On my side this was solved with a 10A power supply and the TLE5206. With a 15kg sled at 8°.
With the TLE it was the first time to see a motor actually stall. Before it was just killing the original shield chips and/or the 5A power supply. I can’t calculate it, but i’m testing and observing for some time.
