A/B steppers skipping.

I ran my configurator with LDO-42STH48-2504AC and TMC5160T Pro V1.1.
Im running the...
TMC5160T Pro V1.0
and the LDO 42STH48-2804AH steppers.
Current 1.5
I can home just fine and the first layer seems to be doing ok but as soon as the speed ramps up the steppers skip right off the bat.

Any ideas as to how I can fix this?
