BIGTREETECH DIRECT TMC2209 V1.2/V1.3 Stepper Motor Driver Silent UART Stepsticks VS TMC2100 TMC2130 for SKR 2/ SKR V1.4 Turbo Manta M4P Manta M5P/M8P 3D Printer Motherboard (Pack of 4pcs)

Pretty darn quiet and work well. Would have preferred a version without the pins already attached, but I understand that most people want the pins on them, so there is that. Good that they include the heatsinks as the can get toasty.

I ordered 5 of these total to upgrade the stock drivers in my Anycubic I3 Mega (previously upgraded with the Mega S upgrade kit). Now the machine is so quiet that when I started it printing, I thought the extruder wasnt working at all. The ONLY noise coming from it now is the fans, and I have upgrades in the works for those too, as well as some MOSFETS for safer power to the hotbed and heater.

Worked perfectly for my Tenlog Printer. I had a fan fail and the heat smoked the 2209 chip for Extruder E1. Ordered the 4 pack and attached 2 of the packaged heatsinks for extra cooling and I was off to the races in under 20 minutes.

Got these as spares for my btt skr 1.4 turbo boards.. have been running my printers pretty hard lately and like spares on hand, zero failures to date though so these will probably just sit on a shelf forever.

This stepper driver was to replace one on a functioning 3D printer. The existing one was a 8825 for the bed axis. I was getting overshoot at high speeds, and thought a larger motor with a driver that could handle more current would help. So far, I replaced the driver, but not the motor yet. I had to change a jumper setting on the board, so the steps would match my existing setup, as the 8825 used the jumpers in a different config. It works well, and made that axis of the printer much quieter. However, it actually doesnt hold as well as the 8825 did. I tried adjusting the current, but would still lose steps at high speeds, where the 8825 could still hold. I had to adjust my jerk speed down some for this driver, and it is smooth and quiet, but was hoping for more on the holding power. Maybe with a new motor, it will do better. If youre looking for a cheap upgrade to really cut down the noise, then this is for you. I wasnt concerned about noise, just looking for something that could handle more current.

Despite the driver being advertised as SPI working mode, you cannot actually drive the motor via the SPI interface. This is because while the SPI_MODE pin is high, SD_MODE is also tied high to its neighbor pin, VCC_IO. You configure the driver over SPI, but need to drive it exclusively with step/dir pins. This was not reflected in the item description.

Power in a few Nema 17 drives, these motor drivers do the job way better than anything else I have used. The heatsinks stay cool to the touch when running. My other drivers burned my hands after running for a minute or two. They are also night and day quieter than most drivers. I will be buying more for future projects.

swapped my a4988 drivers out for two of these and plugged them in and put a jumper between the en/gnd on my cnc shield and they worked right away! the vref came set perfect for my 1.5a steppers and they make ZERO sound!

I ordered UART mode to avoid having to do additional soldering, but I still received the standalone version. The soldering pads are very tiny. Hopefully my hands will be steady enough to solder them without breaking it. I understand mix ups happen, but this is annoying.

It’s probably not the drivers fault, but the BTT Octopus board wouldn’t acknowledge these steppers. I give up on BTT and Biqu. Returned everything and changing brands
