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 little guys work good. Prices seemed to have jumped a little.

So I have to say right out of the gate that Biqu was great about replacing the motherboard on my printer when it failed. The failure also caused the print head/hotend to gum up real bad and it was pretty well ruined, and they replaced that as well.When swapping out the stepper motor drivers I likely ruined one unless it got damaged when the motherboard failed. Either way, I ordered these on my own to replace the ones that came with the original motherboard.THEY WORK GREAT! They literally are plug and play and my stepper motors are super silent. If you want to upgrade or just replace failed stepper motor drivers, these are an excellent choice.

I really like these BTT 2209's. They are a bit less expensive on Amazon than most 3D printing stores but are the exact same product you would buy.

This stepper driver was to replace one on a functioning 3D printer. The existing one was a 8825 for the bed axis. I was getting overshoot at high speeds, and thought a larger motor with a driver that could handle more current would help. So far, I replaced the driver, but not the motor yet. I had to change a jumper setting on the board, so the steps would match my existing setup, as the 8825 used the jumpers in a different config. It works well, and made that axis of the printer much quieter. However, it actually doesn't hold as well as the 8825 did. I tried adjusting the current, but would still lose steps at high speeds, where the 8825 could still hold. I had to adjust my jerk speed down some for this driver, and it is smooth and quiet, but was hoping for more on the holding power. Maybe with a new motor, it will do better. If you're looking for a cheap upgrade to really cut down the noise, then this is for you. I wasn't concerned about noise, just looking for something that could handle more current.

A great choice for a stepper motor driver. They reduce printer noise well and you can use sensorless homing with them.

Got these drivers on time, and they work perfectly with SKR 1.4 turbo and ender 3.

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

Funcionaron muy bien para una two trees bluer

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!

Ran in UART for my voron on an octopus. Loves it.

They work as direct replacement on my 3D printer but require better instructions to utilize the special features
