Thanks Viesturs - now I understand what this code was doing:
it set/resets block delete
it abort execution
then restarts a line behind or a line in front
It's a really smart bit of thinking!
def zoomin(event=None):
c.set_block_delete(0)
s.poll()
c.abort()
c.wait_complete()
c.auto(linuxcnc.AUTO_RUN , (s.motion_line-1))
def zoomout(event=None):
c.set_block_delete(1)
s.poll()
c.abort()
c.wait_complete()
c.auto(linuxcnc.AUTO_RUN , (s.motion_line+1))
