2PCS TMC2208 V1.2 3D Printer Stepper Motor Driver, Upgrade TMC2208 Stepper Driver Module with Heat Sink Screwdriver for 3D Printer Controller Mother Boards Reprap MKS Prusa i3 Ender-3 Pro

Absolutely the best thing I did for my Anycubic i3 mega s printer. They work great and holy moly is it quiet.

Thanks these actually work lol. Although I cannot for the life of me understand why the UART can't just control the entire thing. It's just an add on for tweaking.But two other types I ordered were DOA so I appreciate these.

Works great on a MKS gen L board running Marlin 2.x.x.These are setup as standalone drivers out of the box. Make sure to disconnect steppers, power up board and tune voltage first.Pots were decent, a little overshoot when adjusting so go slowly.Would buy these again.

I upgraded my DIY motorized blinds from DRV8825 to the TMC2208 and I am amazed at how much quieter these are than the DRV's. I mean, it is night and day. And they are almost 100% pin compatible. There is no sleep or reset pin on these but the step, direction, enable, microstep, motor,and voltage pins are all the same. One limitation though, the only way to go into full-step mode is to use them in UART, which I didn't want to go to the trouble to do so I am running them in half-step mode and they are still just as quiet. Just apply your VCC to the MS1 pin to get the 1/2 step setup.Also, they probably wouldn't have been a problem but it appeared to me that the solder joints on the top of the pins got too close to the heatsink for my comfort. So I trimmed them with my micro-cutters before applying the heat-sink to give extra clearance, just in case. And you will need the heatsinks. These do get much hotter than the DRV's.

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.

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!

These come in their own individual anti-static baggie with a screwdriver and a large aluminum heatsink that you have to stick on.They work great on my Anycubic Mega S 3D Printer and plug directly in where the old ones go, but you will have to swap the Motor 1 and Motor 2 phases on the motor connector that connects to them if you are doing something similar.The heat sink also sticks up higher than anything that it might replace, so you may have to modify cooling fan brackets and similar depending on what type of equipment you are installing these into.
