I asked a question on this a while ago. And now I can answer my own question.
Reason is I wanted to use 2130 drivers is because they microstep at 200 micro steps per main step. This produces almost servo like performance. The way I got them working was as follows.
On the under side of the board is a bridge that needs to be soldered. This puts the driver in stand alone mode and it behaves like a 2100 but with the microsteps. I use 16 steps in the utility and the MKS L runs flawlessly with that setting with decent slew rates and superb tracking. I am using it on a CGE conversion with 0.9 degree steppers.
