File to cnc table help?

Does anyone have a learning resource for having a file prepared to cut on the table? I am having issues having the tool go all the way through the stock in one pass. I need to select a face and have multiple depth passes?

I dont mind paying to learn this

What software are you using?

fusion 360 with a step file

I just saw that.
Im not familiar with that software so i dont know 100%.
When you are choosing your bit, or depth, is there another menu for passes?

there is an i am selecting everything i need so i am very confused.
is there another program you can suggest?

Are you zeroing off the material or the machine bed?
Whats the depth of cut total for the carve?
Are you selecting multiple passes?
Do you have the corrcet bit aelected?

we have zeroed both at separate times
and the depth is an an inch and a half,
i am selecting multiple depths
and yes its in the tool library

Any chance something is in mm. Instead of inches?

Hello Richard,

Have you looked for youtube tutorials?

This one looks pretty good:

Unfortunately Autodesk keeps making “improvements” to Fusion so some of the menu names may have changed, but this one is only 3 years old so it may be close enough for you to follow.

Assuming you have got the origin and stock set properly I think what you need to look for is how to set passes in the toolpaths.

thank you so much for the video ill watch it now

Its around 37 minutes it mentions passes. but its all good to watch.

The issue could be with Fusion, or something with your machine setup. Its helpful to determine which side the problem lies with.

In fusion, you can verify the toolpath with the animated playback. This is a great way to visually see if Fusion is programming the cutter to cut all the way through as you intend.

If it looks right in the Fusion verify, the problem is more likely your setup at the machine.

I can probably help out. When using Fusion, you can select the stock origin point. I like to select the bottom of the part as the origin. At the machine I would probe to the top of the MDF spoil board. The reason that I prefer this method is because it removes the material thickness as a variable. This is best suited for cutting your parts right through, for carving, I’d set everything to the top surfaces instead.


Let me know if that helps or not.

No worries, let me know how it works out!

I ordered the home steel thing that you used in your video and it will be here Saturday…
but i figured out I wasn’t doing multiple depths correctly I was doing four depths at 1mm each so it was going down 45 mm and starting.

WOW, okay, yeah I can see that being a problem. Some of those settings in fusion are a little confusing, it defaults sometimes incredibly shallow, other times, it’ll be too deep. I always set my first pass to 8mm so I can get into the down shear portion of the cutter and get a nice clean first cut, I will do a finishing pass and move in slightly to remove any stepdown lines etc. too. That probe block is pretty nice, they really need a good holder for it a standard on the machine though. I’ll probably design one and release it to be 3D printable or CNC machinable too.

still having issuies setting the wcs at the top of the stock but they gave me a step file so not sure if thats whats doing it

If you can send over the file, I can give it a go on my end as well. I don’t have a router bit with that cutting length with this Makita router setup, but I could setup a fake tool to see how it looks at least and then do a cutter-less dry run.
