"No passes to link" in 2D contour

[Anonymous]

I am new to fusion 360 and I am trying to mill a 2D contour in 11mm stock with a 1mm flat end mill in eleven 1mm steps.

When I try this I get the error "No passes to link".

Any idea what this can be?

Usually when this happens it's because there are some settings that conflict, or you've told it to machine something where the chosen tool it too big to fit.

We would really need to see your file (or at least screen shots of all the settings) to figure it out.

Can you make it download-able?

Ok, I see the problem.  You had the bottom height set to "selected contour" and the selected contour was on the top of the model.  Which means that the top height and bottom height were the same, therefore there is no cut to be made.  So you just need to change the bottom height to "Selection" and then select a bottom edge or face (as shown below).  Or you could change your selected geometry profile to a bottom edge of the part instead of the top.

I added a small offset so that the cutter will go a little below the part.  You tend to get cleaner edges that way.  Of course that means it willl cut into anything below the part.

Ah there is the problem. I can not believe that I wasted hours on this.

I already made the model 0.5 mm thicker to achieve clean edges in the
end. The original model is only 11mm.

When I put the geometry on bottom then this will be my zero on the
machine, but i need to start on stock top since the sheet of stock is
bigger.

Just out of curiosity: any particular reason to use 1 mm end mill?

You could easily get away with a 4 mm mill, which is much more rigid, so it can take deeper cuts etc. etc. And for outside, an 8 mm end mill would save you a lot of time.

The reason is I dont want to change the tool and the smallest holes are
1.7mm. I could use a 1.5mm one...

I changed now to a 1.7mm drill and for the second operation a 2mm router bit.

The drilling went fine until he started the second operation without wanting a tool change. So the drill broke then.

Do I need to activate some option for the tool change? I referenced two different tools in the operations.

I tried only the second operation after changing to a 2mm router bit. I went 2mm deep per pass and the bit broke too.

The feed was around 4mm per minute, but I think the machine moved faster than that!

I was milling in particle board. I use a weihong NK105 controller.
