Problem
Possible Cause
Solutions
Laser pauses during a
job.
Random Pausing or
other button pushes
(panel led lights green
randomly).
The laser stops
movement during a job
and displays a “Paused”
message on the touch
panel and/or the Pause
button in RetinaEngrave
is grayed out, without the
user having commanded
a pause.
This occurs due to the
sensitivity of the front
capacitive touch panel
combined with
ElectroMagnetic
Interference (EMI) caused
by a poor connection to the
tube electrodes.
Tests:
1.
Unplug the short USB cable going to
the panel— this should fix the issue
and the job should complete normally.
You can run any job as normal with the
panel disconnected using the
computer to control the laser.
2.
Reconnect the panel and open the
lid and run the job. The laser will not
fire with the lid open. The job should
complete normally without ever
pausing. This indicates a bad ground
connection; ground is located on the
left side of the laser tube (nearest the
emission aperture).
Resolution:
1.
Clean the electrode and rewrap the
ground wire on the laser tube (see
Appendix F – Tube replacement)
2.
Shifting of the connection during
shipping can sometimes cause a loose
connection to the ground wire. The
voltage on this wire is less than 0.1V
and it must make tight contact with the
electrode or else there can be
unpredictable EMI behavior. Remove
the wire, sand the surface of the
electrode and rewrap the wire on the
post. We recommend a few layers of
teflon tape to hold down the wire to the
post. The post is very delicate and we
do not recommend attempting to solder
to it as solder doesn’t hold and we also
don’t recommend crimping to it to
prevent breakage of the surrounding
glass. Wrapping the wire + wrapping
with teflon tape to hold it down is the
best way to install it.
3.
It is not necessary to insulate this
low voltage wire. Previously, tubes
were wrapped and insulated on both
sides but only the Red high voltage
wire MUST be insulated.
