Subject: pauseAtZ plugin: Make 15mm in Z park height configurable
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=3093914fb43e6f8a579dcf97e188b98592cb7786;p=cura.git

pauseAtZ plugin: Make 15mm in Z park height configurable

Just after retracting, and before parking the head, we move the Z
upwards.  Previously the minimum parking Z height was always 15mm.
The comment says:

  Change z before doing the move because the nozzle
  can hit the glass lock on the UM2

On my TAZ-5, this is not necessary.  And moving the Z axis a long
distance before parking is undesirable because Z axis moves are slow,
leading to a certain amount of ooze, etc.

So make the minimum Z parking height configurable.  We retain the
previous fixed value of 15mm as the default.
