Anet A8

Calibration is normally not needed as this is carried out by the manufacturer and stored in the factory installed firmware. Information on printer calibration:

Sometimes the center of the bed is not the actual center. When printing large prints, the skirt, brim or the object itself is printed outside the heated bed. For bed center offset calibration please read:

The fabric reinforced belts that come with the printer are OK, to a point. There are loads of belt tensioners and frame reinforcement modifications - use some, I particularly like the Y tensioner frame, this one, and for X, this one. Speaking from bitter experience, AVOID steel wire reinforced belts, yeah they don't stretch, but the wires DO BREAK because the GT2 sprockets are so small, then they stretch and cause no end of problems. Mine broke and there were fine wires sticking out of the smooth back. If your belts stretch you will finish up with non circular prints and not in the direction you expect - which makes fault finding difficult. Tension the belts with care and absolutely better loose than too tight - If your prints aren't perfectly circular:

  1. Ordered List Item Very gradually tighten and run a test print between each change.
  2. Ordered List Item Change the belt.
