INSTRUCTION MANUAL Digital Light Engraver

Dealing with faults

Effective date

30.09.2013

Incorrect speed

For each mesh and each type of layer, an op-
timum quantity of light is required to expose
the screen. The amount of light is defined by
the exposure speed. Thus, incorrect speeds
lead to over or under-exposure, and subse-
quent banding.

Lens or head sys-
tem was impacted
mechanically (mis-
aligned)

An accidental collision with the head system
could cause a mechanical

misalignment,

which can only be corrected by our service
personnel.

Blocks or data
strips missing
during expo-
sure

Fibre optic cable

- cable not plugged in correctly

- cable break or damaged insulation

- cable has poorly finished ends

- check insulation in connection plug

est system with additional external fibre op-

tic cable or replace fibre optic cable with other
fibre optic system

Passes from
the single im-
aging steps
do not corre-
spond

Chip overclocked

- The maximum permissible speed and thus
the frequency for the chip was exceeded

- check 5V voltage supply to the chip (stabil-
ity)

- defective chip or card

The resolution of the system is defined by the
lens. It must not be changed. Check DLE set-
tings in Utilities

Data on edge
is missing or
exchanged

- deactivate the area by switching off the mirror
area

Machine

error mes-
sage: USB
buffer not
plotted

USB connection in-
terrupted

See above

Machine
stops after 1st
exposure
pass and
gives an error
message

Incorrect data for-
mat

User selected a file that has an unsupported
data format or is in a compressed format (see
manual)

WCB defective

Replace WCB

Exposure
starts at the
wrong posi-
tion

DLE settings have
been modified

Under UTILITIES – DLE settings the work po-
sition has been defined. This is the zero posi-
tion for all start offsets (see manual)

Screen size incor-
rect

When both the X and Y values in the screen
definition are not identical, the system starts
the exposure at the corresponding next (2

)

smaller size
(see manual)

Units have been
changed

- in the programme click the “Options” tab and
select “Units”. Here you can change the units
and resolution

- changing both can lead to this phenomenon

Slight offset in Background appli-
