Hi,
I'm wondering how to setup 1/16 microstep for the driver. Is it just connect VMOT to all MS pins and all pins to GND?

All MS(0,1,2) pins high for 1/16th micro-stepping yes, assuming you have a real Stepstick with A4988 - not A4984 which cannot do more than 1/8th.

BUT NOT TO VMOT !!! eye popping smiley

The correct high level for logic inputs is VDD.


Most of my technical comments should be correct, but is THIS one ?
Anyway, as a rule of thumb, always double check what people write.

You have most likely destroyed this stepper controller. the micro stepping pins cant take > 5v.
