Parameter Meaning
Retract
A changed retraction plane works from the last
simple
safety distance set in the cycle, because the further
retraction is carried out by the following cycle.
all
none
XRA (mm) Retraction plane X
related to XA (ink/
abs)
XRI (mm) Retraction plane X
related to XI (ink/abs)
ZRA (mm) Retraction plane Z
related to ZA (ink/
abs)
ZRI (mm) Retraction plane Z
related to rear (only if
Retract "all" is se-
lected)
Tailstock (only if available on the machine)
Tailstock is shown within the simulation and the si-
yes
multaneous recording window. While approching
and retracting the retraction logic is considered)
no
You can further expand the retraction area so that
XRR (mm)
collisions with the tailstock will be avoided when
traversing the axes.
