QA Table
Using a torque gage, measure the torque when the nozzle starts turning.
The nozzle (which has passed the inspection) must not be turned by a torque of 0.020 N.m {0.20 kgf.cm} or less.
A possible cause of the trouble is an inadequately machined nozzle holding section of the Z-slider shaft.
A remedy of the first choice is to replace the part.
Prevents the nozzle from being misaligned with respect to the Z-slider shaft when the θ-axis turns.
– Poor placement accuracy (θ deviation)
– Nozzle replacement error
– Damaged nozzle

(2) Lack of clamping force by the set screw
Remedial procedures are:
(1) See QA Table.
(2) Retighten the set screw.
