I am not an expert with these types of motor controllers. I first bought a Synthetos shield but was noisy. When I went to build a second device, they were out of stock so I ended up buying a CNC shield off Amazon with some other motor drivers.. It was a disaster, never worked right, was noisy when it worked, was missing steps, caught fire once, ended up shorting out and blowing up my laptop. Then I bought a set of these. I had to remove the two extra pins for diagnostics, because they were in the way of the CNC shield’s own pins. This was easily achieved by heating up the solder joints, and then pulling out the pins. With that being said, I plugged it directly into the CNC shield, and it was instantly working correctly, with no missed steps, and very quietly.. much quieter than the other motor controllers and much quieter than the G shield. I highly recommend these motor drivers

These are excellent drivers, with headers included so there is no need to short out or cut traces for sensorless homing. I did accidentally push them into thermal shutdown, before adding a fan for active cooling - the shutdown and over-temperature warnings work as expected, and likely saved the drivers from long-term damage. If you're using these for 3D printing, save yourself the trouble and turn off StealthChop. Yes, SpreadCycle is noisier. No, the loss of accuracy and speed is not worth the reduction in noise. I ended up with some very noticeable inaccuracy on the Z-axis with StealthChop turned on, and gained a massive amount of torque in my CoreXY system by switching to SpreadCycle there as well. Overall I do think the price is a bit much, but it's not terrible all things considered so I won't knock a star off.

Used these to upgrade my Anycubic Mega X. Easy to change out and configure following what others have done on YouTube. Reversing the board connectors are the most challenging part, but if you take your time and be cautious it’s not that difficult. My printer is dead silent now, I just can’t believe why these wouldn’t be stock parts right from the start! It made a good printer into a great printer!

Super smooth stepper movement and so much quieter than the stock ones in an anycubic chiron. (Went from 68 decible noise during printing down to 42 decible!.. the silence is golden!!!) Also have been able to increase my print speed by 20mm/s.. only pain was to set the vref (i didnt install in uart mode) but that was my choice to install that way.. should have upgraded to these on day 1

Use these to run motors on peristaltic pumps for dosing my saltwater aquarium additives. Works great just using the enable, step and microstepping inputs. Love the heatsinks that come with these, wish I could find those separately to use on other components.
