Using Pololu TB67S249FTG

This stepper motor driver has not been tested but should work.

You should not mix these drivers with any other type.

Jumpers

Put the (3) SPI/MS jumpers on the MS Side. That forces them to send Vcc signals to the drivers. This sets 16x microstepping mode. No other values can be used.

Set the TMC5160 jumper on the TMC5160 (low) side to keep the motor energized when that axis is not moving.

Set the Vcc jumper to the 3.3v side.

Machine Definition File

You should have a #define USE_STEPSTICK in your machine definition file. This will force the DMODE2 pin to Vcc. This will put the driver in 1/8 step mode. It might be possible to add a mode to put it in 1/16th mode in the future.
