5. Identified Issues & Root Cause Analysis

1. Thermal Derating: At currents above [2.2A], the driver enters thermal throttling after [15 min]. Cause: Undersized heatsink or insufficient PCB copper pour for heat dissipation.
2. Signal Noise Sensitivity: Spurious step pulses observed when input cable exceeds [1m] unshielded. Cause: Lack of built-in differential signaling or opto-isolation; susceptibility to EMI.
3. Inconsistent Microstepping: At 1/16 step mode, current waveform shows zero-crossing distortion. Cause: Possible low-resolution DAC or poorly tuned decay mode.
