BIGTREETECH DIRECT TMC2209 V1.2/V1.3 UART Stepper Motor Driver Ultra-Silent Stepsticks with Heatsink Mute 3D Printer Parts for Octopus/SKR 2/SKR V1.4 Turbo Manta M5P Motherboard 5PCS

I was skeptical how much these stepper drivers could possibly improve printer noise, but wow. Im astonished by how much of a difference these made. My only complaint with this product is that it would have been nice to get a screwdriver to use in adjusting the reference voltage. None of the ones I had on hand fit perfectly, so I couldnt tune quite as easily as I would have liked. Some competing packages come with a screwdriver for this reason.

I recently upgraded a Tronxy P802M printer when I melted one of the bed heater terminals on the crappy Melzi 2.0 board it came with. I went with the BIGTREETECH SKR V1.3, BIGTREETECH TMC2209 drivers and the BIGTREETECH TFT35 V3.0 touch screen. The instructions available arent very clear but, through the power of YouTube tutorials, I was able to get mine fully functional. I love it and Ive purchased another full setup for my second Tronxy printer.

Installed 1st set of tmc2209 on my cr-10 with an skr 1.4 turbo. Cant wait to put them in on my GTR next build starting this weekend. Oh and their customer service is awesome. Thanks for all you guys do for the community

The heat sinks were attached when I got them. Also the pins had been reinserted into the black fiber media. They work fine, but I would have rather know I was getting a used part. I have unsoldered the DIA pin to eliminate sensorless homing so Im ot returning them, just be careful when you get yours.

Lack of documentation, not beginner friendly.

I was concerned these would be knockoff tmc2209 drivers but to my surprise they are genuine bigtreetech drivers. Worked well combined with my BTT Skr v2 mainboard

Works great no complaints

Completely solved the noise problem, and even improved print quality at higher speeds

Super quiet once installed. Took over an hour to FILE THE SIDES to get them to fit next to each other. Very sloppy quality control. They were 0.6mm oversized compared to the A4988s they replaced.

I have tested 4 of the boards, not going to bother testing the 5th. Each one has failed. When the first one went up in flames, I thought I must have made a wiring error. Checked it over, redid the breadboard, tried again. A loud pop and the second one was toast. Pulled out all the extra pins, just motor voltage and VDD. Connect step pin to VDD, chip smokes. Connect step pin to ground, chip smokes. Literally just burned the chips and the money away in an hour of basic testing.
