In general, your motor must be a 2 phase
The signal is a symmetrical meandre
on both coils. That's in full steps
. When you apply microstepping
, the meandre gradually transforms into a resemblance of a sinusoid
. The greater the microstepping
rate, the greater is the smoothness, and the resemblance of a sinusoid
may increase smoothness even further. But sometimes it may spoil it.
is shifted by quarter
period in one coild relative to the other.
is chopped into tiny pulses, so as to ensure a constant current
. The chopping technology is called a PWM

By the way, your problem might be some kind of wrong data in datagrams, which you send to the driver.
If you use a chip TMC428
, then check if you store a correct microstep wave table
into that chip.
If you drive the TMC246
driver directly from your own microprocessor
, then you must make sure the timing
of commands on your SPI
line is regular, and that the data
is correct. To eliminate the errors in creating data for microsteps
, first try to drive it in full steps
