Operating manual HT500
The high-resolution 10“-TFT touchscreen mounted at the front panel enables direct operation of the
HT500.
This manual describes the initial commissioning of the 3D Printer after installation, the operation via
the RepRapOnRails operating software and the all manual operating tasks that must be performed
during normal day-today use.
RepRapOnRails Software version lists
v2.2.0 (current)
Starting the 3D Printer
There are two possible states from which to start the 3D Printer: “switched off” and in “standby”.
Either way starting the 3D Printer is a one-button-only procedure. After the boot sequence the
operating screen starts with the Print screen in IDLE mode.
Switching on
If the 3D Printer is switched off via the main
switch at the rear cover (position <0>) toggle
the switch to <I> (ON).
The 3D Printer will boot automatically.
It may take a few minutes until the touchscreen
has fully loaded the operating screen - wait
patiently without interfering.
The first screen will be the Print screen with the
(empty) print-job queue and the top-left status
message displaying Idle.
Powering up the 3D Printer.
Waking from standby
If the 3D Printer has been shut down via the
touchscreen and set into standby mode (see
section Print screen), press the wake button at
the front cover. The light ring of the button lights
up and the 3D Printer boots automatically.
Waking the 3D Printer from standby.
Graphical User Interface (GUI)
Menu selection of the RepRapOnRails operating software.
The start-up Print screen provides all basic operating functions.
The Configuration menu enables the operator to preselect temperature profiles for the extruders
and the print bed and build chamber more directly which simplifies preheating and priming according
to current needs.
Setup offers the operating wizards for guided day-to-day functions.
More advanced features such as program-independent operation of the axes can be found on the
Expert control screen which also provides direct setting of the extruder temperatures and test
extrusion.
The Log menu contains the history of machine code input and output as well as the keyboard for
direct input of operating instructions.
The following paragraphs provide detailed information of the software's operating screens and explain
the specific functions.
Additional information for the preparation of print jobs can be found in Tips and tricks and the manual
of the slicing software.

Pause function
The pause function was built in for the case that a print job needs to be interrupted and later resumed
for other reasons than “out-of-filament” (see below).
Interrupting the print with the pause function.
After tapping the [Pause Print] button, the printer keeps printing until the cache is empty. This may
take a few minutes, according to the complexity of the current g-code. Afterwards, the print bed is
lowered into its home position, the extruders are turned off and the print head moves to the
maintenance position.
Now you have access to the Expert Controls and some of the Setup functions to adjust whatever
might be necessary.
Continuing the print after pause.
To continue printing tap [Resume Print] (replaced [Pause Print]). Print bed and extruder head move to
their last position and after re-heating the extruders the print seamlessly continues.
Finishing a print job
There are two ways to finish a print job: automatic finish after completion or abortion by the operator.
After regularly completing a print job all axes are moved to their home position and the extruder
heating resistors are switched off.
If you need to abort a print job because the outcome does not meet expectations for example or
mechanical problems appear during the print, tap the [Abort Print] button. The system will then print
the last G-code information from cash and move the print table and the extruder head to their home
positions afterwards.
Either way, the 3D Printer returns to idle mode and displays a status message and a request how you
wish to continue. Simply tap the respective button on the screen to proceed.
After standstill of all drives you can remove the print bed and take off the model.

11 [Delete Printjob] Deletes the finished print job from the queue without confirmation and returns
to the Print menu.
Switching off the 3D Printer
NOTICE
Switch off the 3D Printer via the power button without turning it into standby may cause damage of
the heating elements and neighboring components due to residual heat.
The cool-down performed during shut-down ensures that the fans are only switched off after the
heating elements could shed all residual heat.
Always use this button for regular shutdown.
For switching the HT500 into standby tap the shut-down button. The system will then perform the
cool-down sequence for safety reasons before deactivating the preheating and the build chamber.
The 3D Printer is in standby mode when:
the screen turns black,
the illuminated ring of the wake button dims,
the build chamber lighting switches off.
To wake the machine from standby see Starting the 3D Printer.
For completely shutting down the 3D Printer,
perform the procedure described above and set
the main switch at the rear cover to <0> (OFF)
afterwards. The 3D Printer is now powered off
and the green status indicators of the limit
switches darken.
To reactivate the 3D Printer see Starting the 3D
Printer.
INFO
For day-to-day use, the power
supply should stay connected to
mains power (main switch in
position <I> (ON).
Emergency stop
NOTICE
The emergency stop function does not provide a cool down sequence. Do not use the emergency
stop button to abort current print jobs, as this may lead to damage of the 3D Printer due to
uncontrolled heat accumulation. Do not use the main switch as an emergency stop button. You risk
loosing or corrupting data.
Status display after triggering the emergency stop. The 3D Printer returns to IDLE state after a short
time. The emergency stop is written into the log-file.
When the emergency stop is triggered:
The microcontroller board is reset, all movement of the axes stops, lights, heaters and fans are
turned off. The status indicator displays Emergency Stop! .
After a few seconds the microcontroller returns to Idle state.
The 3D Printer now is in a safe state for troubleshooting.
For repairing any defects of the electronic equipment or major mechanical damages shut down
the 3D Printer completely:
Open the Print screen.
Shut down the 3D Printer by tapping the [Shutdown] button and switching off the main switch
(<0> position) after the shutdown procedure has been finished.
NOTICE
Before restarting or reactivating the 3D Printer:
Make sure that the axes are in no collision position.
Make sure that the reason for the emergency stop has been detected and fixed, before
resuming production.
After troubleshooting or if the reason for the emergency stop was minor and you want to continue
production:
Remove the print bed from the build chamber and replace or clean it before further use.
Restart the 3D Printer (if necessary).
Open the Print screen.
Switch on the build chamber. The 3D Printer will run the homing routine.
You can now resume normal operation.
[Configuration] screen
The Configuration menu is a new feature that enables you to preselect material-specific temperature
profiles for each extruder and, in combination, the print bed/build chamber. The latter was developed
to make preheating and leveling more precise with regard to different material settings. The
according profiles can be set up at the web interface setup menu.

temperature, both values are highlighted red.
When displayed gray, the temperature value is
either not set or currently not triggered.
If no filament profile is activated for an extruder,
the default temperature is 180 °C.
INFO
Observe that the temperature
shown in the footer is measured at
the hot end heater and may be 5 -
10 °C lower at the nozzle tip.
See section Extrusion temperature
in the knowledgebase for
information on finding the suitable
extrusion temperature.
[Setup] screen
The Setup menu displays walkthrough instructions (wizards) for different operations needed during
daily operation, initial commissioning, servicing and troubleshooting. If you choose one of the wizards,
a step-by-step guide will provide all necessary information for completing the respective task.
