Shell placement
instructions:
The shell is placed on the
bottom plate 3 by default.
The placement area is
3-4-1-2; you can move the
shell position.
2.3.7 Shell Placement Mode Setting
The shell is broken up and printed in one
stroke. For example, the character "i" will be
automatically divided into 2 shell parts. When
this mode is selected, the surface of the model
is smoother and has no seams, which is more
beautiful. This mode is recommended for
printing simple shell shape (circle shell).
Print the word as a whole; it prints the entire
shell first before printing the next. When this
option is selected, a blue highlight mark will
appear on the bottom surface; the printing
order is character by character. This print
mode allows removing and producing the
printed shells first.
The shell is printed in one piece and won't be
split into several parts. This mode has higher
productivity when printing, but seams are
created on the surface of the shell.
The shell will be printed in layers. It first prints
the first layer of the first shell, then the first
layer of the second shell, and the first layer of
the third shell. The shell will be printed by
layers in turn. This mode requires all the shells
to be printed before the shells can be
removed.
