Duringtherstcentimetresofprinting,thedistancebetweentheprintingplatesupportandextrudercanbecarefullyne-adjustedmanuallywith
the 4 knurled screws at the bottom of the pressure plate. Turn all 4 knurls alternatingly and observe the printed line.
Forthissetting,observethattheextrudermustnottouchtheprintingplatesupportsinceitmaybedamagedotherwise
(lossofwarranty/guarantee).
Itispossiblethatlamentchipscollectovertimeatthelamentfeedknurl.Theyshouldberemovedunderallcircumstanc-

The fan at the extruder runs by default from 4th layer for PLA and ABS, provided that the slicer settings have not been changed.
If the fan does not run properly, check if it may be attached unevenly.
When you use the preassembled device or the optional heating plate kit,
let the printed object cool off for a few minutes after printing. When
thetemperatureoftheheatingplateisbelow40°C(seedisplay),theprintedobjectcomesfreefromtheheating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totheprintingplateortheprintingplatesupport,sincethismaydamagetheprinting
plate,ortheglassplate(onlymakerconstructionkit)maybreak!Lossofguarantee/warranty!
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.
