5Pcs TMC2208 3D Printer Stepper Motor Driver, DORHEA TMC2208 V1.2 Stepper Driver Module with Heat Sink Screwdriver for 3D Printer Controller Mother Boards Reprap Ramps1.4 MKS Prusa i3 Ender-3 Pro

I own an Anycubic i3 Mega; a very good printer, but notoriously loud from the factory. I got these 2208's to swap out. And they do in fact work quite well for the printer. Before printing anything, make sure to flash the printer with Marlin and select the right .hex file, because otherwise you'll have to swap the motor plugs, and mine wouldn't budge. For me personally, I adjusted the voltage so each one is around .8 volts (+- .02 volts) and it's worked well for me. You will have to bend the fan mount a little bit to get the fan to clear the taller heat sinks, but asides from that, a must-have mod for a printer that's got loud motors

I have to say, WOW what a difference these were! My printer no longer sounds like a 56k modem while it's printing! In fact, I am constantly having to look up to see if it's even printing still because I can't even hear it.Print quality went up quite a bit too, but I also flashed the newest marlin at the same time so that probably had some effect on that.Quick and easy to install. I just flashed an updated firmware for my anycubic so I didn't have to reverse my connectors.TIP: when setting your reference voltage, touch one of your probe's to your screwdriver and the other to the test hole furthest from the adjuster screw. This will allow you to see the voltage as you adjust it!

Awesome upgrade! Was running Arduino/RAMPS1.4 with A4988s. Had unrelated issues but decided to change the drivers for TMC2208s. They were a drop in replacement (I use them in legacy mode) and are just fantastic! The noise level is just about zero. The only sound I hear when I print is the retraction and a bit of motor "grind" when the printer homes at the start of a print job. Can easily forget it is on! It is really THAT much quieter!.Note on setting the driver vref, I tried it the way the doc says and was not making any progress. Instead I followed the instructions on a youtube video and it worked great. Connect your volt-meter ground to the board wired ground to the power supply. Connect your positive probe to a small metal screw driver using an alligator clip. Watch the volt-meter readout as you turn the screw driver. Easy. Get the correct sized screw driver and verify it with the board powered off. Practice getting the screw driver onto the "pot" without touching anything else. Then power all. Connect volt-meter and adjust pots. I started with about 0.95 per and had to adjust from there over a few hours of practice prints. You don't mind if the stepper motors get warm but they should not be too hot to hold on to. If you go too low you will get skips so warm motor is OK. Have fun!

I added one of these to my FL son Q5 Delta printer to replace the noisy extruder driver that it came with. This worked great. I had to make a change in the Marlin firmware to reverse the direction of the stepper motor but everything worked out great in the end. the heat sinks are pretty beefy and should keep everything cool in the long term and the drivers are 2208 silent steppers...and they live up to their name.

I bought these to go on an SKR 1.4 Turbo motherboard. I didn't have any experience with stepper drivers and wasn't sure what to buy as there are a lot of supported drivers available for the SKR 1.4. These had a great price for 5 and the specs matched the board so I grabbed them, they come with nice heat sinks too (see picture, blue aluminum)They are easy to install on the SKR 1.4, you have to set some jumpers and the manual for the motherboard tells yo which ones. There are two rows of pins which are color coated black on one side and blue on the other which helps you line them up correctly. If you were going to just use these as a standard a4988 driver you could probably stop at this point and you would be happy with much quieter drivers but these are uart enabled so I wanted to use those functions.On some earlier SKR (Bigtreetech) motherboards it can apparently be a big pain to get a TMC driver working, especially the 2209's I guess, which require some pin removal along with jumper settings etc. The trouble I had with these 2208's and the reason I knocked them two stars for installation was because even though the basic install is easy, in order to have them work in serial\uart mode, you have to do some soldering.From the top of the driver on the side with the blue pins, in the center, there are three very small solder pads. You must short these pads together by running a very small bead of solder between the pads. I have an excellent soldering station and many small tips... I used a small amount of flux on the pads to assist, but I still had a lot of trouble on a few of them. The solder did not want to pull between the 3 pads and stick in place. Eventually I got them all soldered up but one. So the one I couldn't solder is not in a4988 mode on my extruder while my x y z axes have the full 2208 experience which is great! You can even trim the voltage through software no multimeter required.The drivers themselves once soldered installed as 2208's no problem and work great, very tight motor control and VERY quiet. Just remember that in order to get the full experience from them, you will have to do some soldering but from what I understand it is still an easier experience than the 2209's and much better priced. YMMVSo far I love them overall.

I can't tell if my printer is running even if i'm sitting right next to it. They come with great heatsinks, absolutely dwarfs the old ones on the A4988's. Do be aware that the vref screw is on the opposite side of the board as most drivers, so double check the pins as you insert them.Only the X and Y axis on most printers are noisy in the first place, so this kit could even silence two printers and one of their extruders if that happens to be noisy.Drop-in replacement is 5/5 and dead silent, outright ghostly as the print head glides around. The UART control is available and packed with features, but I think 99% of users will get the most bang for their buck just swapping these in.. A bit complicated and for my purposes overkill, they run silent and not too hot with a single 40mm fan pointed at the board.
