I am a new user and have a big error happening that is ruining projects. This is my setup. I am using Fusion 360. I have the top of my material set to 0 for z. After using a v bit to carve text, I change the bit to a ball nose and re-probe z. I load a new program to cut out around the text. It…

Do you get the height using the probe or do you use the paper method???

I use the probe. I just ran it again and it was fine but suspect it will happen again. With my luck it will be when I am using expensive stock. .

I have had the exact same issue. Fusion, cut once, probe z, second cut plunges too deep. For me it happens when using a Spoilboard cutter. Lost a nice piece of walnut.

Happened to me as well, but always my fault. Wrong stock settings in setup once (I used two setups), wrong height settings second time (make sure you refer to correct heights especially if you make second or third bit and check your offsets…). [image]

If it’s a mistake you made in F360, you should be able to catch it by watching the simulation closely. In fact, F360 will warn you if you plunge too deep. Make sure you enable that option when simulating. [image]

You can also do an air cut. Just use a scrap block to set your Z-height well off your work and watch that initial cut. One thing I’m getting through reading all the questions about F360 on this forum is that it may have TOO many settings. -Mark

Yes F360 is complex but must agree with Alex, watch carefully simulation, it should show you any mistake you eventually make. After a few collisions I pay much more attention and also change view angle during my simulations, to be sure it really does what was intended…

After it happened, I checked the settings and they looked correct. It’s happened twice. I will follow the advice given and appreciate the help. I agree with Fusion 360 having too many settings. I am using it for free but wonder if it is a mistake. I understand it is the way it is because you c…

Hi James, I have had a similar problem. I searched on the forum for ideas. What I came across was a post describing loosing z. The gentleman posted pictures and his loosing z was the result of a faulty/loose wire to the z step motor. For my project, the z step motor wire seems ok. I used the sp…
