3D Adaptive Clearing returns error 'empty toolpath'

I'm trying to do a test/calibration carve on my new machine using adaptive clearing. However, whatever boundaries I select or settings I use, I just get the error 'empty toolpath'.

 

The exception is if I turn off rest machining, it then mills the outside of the block. Not what I want, and I also don't understand why this would happen!

I'm pretty sure I'm missing something obvious, but if anyone can point me in the right direction, would be a great help. Cheers

Adaptive is going to be about the worst toolpath you can imagine if you're trying to get it to cut an Adaptive in those slots and pockets. You have about 1mm of clearance on each side and your machine is not gonna like it one bit.

If this is a test piece, I encourage you to increase the size of the features or decrease the size of the tool.

 

Problems with current process:

1) Min cutting radius is set to .6mm. You only have .5mm on each side of tool between the slots

2) Stock to leave is .5mm, thus rendering your toolpath nonexistent

I get the same as Seth @seth.madore  for this, your 6mm tool is way too big and as Seth rightly points out Adaptive toolpaths are not right for the job, both the 3D and 2D Adaptive toolpaths will work with a 3mm tool, if you want to use your 6mm then the best toolpath by far is a simple 2D Pocket 🙂

Here is a 3D ADaptive using 3mm cutter.

Yoy could even use a 2D Contour or a Trace toolpath 🙂 🙂

That's a good point - there isn't enough space for the adaptive part of the toolpath to take place...

Thanks to both of you for pointing that out!


There's something I don't understand though - why does the 0.5mm stock to leave make any difference? The pocket is much deeper than that...

It's not the depth, it's the width
