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.

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.

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!

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'm using mine with an Anycubic Mega S. They work great. So much quieter. I waited a couple of months to install them as I wanted to be confident in the printer and my own ability. It was pretty easy. I did wind up using some other "low profile" heatsinks (spare raspberry pi kit) instead of the included ones as they were too tall for my fan arrangement. I do recommend upgrading the driver fan. I set the VRef to around .85 volts from the factory 1.1 volt. You can attach the leads of your meter with alligator clips to ground and the adjustment tool and measure and adjust the voltage at the same time as it is present on the potentiometer. The stepper motors run cool with no missed steps.Prints are as good or better. I notice a slight change in the interference pattern created by the print head motion in an otherwise smooth surface on a calibration cube. That makes sense with the step interpolation. Otherwise I can't tell a difference. It's astounding how much it changes with the same motors just using different impulses. Not sure why they don't use them to begin with other than a bit more cost. It's now a better printer. *UPDATE* I eventually switched them from Legacy mode to UART. It's tricky to solder the three little pads, but I got it done. It's definitely worth the effort if you feel comfortable performing the modification.

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 the 5-pack so I could upgrade all 4 drivers on my MKS GEN L C1.0 board and have one as a spare . Good thing I did as one of the drivers was dead. It’s annoying, but considering the cost of name brand units, it’s still a bargain.

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.
