Question / Error / Problem
How does the print data get
en
from the PC to the printer?
Why is a WiFi connection not
recommended?
What frequency band is used
by the Simplex WiFi module?
Can acetone be used to clean
the print bed?
What grease should be used
to lubricate the printer?
Is a spare nozzle included in
the scope of delivery of the
printer?
The graphic in slicing mode is
shown in black.
What is the minimum required
height (in mm) of the model
base above the palate in or-
der to facilitate an even sur-
face during printing?
G-Code file cannot be loaded
from the USB flash drive.
When placing models with a
thick model base, is it possi-
ble to reduce the size of the
model by placing the model
base slightly below the print
bed?
Is the SIMPLEX sliceware
only available after the cus-
tomer has registered using
the Renfert app?
What distance is recommend-
ed between print elements?
What is the recommended
minimum distance?
Cause
• In the case of a poor WiFi connec-
tion, the connection between the PC
and the SIMPLEX may be interrupt-
ed with the result that it cannot be
ensured that SIMPLEX print can be
used securely and reliably.
• Driver problem
• Umlauts / special characters in the
file name.

Troubleshooting / Solution
• We generally recommend printing via USB flash
drive: the G-Codes are saved from the PC to the
USB flash drive. The USB flash drive must then be
inserted into the USB port of the printer.
• If the printer is located adjacent to the PC, it is pos-
sible to print using a USB cable: the USB flash drive
is not required. During printing, the connected com-
puter must not be shut down or switched to stand-
by / energy-saving mode.
• Printing via WiFi: Only recommended for WiFi net-
works with good coverage and few outages. The
USB flash drive must be inserted in the USB port.
The USB flash drive is used as an external storage
medium.
• If data transfer via WiFi is not stable, we recom-
mend printing using a USB flash drive.
• The WiFi module of the printer only operates at 2.4
Ghz.
• No, acetone would damage the Kapton. Corre-
sponding cleaning agents are listed in the IFU.
• Grease is not included in the scope of delivery of the
printer.
• Generally, PTFE lubrication grease should always
be used.
• A spare nozzle is included in the scope of delivery of
the printer.
• Update of the graphic driver.
• The model base must be approx. 3 - 4 mm above
the palate.
• When slicing the working model, approx. 2 mm of
the SIMPLEX sliceware is removed. Remaining
below this distance can result in holes.
• When saving, do not use special characters or um-
laut characters in the file name!
• Yes, this is possible. Everything that is positioned
below the virtual plate is shown in red in the SIM-
PLEX sliceware. These red areas are not taken into
consideration during printing.
• Yes, the customer only receives the link to download
and install after they have registered in the app.
• The distance between print objects should be kept
to an absolute minimum in order to minimize the
travel times of the extruder and as a result, printing
time.
