Engrave - Multiple Depths - Bug with files and explenation

Hello! These are my first steps with CAM Engraving and unfortunately while doing my first things for family I encountered a known to forums bug, but as I searched forums it is known for many months and by some posts - it is fixed now, but by some others - it still occurs.

 

I will attach screenshots and a proper file with bug explanation.

 

The thing is - Fusion is doing very inappropriate toolpaths when using Engrave with Multiple Depths.

As long as "maximum stepdown" is lower value than the depth of engraving that would happen without multiple depths it works fine (screenshot "1mm"), but when you increase that stepdown further to a number that is deeper than the maximum depth of a cut that would occur without multiple depth the toolpath starts to do some strange things at this place, don't cut anything or just scrub and destroy material (screenshot "2mm").

 

For me it is some kind of awesome easy to fix bug, the program just need to check the maximum depth of cut without multiple depths and if the multiple depth value is bigger than normal max depth then just take by default the normal max depth for that toolpath. It isn't doing that right now.

 

I also attach the file that gives me problems, but it's easy to replicate on any engraving toolpaths sticking to the rule of depth as I mentioned before.

 

This option in it's current state is not usable by any chance.

 

I will also try and tag some specialists that I found in other posts - @seth.madore  @Anonymous

this bug is still occurring in the latest version.  Do you have an estimated fix date ?  And what is the work around in the meantime ?

Unfortunately, no, I do not have a date or any other information at this time :disappointed_face:

This is a very annoying bug/problem.  Can you please make a recommendation for a workaround in the meantime of fixing this bug ? I engrave many graphic shapes and images, having many different width closed paths.  I make the graphics in another program and import it into a sketch as an svg, (because F360 has problems editing many nodes and splines), then I can simply select the sketch contours in the toolpath step.

The workaround that I use is one of 2 and neither is good.

 

workaround 1)   define an Engrave toolpath using no Multiple Depths on the Passes tab, and allow the maximum default depth to be applied to Bottom Height on the Heights tab.  This creates one pass and properly cuts all size (width and depth) of closed contours.  Then when running the job on my CNC, I +offset my Z0 to a distance that is a multiple of the step down I would otherwise have used in the toolpath in F360.  For each pass, I have to decrease the +offset of Z0 until it is actually Z0 at my stock/model top.  This can be error prone.

 

workaround 2) define multiple Engrave toolpaths where each has an decreasing -Z Bottom Height where the decrement is the Z stepdown distance that I want, do this until the max depth is reached for the V bit that I'm using.  This is problematic in that for each iteration of change in the model, I have many toolpaths to update, and can be very error prone also.

 

Please advise if there is an alternate milling operation that I can use or if there is an alternate workaround for the Engrave operation.  Or, hey, here's a thought, fix the **** bug.

The ticket called out above (CAM-23125) was fixed in August of 2022. I assume that means you are still having issues? Please share your part here and detail what it is you're running into; I'll get a new ticket logged to investigate your issue.
