2D Contour w/ Multiple Depths and Profiles - Order by Island Behavior Problem

[Anonymous]

I am having trouble getting this toolpath to behave in the way I want/expect. Perhaps I am misunderstanding what the "Order by islands" setting is supposed to do so correct me if I'm wrong, but I believe it should dictate that each depth of a given profile should be cut before retracting and moving to the next profile, but this is not what happens in practice. As well, I am applying the "Preserve order" setting which works as expected using the "Order by depth" setting but seems to go completely out the window for "Order by island". I will attach the assembly file in question as well as a screencast depicting the behavior I'm talking about.

Hi @Anonymous,

First of all only attaching a Assembly file isn’t enough. You also have to include the Parts. Make a pack and go. That’s the easiest way for Sharing your project. 

For you operations. If those setting doesn’t bring up you steps. Split the operations in more operations in order of your wish.

You're totally right, I should have realized that would be the case. I will update the attachment when I have access to my computer on monday.

However, you're solution is not a solution, it's a work around. I am quite aware of the fact that I could make 5 individual operations in order to accomplish the specified goal, but the point is that is not how the software is supposed to work and this is a workflow I will be going through many times per week with dozens of profiles per sheet at times.

Hi @Anonymous,

That the software should do that by default is also my wish. But at the moment there are some wishes about this published on the ideastation in different scenario’s. 

 nested-pattern-reorder-to-minimize-toolchanges

wcs-offset-both-direction-option

Hopefully this is something that Autodesk will pick up. 

So about the workaround I think that is the only methode at the moment.

I have the same issue and I could swear that this behaviour was only recently changed. I compared some HSM 2017 contour paths and they are exactly as you want them. Each contour is done with multiple depths before it moves to the next contour.

I also figured out that it works with HSM 2019 if you space your parts more than 2*mill diameter away from each other, i.e. tool paths do not overlap. Of course this is a waste of material, so I don't like this solution. I would seriously consider the current behaviour a bug.

Hi

I updated today from hsm express 5.3.1.63 (very old) and I now remember why I didn't updated since then.

That bug wasn't there in that version. I don't remember when this bug appeared since I always rolled back updates because of bugs killing my workflow.

I will ROLL BACK AGAIN to 5.3.1.63 to avoid this bug AGAIN.

*** ADDED INFO ***

I did rollback to 5.3.1.63 and the problem is half there. the workaround in 5.3.1.63 is to ckeck "preserve order". This workaround do not work in the current versions.

Six years later and this annoying bug isn't still resolved?!?!?!?!? I updated to inventor cam 2025 (from my very very old hsm express) and this VERY ANNOYING bug still exist!!! why should I pay that amount of money for a software that haven't evolved (very little)  since my 2016 version????? Very frustrating! Look like all the money go to fusion 360 developpement.

again IVCAM is dead they just get it to work in the latest IV, no fixes

Hello,  This is still a problem!  "Order by Islands"  still behaves in an unorderly fashion.  I does whatever it feels like, it will mill some parts to final depth and move on to the next part. Other parts it will do one depth cut and go to another part then come back to that part.  It is not at all following what it says it will do "Enabled - Depth cuts are ordered by profile"  I also have "Preserve order" checked which it is not following that order either.  There are always going to be issues and bugs but we pay a ton of money for this software and having a known issue not fixed for years and years is just ridiculous!

yes, when parts are that close together this always happens, did the same in HSMWorks (now dead).

I would just do each one separately, only way to get it to flow the way it should work, sorry. just the way it is.
