STEPPER DRIVER

[Tulip]

I have 2 stepper motors Nema 17 motor:

Do you know a good cheap driver for these motors?

I tried with pololu A4988 driver, but I don't like it. It doesn't have enough Output Current and I broke it.

Thanks

Selection Recommendations:
If you need industrial-grade high current/high torque, choose the TB6600 (but consider size and heat dissipation).
If you need a simple replacement and are cost-conscious, choose the DRV8825: https://www.ti.com/lit/ds/symlink/drv8825.pdf (highest value, directly replaces the A4988 socket).
If you need A4988 pin compatibility and quiet operation, choose the TMC2208-LA: https://www.avaq.com/chip/tmc2208-la (note the wiring configuration; some versions require flying leads).

Thanks for the suggestions. I’d probably lean toward the TB6600 if the motors really need more current than the A4988 can comfortably provide. The DRV8825 is also an interesting option if keeping the same general form factor and pinout is important.

I’d definitely check the motor’s rated current and set the driver’s current limit accordingly before running it, since overheating the motor or driver can be just as problematic as not having enough current.
