This link [
reprap.org] is what most people start with. Once you have gone through that just figure out what you need to improve on the prints and start changing variables one at a time until you have it all dialed in.
This thing [
www.thingiverse.com] and this thing [
www.thingiverse.com] are well known prints for improving print quality. if you need to start a thread for calibration help, anyone on this forum will know what those prints should look like, which will make the process much easier for everyone involved.
This thing [
www.thingiverse.com] is my favorite calibration piece. it has a lot of different tests, and prints really quickly, so you get basically instant feedback.
Does that help? and what other questions do you have?
