BIGTREETECH TMC2209 V1.3 Stepper Motor Driver, 2.8A Ultra Silent Stepsticks Supports UART/Step/DIR Mode for Octopus V1.1/Octopus Pro/Manta M4P/M5P/M8P/SKR V1.4 Turbo/SKR 3 Control Board 6Pcs

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

Bamm, just like that brought my Artillery S2 back to printing. I have to say after trying several other replacements, this one is dead silent like the original driver. Thank you!Edit:Awwww for some reason the step motor on my printer now runs backward. Boo. I think it's still a five star for someone else. I don't want to learn how to edit my firmware for this.

Works great!

I'd been working on a stepper arduino controller, I tried several drivers.- first was the L289N - wayyyyyy too much current, motor and controller too hot to touch, 60 Watts!- second was the DRV8825 - much better, but there was still quite a bit of noise and the motor rumbled around on the table- third was TMC2209 - This hit the sweet spot, motor is inaudible and heat is very much under control

A breeze to work with... I purchased a different stepper motor controller, and well......let's say after HOURS of diagnosing why my motor was just buzzing... even breadboarded a 1Hz astable multivibrator circuit to watch the drive pattern, and verifying the motor was wired correctly. All "appeared" to be right, but yet, the motor just buzzed at me. Decided to give this driver a try -- worked right "out of the box" -- connected to my triggering circuit (not the astable multivibrator) and watched the motor spin like expected. Don't go cheap or off-brand -- save yourself the headache... BUY THIS DRIVER!Now, I can refocus my efforts on the real task, not figuring out what the driver is doing.

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.

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.
