It is important to check that the print head can move freely in all 3 axes: X, Y and Z. This procedure makes sure that all packaging material has been removed before first use. First power up the printer, then use the manual move function to move the print head in all three axes:
CAUTION: Always move the Z axis first to ensure that bed is away from the extruder nozzles, and does not collide during an X/Y move. Collisions between the extruder nozzles and the bed may damage both.
CAUTION: Observe each X/Y axis movement. In these axes, it is possible to drive the extruders too far away from the "Home" position (shown in the picture below) into the printer frame. Avoid this. Excessive collisions will damage the printer.
CAUTION: Observe each Z axis movement. In this axis, it is possible to drive the bed too high (into the extruder nozzles) or too low (into the motor coupling). Avoid this. Excessive collisions will damage the printer.
