I messed up a part today doing something stupid.  I'm hopeing you can help.
When i hit the "goto zero" inthe run program screen the x&y move started long  before the Z.  Braged across part broke bit etc etc.  Shouldn't the z move complete to a "safe" postion before moving the X&Y.  this may change based on which axis you define as primary move axzis.   Your thoughts

have a look at this thread.
