PLA extrusion not consistent

[tjnamtiw]

Have you adjusted the VREF of the extruder motor control Stepstick?

fjnamtiw, I actually don't know to what you're referring to. How do I go about doing that and what does it do? I have put in a new bolt and feeding tube. I do have to mention that I bought it used and that the 3d printed parts for the extruder don't look in the best shape. I have been able to get some good prints on abs although I have had the same problem once in a while
