Problems with toolpath filtering X4

[huskermcdoogle]

Guys I am having a wierd issue when filtering a toolpath. First off the toolpath should be following an arc path almost perfectly when doing a surface finish blend toolpath (blend is between two arcs with same xy center). Once I create the path and set the tolerance at .001 and the turn on arc filter, I will get backplot results that would be acceptable. When I post the code I get mostly line segments and very few arcs but there are a few arcs still intermingled in the code here and there. There seems to be no ryme or reason to it. What the hell am I doing wrong. Is there something in the MPMaster post that is breaking up the arcs that backplot is showing. If you have any quick ideas or would like the zip to go let me know and shoot me an email for the file if you want to take a look at it. I can make due without this toolpath for the time being but at the moment am I very frustrated that I cannot get the results that I am looking for here.

Maybe see if this helps you?

I changed the precision from .00001 to .0001 and the code matches the backplot now. This seems to be the opposite to what the posts in the link were saying. Anyone have anything to comment on this. Thanks though, this gives me more footing in understanding the issue at hand for future applications with this problem. To solve it yesterday I ended up just doing a swept 2d toolpath which output the shortest code, in fact even shorter than the filtering could do with a surface finish blend toolpath (same stepover and end product result).

 

 

Thanks for the help.

are you using the new X4 filter or the old school filter??

To check go to

Control Panel

Mastercam X

Select X4 in the dropdown

then

Toolpath support

and see if "Refine Toolpath" is enabled
