HiLetgo TB6600 Stepper Motor Driver 32 Segments DC 9-40V 4.0A Suitable for 42/57/86 Type 2-Phase 4-Phase Stepper Motor

Because the manufacturer scrimped on a $0. 01 product, it's a useless driver. Technical details belowbr>In the course of testing this driver on a standard nema23 name brand stepper motor, it overheated and failed short circuit after about 2 minutes. It would have killed my stepper motor as well if my supply hadn't been current limited. br>br>save your money and get one of the many drivers priced at the going rate instead of this cut rate one. br>br>i'd ask for a replacement but based on what I discovered in testing, I know that even if it worked "properly," this driver will be substandard and unfit for purpose. br>br>technical detailsbr> In practice, with the optpisolators this manufacturer used, it's more like 1us rise time and 60us fall time, leading to at best an 8khz pulse rate if the entire rise time was required, and since very little is required, 15 khz/pulses per second is about the maximum it will do. br>br>the quality drivers use a 6n137 optocoupler designed for data transmission and is designed for up to 10Mhz and would probably work past 20.

I purchased one and found it to be satisfactory, so I purchased two more for my router build. Those two are complete duds. Using standard Nema 23 motors and a large amount of power. Right out of the gate, they're out of position. The first one works much better, but there will still be occasional misses; these are a NO GO.
