Stepper driver Allegro A4988: An upgraded stepper driver for the helloBEEprusa that improves the movement resolution of the stepper motors, resulting in better print quality, as well as slightly reducing the noise of the printer. We recommend either using 2XA4988 on the E0 and E1 or using 5X A4988 on all axis, other combinations are possible but not officially supported on the firmware because the resulting print quality improvement wouldn’t be significant.
Compatibility: helloBEEprusa 3D printer or any printer with RAMPS or MKS Gen motherboard
Attention: Allegro Stepper driver orientation on the motherboard is reversed compared to DRV8825
BEFORE: with Stepper driver TI DRV8825.
AFTER: with Stepper driver Allegro A4988.
