11 You're Done!

You're done with installation! Verify the functionality of the printer prior to your first test print.

Connect the power cable.

Power on your 3D printer.

Check the heated bed temperature in the Graphical LCD Controller on the TAZ.

If a 0 or zero is displayed the heated bed thermistor is not connected properly. When connected properly the heated bed should display an ambient temperature of 10°C - 30°C.

Start a test print and carefully observe the auto bed-leveling sequence.

During the auto bed-leveling sequence, the nozzle should lightly touch down on each metal corner of the bed.

Perform test print.
