Prusa I3X A4988 pot settings

Hi guys,

I have a Geeetech prusa I3X and I recently messed up the potentiometer setting on my stepper drivers (A4988)

I have not been tinkering with the pot settings and have not been able to get it right. My prints are turning out slightly skewed.

The sensor resistor is 200 Ohms, does any one know what Vref values I should be using?

Cheers
