I use L6480 stepping motor control driver. and I use microstep function (resolution 1/128)
There was a problem that the motor did not move in a certain section when the motor was driven 1 step at a time with the microstep.
This picture below is the part that doesn't work when I check the section that doesn't move with the oscilloscope.
It does not move in the square marked in red.
The circuit is the same as the Eval 6480H.
Please help me How can I Move every 1 step in every section?
This is my parameter.
