Fusion 360 chamfer not correct

[davidhofer]

have a look a pic, the cutter will pick up and go down in the middle of chamfer, made new drawing and same thing…HELP please…

[davidhofer]

OK, it has something to do with origin, part is 54 inches long, moved the origin to other end of part now works good, funny.

[davidhofer]

This is happening on side 2 even more… how do I fix?

@davidhofer have you tried asking this in the Facebook page?

[davidhofer]

I just tried on my macbook, a different computer, and it worked with same settings, but yesterday I had to change the origin to get it to work. if this keeps happening I am gona try Mastercam…

It would help to see your settings in your chamfer operation. Not sure why you have the multiple retracts and the one plunge. You should have been able to pick a continuous contour path. It appears your chamfer profile is in segments.

[StephenHadwin]

I am not sure how the origin would affect the chamfer tool path. I don’t believe that is the problem even though it seemed to correct your tool path. Was the model designed in Fusion or is it an imported model?

[StephenHadwin]

The vertical line shown in the model maybe why the chamfer tool plunges, it may be trying to follow it.

[davidhofer]

Model was designed in Fusion, and no that line is not part of tool path.

[StephenHadwin]

hmmm, do you have your sketches turned off when selecting the edge of the slot contour… You shouldn’t be seeing that vertical line. It sure appears when selecting your chamfer profile, it is selecting broken entities. How many selections do you show in your chamfer process? As in my image there are only 2 chains.

[davidhofer]

I have an open chain, just the ends and one side, will share file… this is imported drawing where it happens more often, was still made in fusion, just need a right and left side.

Single part for linking to assembly part

This part is the design file for the plate. I will attach a screencast video in subsequent replies that explains

[StephenHadwin]

This is the assembly file using the single design part

Next reply will be the screencast video

[StephenHadwin]

It appears to be open now… Please conifrm

[Rumpelstiltskin]

Yes it has ben fixed thanks

[davidhofer]

HI, so I changed to contour instead of chamfer, that works beter. Thanks for the help.

Hello,

I increased the tolerance on the passes tab to 0.0005. This seems to have fixed the retract moves.

Side Note - You might want to cut that chamfer with multiple passes, .100 in one bite is asking a lot.
