The build chamber can then be reactivated via
the
[Print]
menue.
Detailed information are provided in the
Operating manual
.
The emergency stop button in the top-right
corner of the GUI will immediately stop all
movement and set the 3D Printer in a safe state
for troubleshooting.
Operator qualification
Operating and service personnel must be familiar with the information provided in the manual.
Special training and qualification are not required for operating the 3D Printer. Works on the electrical
equipment and connections of the 3D Printer require profound knowledge of electrics and electronics.
Personal protective equipment
During normal operation it is not necessary to wear special protective gear. Some tasks however
should not be performed without taking protective measures. Situations that require protective
equipment are specially indicated. It is the owner's obligation to provide adequate protective
equipment.
Product reliability
False handling of components can lead to loss of production due to property damage; therefore we
strongly recommend following the information given in this manual.
Extruder nozzles
The brazen extruder nozzles are sensitive to heat treatment and mechanical strain.
If the nozzles or extruder barrels are clogged by congealed material, reheating during the normal
production flow is utterly sufficient to clear them in most cases.
In case you want to change the material type or clogging is effected by foreign particles (i.e. dust
grains dragged along with the filament), it is necessary to remove congealed material from the
nozzles. The corresponding description can be found in the
cleaning recommendation
.
NOTICE
Do not use mechanical tools or open flames to remelt or remove residues in the nozzles. Overheating
may induce easing of tensions and deformation. The nozzle is then no longer usable for printing.
Structural and functional description
The following paragraphs name and explain all components of the HT500 to give you an exact
overview. The terms are used consistently throughout this manual and will help you identifying any
part you may wish to find or
order as a spare part
