![]() As the axes calibration involves measuring prints, you want to make sure the extruder is adjusted beforehand.įor the axes calibration, you can print a small cube, for example. ![]() Please keep in mind that calibrating the extruder should always be done before the axes because the former can affect the size of printed objects. To do this, you will have to send a few G-code commands to your printer.Īfter calibrating the extruder, it’s also important to calibrate the axes of the printer. Calibrating the axes is similar to calibrating the extruder, but requires that you actually print something. In order to calibrate the extruder, you’ll need to make sure that your 3D printer is extruding the right amount. This allows for very precise rotation control.įor a 3D printer, calibrating your stepper motors involves determining the relationships between steps and distance. For example, if one rotation is 100 steps, then the motor must rotate 50 steps in order to turn half of a rotation. On the other hand, if your first layer is peeling up from the bed, then you want to lower the Z offset.ģD printers use stepper motors, which rotate by small steps in order to move axes or the extruder a certain distance. If you see that your first layer is squished or that the nozzle digs into it, you should increase the Z offset. The goal, in a nutshell, is for your first layer to stick perfectly to the bed. This is a value that essentially tells your printer how far to move the Z-axis from the Z endstops – in other words, from the bed. You can improve your first layer by tuning the Z offset. Meanwhile, if your nozzle is too far away from the bed, your print will lack adhesion and likely fail. If your nozzle is too close to the bed, your first layer will be squished and possibly destroyed, meaning you’ll have to cancel your print. Having a good first layer is crucial to having a good final print.
