Somewhere I thought I read a thread from a more experienced member about optimizing the print speeds to get good prints.

i can't find it.

I think I am need of some fine tuning. I am getting some weird ripples in the edges of my prints and most recently, when moved the nozzle to 0 after a print it crashed into the bed. This lead me to believe I may be skipping some steps on the z axis.

What are people using for feed rates and accelerate numbers? Can I turn up the stepper driver to compensate for it driving two motors? They are not warm at all.
