Adaptive Roughing Generates a segfault in the python scrip #251

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Attempt to do an Adaptive Roughing operation

What is the expected output? What do you see instead?
A generated NC path 

What version of the product are you using? On what operating system?
On Xubuntu 9.10, fully updated with svn revisions:
HeeksCAD:  1280
HeeksCNC:  1116

Please provide any additional information below.
Running this from the command line ( python post.py ) generates a Segmentation 
Fault.  
When run within HeeksCAD, the operation just instantly returns and nothing 
changed.  No NC code in output window.

I have attached the model (just a block with a code subtracted from it) I am 
trying to generate NC code from and all the generated files as a result of 
attempting to generate NC code.  

Perhaps it is setting I have wrong?

It's pretty finicky stuff. I spent a lot of time recently playing with libactp 
and found that it's pretty sensitive to a lot of variables. Look at the python 
script that HeeksCNC generates (post.py in this case) and notice  
'actp.settoolcornerrad(0)' and 'actp.settoolflatrad(1.5)' I 'think' that 
cornerrad is actually the radius across the flutes of the tool, not the shape 
of a ball end mill or bull end mill. Reverse those two values first thing. I've 
been meaning to get that reversed after I am sure about my hunch. 
Another thing I figured out was that you can comment out a bunch of the setting 
variables and still get a tool path that works. It makes you hang on to your 
sanity a bit longer, if you can get something happening right away and refine 
it later. 
So try commenting out as many of the variables as you can and then go back, 
uncomment them one at a time and see what it does. 
If you comment out all the bounding box stuff, the tool will start in the lower 
left hand corner of the part. Another thing that I found was that you can start 
the tool -inside- the *stl file and get a tool path. Weird, but I think the 
program just bounces the tool against stl triangles.  
I am going to write something up on my blog soon (if my kids let me) with some 
images.

no feature requests here, just bug reports for HeeksCNC 1.0
