I’m trying to surface my wasteboard using Fusion 360. The first picture shows the toolpath in Fusion 360, and the second shows the error in Onefinity. Any ideas? [Screen Shot 2022-04-10 at 5.19.35 PM] [Screen Shot 2022-04-10 at 5.19.53 PM]

I believe with the toolpath you have that extends past the material, which also includes the overall width of the surfacing bit in its calculation, you are asking Fusion to move past the maximum cutting area available. I do not have my 1F set up yet, but I am sure you will soon get the solution you…

It appears you have increased the value for “pass extension” which when combined with the “smooth” transition type has generated a toolpath that exceeds the working space (soft limit). Since you’re pushing the outer boundaries of the machine I would suggest changing the transition to “straight” and…

Thanks, Derek. I didn’t increase the pass extension myself, but after reading your response, I checked it, and it was set to something like 0.794 in. I set it to zero, and now I’m getting the same error, but on the Z-axis :smiley:

Do you have the actual error message for the Z axis? Surfacing bits are usually very short and it is likely you are just at the end of the travel.

Ok, the Z-axis issue was due to me not zeroing the z-axis. Rookie move. I fixed that. Now I’m getting this error after the router goes to the far right of the X-axis and makes the initial cut with the surfacing bit, and stops: [Screen Shot 2022-04-11 at 2.43.43 PM]

same issue as before, your toolpath is going to go outside the cutting area in x by -1.016mm (left).

I guess that’s where I’m getting confused. I have a 32.5 inch wasteboard that I want to surface, and in Fusion 360, I have a 32.5 inch sketch that I’m using for the toolpath. When I run the NC file with the 32.5" setting, I get the error I posted originally.

Dan Don’t forget to factor in the diameter of the bit (or radius) when machining to the limits of the working area. Reduce the tool path to compensate.

Derek - I’ve updated my toolpath with your suggestions, and here’s the current settings, but still getting the same error: [Screen Shot 2022-04-11 at 3.06.25 PM] [Screen Shot 2022-04-11 at 3.06.10 PM]

the cutting area is 32.125 (with slight variences), not 32.5
