BIGTREETECH EZ2209 V1.0 Stepper Motor Driver 5PCS Stepstick Mute EZ2209 Compatible with SKR 3 EZ Manta E3 EZ 3D Printer Controller Main Board

They are standups as opposed to lying down, thus saving board real estate. They are unable to seat improperly and cause harm to the mainboard. They come with built-in heatsinks. Good little modular guys.

Easy to install device, good product for use with 3D printers, however, it might be expedient to buy 2 packages to ensure you get your printer running immediately when you get the TMC communication error on boot for one of the failed parts.

I purchased the EZ2209, and used the carrier boards that they come with to install on a BTT Octopus PRO.Overall work very well, the only problem is that sensor-less homing will NOT work with the EZ2209 when installed via the provided carrier board. The carrier board does not have the DIAG pin necessary to get sensor-less homing working. I am not sure if the EZ2209 supports sensor-less homing on a board that takes the native EZ form factor (such as the SKR EZ), but it cannot work via the carrier board - the pin is not provided.Had to purchase a couple of regular (non-EZ) 2209s for my X/Y axis drivers to get sensor-less homing working.

Went to get my custom printer running only to find out that I got a bad driver right from the get go. Now I’m stuck waiting another two days before I can get it running. Extremely disappointed by this! I had a job that needed to start in the morning. Now I have to tell my customer their parts will be late. Who tests these things!!

used these on my mercury one.1 build on my ender 5 plus worked great and the printer is silent now great upgrade
