3.3.2 Nozzle replacement check
Before and after detaching the nozzle and also before and after attaching the
nozzle, laser align is performed to check whether the nozzle is installed in the Z
slider shaft (nozzle YES/NO check), and to check whether its operation has
been performed correctly.
For items q, w, and e for detaching and attaching, at 10 mm below the laser
height of the nozzle, whether the nozzle is attached to the Z slider shaft is
roughly checked by Measure Once command.
For item q, whether the nozzle is attached is checked before detaching.
For items w and e, whether the nozzle is detached is checked after detaching
and before attaching.
For item r, whether or not the nozzle is correctly attached is checked as follows:
When the nozzle is attached, at 0.4 mm below the laser height of the nozzle,
the diameter of the nozzle at the tip is measured by Measure Once command.
The measured result is regarded as normal when the measured diameter
equals to the specified value. If different, it is regarded as not normal, and an
error message is displayed. When normal, to check that the nozzle is set in
the Z slider shaft, the nozzle is moved by 0.3 mm up from the laser height, and
whether the nozzle is attached is checked again by Measure Once command.
When the nozzle is not detected (Status: 64), the result is normal. For any
other statuses, an error message is displayed regarding that the nozzle is not
normally attached.
If so, possible cause is lack of grease at the O-ring in the Z slider shaft, or a
foreign matter left between the nozzle and the Z slider shaft. Apply grease or
clean out the foreign matter.
