Test Before Print
Click “Motion” → “Auto Home” to execute the homing (home position: on the
left side of the bed).
Choose “Temperature” → “Preheat PLA”. Observe the temperature of nozzle
and bed.
Choose “Motion” → “Disable Stepper”. After unlocking the motor, we move it to
the center of the X axis.
We observe and judge whether the two ends of X axis get the same reading on the
scale mark bars (on the left and right sides). (You can skip this step if your printer
already has the same reading on the two sides.) Now,start your calibration and
rotate the couplings simultaneously till the two ends of X axis get the same reading.
-Movement test
-Preheat hotend and heated bed

Choose “Configuration” → “Calibrate Z”. Choose “Yes”.
After you finish the homing, the Z axis height of the nozzle displays on the LCD
in real time. Now turn down the height of the nozzle. Place the A4 paper
between the nozzle and the glass platform. After that, you can push and pull
this paper till you can fell the slight friction. Otherwise, you need to
recalibrate Z axis.
