient speed. Suggestions include using an external power supply to improve current efficiency, adjusting the current limit on the A4988 driver, and implementing acceleration and deceleration (ramping) techniques to prevent lost steps. Some users also explore the possibility of using DRV8825 drivers as an alternative, citing their advantages in handling higher currents and microstepping capabilities. Proper wiring, voltage settings, and driver configurations are emphasized as critical for successful motor operation.
