Struggling to auto rotate a brush continuously

[PixLab]

I would like my brush to rotate continuously 360 deg (like a propeller if i can say that) to do something like twisted wires
something like here > https://depositphotos.com/126584858/stoc...wires.html
but I' struggling with the settings I can't get the brush to rotate continuously, I don't know what setting I should check, tried many, but felt all the way down
any suggestion?
   

here is the brush png if you want to try

There are two ways.

The first is to use a gih brush. Duplicate the image many times. Rotate each layer a little more than the previous one until there is one complete rotation.

The second method is to use a gbr brush and dynamics.

Thanks, +1 for the link, some interesting twists and good explanations,

I discovered some unexpected effect like with the triangular wave while I was tinkering ).
It does work well with a clipboard brush as well

To resume the most important are in the brush options dynamics > fade length and "repeat = sawtooth wave and in the matrix Angle crossed with Fade

again, thanks a lot, much appreciated
