4. ACTIVITIES CONNECTED WITH PRINTING MATERIAL
3DGence DOUBLE P255 printer is equipped with the diagnostic system of the extrusion system. The diagnostic system
significantly facilitates printing with a variety of materials. The system consists of a filament sensor (fig. 38), bowden tube and
extruders whose correct operation is monitored by encoders.
Among other things, the system makes it possible to:
•
choose the temperature of heating elements in a semi-automatic manner, depending on type of material;
•
inform the user about problems and errors;
•
detect that the material has finished;
•
monitor the filament flow.
The system designated as "Flow rate monitor" is automatic and invisible for the user. However, the system makes it possible
to determine the threshold value of the flow difference. The material flow difference is understood as the difference between
the amount of material required by the control code and the amount of material detected by magnetic encoders measuring
actual filament movement. The activation threshold expressed as a percentage determines the specific value of the material
flow difference. If this value is exceeded, the printer will stop working. At this time, the user can solve the problem connected
with filament extrusion by unloading and reloading the material. The threshold value of "Flow rate monitor" function set to
100% corresponds to the total conformity of extrusion parameters. 1% corresponds to the maximum error required to ensure
continuity of printing process (however, it does not guarantee positive effects). If the value is set to 0%, the system is
deactivated.
The default threshold setting of 70% ensures quality control of the extrusion process at the manufacturer's specification level.
When using materials that may cause the interference of readouts (for example, highly flexible materials, materials from other
manufacturers or materials with large diameter variations), it may be necessary to reduce the default threshold value or even
set the value to 0% in order to deactivate the system.
To change the error notification threshold:
1. Go to
MENU → Advanced → Flow rate monitor (fig. 25).
2. Use the +/- keys to set the required value.
If a materiel feeding error is detected, for example, in the event of damage, breakage or lack of material, printing process will
be stopped. The printer will display the "Material feed malfunction detected" message. This problem and its solution are
described in chapter VIII, point 3. The flow rate monitor value can be set within the range from 0% (OFF) to 100%.
4.1. Material loading
1.
Confirm that the filament holders and the Bowden tubes are correctly installed in the printer. The installation of these
elements is described in more detail in "Quickstart" card attached to the printer.
2.
Make sure that there is no material installed on the filament spool holder (fig. 38) you want to install the new material on.
Also, make sure that there is no filament in the bowden tubes and in the extruder (this does not apply to the first material
loading). If the material is loaded, first use the
"Unload model material / Unload support material"
option (material
unloading) - the procedure is described below.
3.
If there are no fragments of material on the holder and in the bowden tubes, the material loading procedure can be
continued. From the "
MATERIALS"
level, choose the "
LOAD MODEL MATERIAL"
option located under TOOL 0 extruder or
"
LOAD SUPPORT MATERIAL"
option located under TOOL 1 extruder. The filament loading assistant will start in order to
display the sequence of commands and guide the user through the next steps of the process.
4.
The first step of the assistant operation is to choose the right material loading temperature. To facilitate the process, the
suggested plasticization temperatures for individual thermoplastic materials are shown on the screen (tab. 4).
Tab. 4 Suggested loading temperatures for specific materials
LOW TEMPERATURE
PLA, BVOH, FLEX
PP, NYLON, PET
ABS, HIPS
190⁰C
210⁰C
230⁰C
250⁰C
The temperature can be also set manually using -/+ keys in the lower right corner of the screen. Confirm the selected loading
temperature with "
CONTINUE"
key.
5.
Cut the filament end at the angle of 45
o
and place the filament spool on the holder (fig. 38, point 1).
6.
Slide the filament end into the input opening of the filament sensor (fig. 38, point 2).
