The printing plate is heated up first.
Then the axes move to the home position and the extruder is heated.
Once the extruder has reached its operating temperature, printing
starts.
The progress of heating of the printing plate and extruder can be tracked based on the temperature displays in the upper display line.
The printing progress can be tracked in the lower status display.
During the first centimetres of printing, the distance between the printing plate and the extruders can be fine-adjusted manually with the buttons
for printing plate movement (3). If you push the buttons for printing plate movement (3), do not keep the buttons pushed, but only tap them!
For this setting, observe that the extruders must not touch the printing plate since the printing plate and the extruder noz-
zles may be damaged otherwise (loss of warranty/guarantee).
If you have performed the heat bed scan for PLA (Scan PLA) or ABS (Scan ABS), the printer should already set the optimal distance
between the nozzle and printing plate when printing. If you have only performed a quick head bed scan (Scan), you can adjust the
distance with the item "
Z Offset
" in the menu "
Configuration
" - "
Z Calibration
".
When the automatic Z-compensation is active, the display will show "
Cmp
" next to the Z-position (5).
If no filament escapes from the extruder at first, the filament infeed button (4) must be pushed until filament escapes.
It is possible that filament chips collect over time at the filament feed knurls. They should be removed under all circum
-
stances (if possible) at once, e.g. by blowing off. Check and clean the filament feed knurls regularly! Otherwise, it is pos
-
sible that the chips will adhere to the knurls and that no filament can be conveyed anymore because of this (the knurls slip
through then).
By default, the fans at the extruder run starting at the 4th layer for PLA and ABS, provided that the slicer settings have not been
changed.
Depending on the printed object, the printing result at ABS may be better without the fans, however. In that case, switch off the fans
in the slicer settings.
The tolerances of the fans may cause them to only start up at 20% or 25%.
Let the printed object cool off for a few minutes after printing. When the temperature of the printing plate is below 40 °C (see display), the printed
object comes free easier from the printing plate and you can remove it.
If the printed object does not come loose easily, you can loosen it carefully with a glass scraper, razor blade spatula, knife, etc.
Do not apply any mechanical force on the printing plate. There is a risk that the printing plate will be damaged by this (loss
of warranty/guarantee)!
To ensure stable operation, print from SD card for longer printouts. Otherwise, it is possible that printing is interrupted because the
printer is restarted via the USB interface. This can be caused by restarting the PC, re-initialising the USB controller or by a virus
scanner.
When you have completed the first printout successfully, we recommend urgently that you calibrate the filament infeed (chapter
"19. b) Fine adjustment of the filament infeed"). This compensates for tolerances of the infeed knurl.
Owners of printers with a dual extruder should also adjust the two extruders without delay (X and Y extruder offset). For this, observe
chapter "19. c) Fine adjustment of the two extruders".
