The da Vinci miniMaker uses an intuitive auto-calibration system, that adjusts the extruder and print bed accordingly to ensure, that you have the optimal prints.
I am extremely disappointed in the Xyzprinting - Da Vinci Minimaker 3d Printer. The advertising and video make it look as though this could be used by a child. Do not let the bright colors fool you! Your 3D Printer comes with no Start Up Guide. Instead it sends you to their website to watch videos. Two tech savvy adults and a 17 year old have made repeated attempts to get this up and running. We have contacted the manufacturer 4 times and have sent them pictures of our print failure. We get one layer of print and then a blob. After that, we began getting filament pouring out of the printer head. A friend of ours who works with high end printers said that this is typical of a printer head problem. This has been ongoing for three weeks. Customer Service is virtually non-existent and they certainly don't support their product. I do NOT recommend at all. Spend more and go with a different manufacturer that supports their product!
