Area Clearance toolpath changes when I add a start depth
I am doing an Area Clearance with one Roughing toolpath and one Finishing toolpath. In the Roughing toolpath everything goes as expected, when starting from 0 depth cutting to .45 inches deep. When I set the Finishing pass, I want to start the cut where the Roughing pass left off at .45 inches down to .5 inches. However, when I calculate this toolpath, it covers a larger area than the vectors + tool diameter would suggest. I don't understand why the Finishing pass cuts outside the vector due to the Start Depth setting. I have tested this by removing the Start Depth, and essentially air cutting down to final and the area is as expected. Add the Start Depth of .45 back in and it goes outside the vector boundary.
I am missing something here, but I can figure it out.
Comments
Forgot to add some screenshots to explain a bit more:
Hi Daniel Baarts,
Your supplied screenshots indicate that the calculated Pockets and Pockets Finish toolpaths within your desk-org-magsafe.art model file both make use of the 1371 Bits&Bobs Bowl and Tray Bit. Unfortunately, we've identified a discrepancy when creating more than one Area Clearance toolpath with any other tool than an End Mill and where the second of these toolpaths includes a specified Start Depth.
Rather than specifying a Start Depth for your second Area Clearance toolpath, please try specifying a Step Down for the 1371 Bits&Bobs Bowl and Tray Bit tool so large that the toolpath only makes one cut. This should be a suitable temporary workaround.
Thanks for your time and consideration.
Well I just logged this issue as a bug with support. Why is this still an issue in the latest release?
Hi Ryan Cook,
We've replied to you in Support Request #21417.
Information regarding the fixes and enhancements included in each release are provided in the Release Notes on our company website.
Thanks for your time and consideration.
I've had this same experience when using a separate toolpath for a finishing path while using a 3/4 bowl & tray bit. However, in my situation the issue presents itself even if the start depth is not specified, i.e. still zero. The note above says the problem happens only when something other than zero is used on the second toolpath. But my case it happens even if second area clearance is also set to zero.
Please don't hesitate to reach out to see it in action if it helps troubleshooting.

Hi Barry Campos,
Please capture and share a screenshot showing all of the settings which you're using for your 2D Area Clearance toolpath.
Thanks for your time and cooperation.
The screenshot of the simulation was the first toolpath (LEFT-bowlout) that completed and then during the second toolpath (LEFT-resurface) in process of running and you can see how much wider it's cutting.
Thanks.
Hi Barry Campos,
Please check and confirm the Tool Tip Radius of the 35 - 3/4" Bowl & Tray - Whiteside#1372 bit chosen for your 2D Area Clearance toolpath name LEFT-resurface.
Thanks once again for your time and cooperation.
