Radius or Step movements

[killall-9]

I just wanted to confirm on this:

 

There are two passes in this code sharing the same toolpath.

 

The only difference as you can see if you has stepped movements to make up the radius and the other doesnt.

 

The first toolpath is chosen with the "Chain" option

The second with the "Partial" option.

 

Does this make the difference in code it generates to move in a radius movement ?

I would assume 1 toolpath is filtered and the other one isn't.

[killall-9]

I'm not sure what that means, if is in the parameters under Arc Filter/Tolerance niether are checked off

[killall-9]

I did end up fixing this by checking off the arc filter @ 1:1. I have never had to do this before. Is there a reason it is needed and other times not ?

That Arc filter will clean up a contour along a spline. Without that turned on splines around a curve will look like a bunch of straight lines. I usually set it to 2:1 and set the total tolerance to .0002"

HHmmmm, ya i'm working from a DXF, so maybe i'm getting lost in translation somehow. Like i said i havent had to do thsi so far, and i've used many imported DXF's

[uncle_dolan]

You could try using the "simplify" option from the edit menu. this will convert splines to arcs. If that doesn't fix it try the "break many pieces" option and select to break into arcs with a relatively small tolerance...This is all if you want to edit the geometry rather than your arc filter.

[Rotary Ninja]

I get splines in DXF's just about as often as I do on models. So to say you are working from a DXF and are randomly having this problem doesn't surprise me at all. Analyze the geometry that is creating the straight lines. It will show a spline instead of an arc more than likely. If that is the case you are going to want to use the arc filter tolerance setting to smooth it out.
