Hi,
I've just about finished my Prusa i3 build and the Z axis steppers seem to need a little more juice when they did in my Prusa i1.
In the past I just slowly turned the pot until it no longer had issues then a little more for good luck, however I've seen a few posts and guides on using the vref to calculate a good starting point.
The trouble is I'm running a few different drivers, I've got an official Pololu A4988 with the vref, 2 stepstick 1/16 without the vref and a stepstick A4984 without vref (the one controlling the Z axis).
Is there any calculator or guide I can follow for this motley collection? Or is my old method the best with this variety?
Thanks
