Finally got deepnest to work outputting an optimized part layout for a 3x3ft sheet. However, after importing the file into Fusion, it takes half a minute to select any more parts after about 15 or so (with fusion seemingly wanting to crash). This results in me having to make several output cut paths, and attempt to line the parts up between ea set of cuts, which never really do.
Are there any settings that could help reduce this lag so I can get all the cuts into one output file?
The quickest repeat cutting I do is to make the first cut. Return to work zero and move in the x or y direction to the end of your current cut then “Zero all axes.” You are ready to cut you next repeat cut.
The accuracy of the machine should be well within that tolerance. The plasma stream would be the only issue. With good consumables and correct settings you should be ok. You may have some warping due to a thin skeleton.
In FireControl you simply press “Go to Work Zero” and the torch will reliably return to the last coordinates where you had “Zeroed all Work Axes”:
After returning to that 'previous Work Zero" you can then move the torch in the x or y direction. You will be able to see in the visualizer when you had cleared the previous cut position. Now you “Zero All Work Axes” again and you are ready to cut your pattern again, in a new section of metal. Kind of like a “poor man’s nesting.”
I have tested it and it works as well. I just never know if I have enough metal left for more that one more cut. I seem to always be trying to use up scraps of metal.
But, yes, the nesting function in FireControl is easy to establish.
I guess that is kind of idiot proof, minus me obviously. Didn’t realize that was a thing. Would be better if it stated “Move Torch XY to Last Work Zero”…
Spose this will help me “return to zero” if I have to make a few different gcodes using the same ref stock point for different “sets” of the nested items, if I have to divide it up to keep F360 from crashing.
Anytime that Tin does these videos, not only will you learn more about what you are currently trying to solve but will learn 2 or 3 other things that will explain or help you with future issues. Never fails for me.
I’ll start a live stream soon on how to deal with these sketches that have 10’s of thousands of sketch objects that makes fusion 360 preform poorly.
Thank you TW! I don’t know why there are so many nodes on the geometry. It’s all based on actual math based curves. Maybe it was the export / import from my freecad (onshape) into deepnest that created them. I spose there’s no selecting start points with this many features w/o making my computer second guess life?
