The lowermost end of print head 201 contradicts, and detects pressure value.When detected pressure value meets or exceeds pressure limit,
Such as pressure sensor detect pressure be 0.2N, be more than preset pressure limit 0.1N, at this time with the pressure sensor communication
The prompting device of connection sounds the alarm or blinking light, notifies the operator axis of the centre bore of detent mechanism 100 and institute at this time
The central axis of the print head 201 of measurement is aligned.At this point, operator can select to be zeroed out the numerical value on display 302,
And will 100 position of detent mechanism at this time, that is, the position of the central axis alignment of measured print head 201 is set as zero-bit.
After completing the aforementioned steps, operator continues to move horizontally print platform 203, repeats the above process so that fixed
The gabarit of the profile and another print head to be measured of the interior limited section 152 of position mechanism 100 exactly matches, and makes prompting device same
Sample sounds the alarm or blinking light.Rotary encoder 131 has recorded the step of the horizontal movement of driving print platform 203 at this time
The angle of rotation angle value of stepper motor, and being shown by display 302, operator it is possible thereby to accurately confirm current surveyed print head and
Deviant between the print head (or being zero-bit) previously surveyed.
Although in embodiment as described above, rotary encoder 301 and the stepping for driving print platform 203 to move horizontally
Motor is connected.But in further embodiments, print platform 203 may be only capable of vertically under the driving of stepper motor
Move up and down, and print head 201 under the driving of stepper motor along horizontal motion, rotary encoder 301 and driving at this time
The stepper motor of print head 201 connects, its movement is driven when having recorded print head 201 relative to 203 horizontal movement of print platform
Stepper motor angle of rotation angle value.
