Calibrating

One of the things you have to do with this printer is make sure the nozzle is the right distance from the print bed each time you go to print something. I've found that if you print two things right in a row, you don't need to do much adjusting, but if you wait a few hours between prints, you need to adjust it again. Before adjusting your print bed, make sure the nozzle is in its "home" position. With the printer turned on, use the control knob, go under "Prepare", and select the "Auto Home" option. This will rest the nozzle's height and left-right position as well as moving the print bed all the way back to its starting location. You will want to make sure you do this every time before you go to calibrate the print bed's height--I forgot this step once, and had to completely recalibrate the nozzle again because the nozzle wasn't at the right height to start with. To adjust this printer you have to twist the screws on the corner of the print bed. You want a piece of regular paper to catch with a little friction between the bed and the nozzle. One of the warnings I read online was that if your nozzle is too low it can break when it runs into the print bed. This could be a very costly mistake.
