3. CALIBRATION OF HEATBED
3.1. Indications for calibration of heatbed
Heatbed calibration is not required each time you run the printer - it should be done approximately once a few dozen to
a few hundred hours of printing. Other indications for table calibration are enumerated below.
Heatbed should be calibrated when:
• the printer is started for the first time,
• one or more corners or edges of printed model peels off or does not adhere to the working table,
• one or more corners or edges of printed model are squeezed into the surface of heatbed (the printed layer seems
transparent or too thin, printing mechanism skips layers, extruder engine makes a clicking noise or printing material
excessively accumulates in transitions between layers),
• table surface was unintentionally lifted from its bed,
• too much force was used during removal of the printout, which might have caused table displacement,
•
the first printing layer is not even - one edge is printed correctly, whereas the other edge is too flat or does not ad -
here to the surface of the heatbed.
3.2. Heatbed calibration procedure
1. Check if X and Y axes can move without any obstructions. Make sure if any cables are not frayed or damaged. Check if
the toothed belts are not frayed or damaged. Check if Z-axis stopwatch is not damaged, broken or bent, and if it matches
Z-axis limit switch (if it aims at the notch of Z axis limit switch).
2. Any filament leftovers should be removed (see „ Removing filament ”) and the head should be cooled down to tempera-
ture below 50°C.
3. Remove all dirt and leftover material from the nozzle of print head and clean the table with a spatula (not required when
starting the device for the first time).
4. From the submenu „
Prepare
” select „
Home All
” and confirm by pressing „
OK
” button. At this point, all axes will go to
their base position.
WARNING:
Carefully observe the movement of all axes. When Z axis reaches its limit switch, check the distance
between the end of hotend and the heatbed. It should be about 0.8-1 mm (no more than 1 mm), greater
distance may interrupt scanning the heatbed, which is displayed as an error „Heat bed scan aborted!” If
the distance between the hotend end and heatbed is more than 1 mm, adjust it manually to 0.8-1 mm. To
do this, release the screw (1) (fig. 30.) and adjust the distance using the knurled screw (2). Turning the
knurled screw clockwise will increase the distance between the table and the head. Counter-clockwise
turn will decrease the distance. A single full turn increases or decreases the distance by 0.5 mm. Once
you have finished knurled screw adjustment, check the position of the nozzle with the command HOME Z
and tighten the screw (1) again.
