5.
Look at the first few layers of the print. If there are notable spaces between fill lines of the first
layer, then the print board is too far away from the hot end. If the first layer is highly transparent
or there is noise from the hot end grinding against the first layer as the second layer is printed,
then the print board is too close to the hot end. If the print board is either too high or too low,
select
Stop Print
from the Main Menu, and then select
Cooldown
. Lower the print board by hand
using the knob on top of the Z-axis lead screw. Remove the print board (see Step 8 of this Section),
clear the filament from the board, and replace the board. When the hot end has cooled down
below 50°C, perform board leveling.
6.
If the printed object is lifting off of the print board on one of the sides, the print board is too far
away from the hot end. Select
Stop Print
from the Main Menu, and then select
Cooldown
. Lower
the print board by hand using the knob on top of the Z-axis lead screw. Wait for the hot end to
cool down to room temperature, and then perform board leveling.
7.
Upon completion of the print, the hot end will move to the 0 point on the X-axis. The hot end will
automatically cool down to room temperature.
8.
To remove the part from the print board, lower the board and loosen the blue thumbscrew
underneath the print board and slide the front clamp forward. Remove the print board. Use a
sturdy, bent angled paint scraper. Do not use a putty knife since it does not have a beveled edge.
Slide the scraper underneath the part. Be careful not to scratch or gouge the BuildTak. If print is
difficult to remove and the board is level, adjust the gap by turning Z-axis end stop thumb screw
approximately 1/4 turn clockwise. This will slightly increase the distance of the hot end from the
board and ease print removal. This can be repeated until desired result achieved. Slide the print
board back into place by pushing the front of the board while holding the rear clamps. Push the
front clamp back into place and tighten the blue thumbscrew. Move the print board from side to
side to ensure that it is locked in place.
