I'm using a rotary encoder and stepper motor to remotely adjust a capacitor that tunes a magnetic loop antenna. I've got that part figured out. What I don't have nailed down yet is switching between the microstepping modes for control resolution. All of the motor controllers I have looked at use dip switches to set the microstepping. This does not lend itself to having it on the control surface with the encoder wheel. Is there a controller that allows for remote changes to resolution, or do I need to remove the dip switch and build that functionality myself?
A relay bank to replace the dip switches comes to mind. Maybe even some logic-level MOSFETS or transistor switches.
"TMC" drivers from Trinamic, like the TMC2209 can be configured via serial (UART) from MCU (Arduino).

Actually, is there a reason you don;t just extend the switch by adding longer wires?
I would most likely use a rotary switch for the resolution control options I want. How that works really depends on what those switches are switching. Maybe they're ground/no ground, maybe it's 5v on or off. There are ways. I was just hoping some motor controller manufacturer had already implemented it so I don't have to.
Drivers like the Pololu DRV8825 have 3 pins, M0, M1, M2, that control microstepping, could be connected with multi pole rotary switch or connected to 3 Arduino output pins and controlled via software.

EDIT
Thanks. Their Tic T825 looks like it fits the bill.
