S30 is much higher than normal, and H50 is much lower than is typically viable for reliable stall detection. The Trinamic datasheet for the stepper drivers states that 1 rev per second is typically the lowest speed at which an impending stall can be detected, which is why H defaults to 200 in the M915 command. I suggest you start by leaving H at the default value of 200, which should allow you to use lower S values.
