pycam DropCutter


I made a sphere, saved it as an stl file.
I ran this DropCutter test in pycam, see picture ( click on it for full size )
I opened the NC file in HeeksCNC output window; which backplots it.
At the line of code shown ( for example )
X6.8000
X-7.0000 Y-4.0000
X-6.8000
It cuts back through the sphere!
What am I doing wrong?

in pycam there are path generators (DropCutter and PushCutter) that gererate a sequence of cutter locations.
you need to set a a PathProcessor (eg. ZigZag) to make a toolpath these
(see SimpleGui) these should be adding the gc.safetyheight()

Lode,
Thanks. I have made an exporter that read your pathlist and calls my "feed" and "rapid" function ( see http://code.google.com/p/heekscnc/source/browse/trunk/PyCamToHeeks.py ). See my next blog entry for a picture. Thanks for pycam. I will try some the other machining types later.
