button, and make fine tuning with the "Z↑0.01" / "Z↓0.01" button to the extent that the distance
between nozzle and glass just fits the insertion of filler gauge. Press Next button after the tuning;
3. Calibrate the right nozzle with same operation method as the calibration of left nozzle. After the
tunning, press "OK" button to finish.
6.1.3 XY calibration
1. Click the “XYcalibrate” icon. It will prompt to confirm the material of left and right nozzle has been
loaded, and prompt to clean up the printing buildplate. After confirmation, click “Next” button to
start printing the calibration model. (If the XY offset values are known, no need to press “Next”
button, but click the “Skip” button directly and then input the X offset value and Y offset value);
2. The printer will successively print the model scale with left nozzle and right nozzle respectively.
After the completion of printing, click “Next” button. The nozzles will move to the top left corner of
the buildplate for easier reading of scales. Read the scales to obtained the X offset value and Y
offset value respectively, and click "+" / "-" button to input the numerical values.
3. X offset value should be obtained by reading the scale on horizontal direction, with the method as
below:
(1) With the model printed by left nozzle as benchmark, read the model scale printed by right
nozzle;
(2) Firstly, confirm whether the center line of right nozzle model is located on the left or right of
the center line of left nozzle model. Take "-" value if on left, and take "+" value if on right;
(3) Find out the scale line where the two models align best, count from the center line to this
scale line and take the numerical value as “N”;
(4) Input the value of "N" in the input box.
Y offset value should be obtained by reading the scale on numerical direction, with the method as below:
(1) With the model printed by left nozzle as benchmark, read the model scale printed by right nozzle;
(2) Firstly, confirm whether the center line of right nozzle model is located above or below the center
line of left nozzle model. Take "-" value if below, and take "+" value if above;
(3) Find out the scale line where the two models align best, count from the center line to this scale
line and take the numerical value as N;
(4) Input the value of "N" in the input box.
For illustration, the following figure shows the scale printed for a XY calibration. After reading, the X offset
value should be "+6", while the Y offset value should be "-6".
