TMC2209 V1.3

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

I installed these on my Anycubic mega s and low noise level and print quality is insane

Use these to run motors on peristaltic pumps for dosing my saltwater aquarium additives. Works great just using the enable, step and microstepping inputs. Love the heatsinks that come with these, wish I could find those separately to use on other components.

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.

Great motor drivers, convenient in this form for replacement. I was surprised that they came in full tape and reel, it makes keeping them around easy without worrying about bending legs or anything. They come with heatsinks.

Overall seems to be a good product. Took a star off because the header pin soldering job wasn’t great, stray solder on some of the posts that I had to remove with solder wick before I could connect them to anything. Documentation is a little rough. Used in a raspberry pi zero 2w project. I found a good library, TMC-2209-Raspberry-Pi 0.5.7, which also had good instructions for how to wire things up. To get the UART to work bidirectionally, connect RX on TMC to RX on pi directly. Then short the Pi RX to the Pi Tx via a 10k resistor. Would not work with MS1 and MS2 floating, have to tie them both to ground to use address 0. Works great with nema17s.

I haven't actually used them yet but look how well these things are packaged. This seems to be made by a company who cares about their product image. Kudos.

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.

These are excellent drivers, with headers included so there is no need to short out or cut traces for sensorless homing. I did accidentally push them into thermal shutdown, before adding a fan for active cooling - the shutdown and over-temperature warnings work as expected, and likely saved the drivers from long-term damage. If you're using these for 3D printing, save yourself the trouble and turn off StealthChop. Yes, SpreadCycle is noisier. No, the loss of accuracy and speed is not worth the reduction in noise. I ended up with some very noticeable inaccuracy on the Z-axis with StealthChop turned on, and gained a massive amount of torque in my CoreXY system by switching to SpreadCycle there as well. Overall I do think the price is a bit much, but it's not terrible all things considered so I won't knock a star off.

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!

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

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
