tool doesn't move up when passing other model

Hello,

 

I'm using 2D pocket strategy and have some issue when the tool moves between the passes.

see the picture... The tool stays on the manufacturing level and goes over another model - and of course destroys it.

 

My question is, how this is possible. I have defined in the setup, where my models are.

Even there is keep tool down enabled for the strategy it should count with other models and move around them or am I wrong ?

 

Thanks for any ideas what could be wrong.

Select each model in the setup and also in the 2D Pocket,see images below.

Hi Rob,

 

thanks for your reply. Unfortunately it will not help.

The path for the 2D pocket is selected correctly and I have marked all the models in the main setup as well.

Still for some reason the machine runs with tool down over the second model :disappointed_face:

That should work, can you upload your file ?

Go to File>Export>Select f3d format>Save to a location on your computer>Then attach the file to your reply using the "Attachments" facility at the bottom of your post.

here is the file. Don't look at the model structure, I had to cut out a lot of things, that I'm not allowed to share :slightly_smiling_face:

But the CAM tool issue is still there...

 

Hope you can find, what's wrong...

 

Thanks

If you uncheck "keep tool down" in the link tab it should raise to the retract level to move around.

Have you tried selecting the bottom face instead of the edges ? It does jump around more even with the "Keep Tool Down" but it doesn`t violate the other model.

It appears that if you want the "Multiple Depths" then you can`t have the "Keep Tool Down", it works at a single depth with the "Keep Tool Down" so looks like you will have to turn the "Keep Tool Down" off :disappointed_face: :disappointed_face:

 

Looks like a "Bug" to me but maybe it is intended to work like this, maybe Seth @seth.madore  can get some information from the Developers ?? :slightly_smiling_face:

The worst thing is it even doesn't stop on collision in the simulation.

If I change the second body to a fixture, than it stops on collision and I can investigate,

But here... no stop at all, just damaged part / tool if I would be deeper...

 

Definitely something wrong...

It wouldn't stop on collision from the picture I saw (sorry if I missed something).  The move is a feed move (link move) and not a rapid move, therefore there is no collision per say with the part.  When you changed it to fixture, it shows collision because even with feed, you are not "allowed" to machine a fixture off.

Also, it violates the 2nd model because this is 2d machining, and not model aware.  It machines what you select with complete disregard to what's around what you selected.  It is intended behavior (as far as a know).  If you want it to automatically avoid obstacles you need to use 3d operations.

@DarthBane55 has it right; feature, not a bug. All 2d toolpaths (except Chamfer) are "dumb" toolpath and have very little knowledge of any model that it may cut through.
