I performed all the above actions,
removed the pin brackets, bent the contacts on TMS 2209
posting a photo of the board.

Hi, Please always start a new topic. While it might seem the exact same if it was, the solution should also work. Let’s take a look at your individual situation.

What firmware are you using, since none of ours only has three drivers? What are you using this for? Why not use our firmware?

Your power needs to go to the MOTOR pins as well.
