Been engrossed in Fusion 360 lately trying to learn–so far good, though 3-D modeling and the software is a steep curve to get around. I’m now about ready to try to run a two-sided job and I’ve watched a bunch of videos, and some things have me stumped. I plan on using a “pin” or dowel method for indexing stock (and have a pretty good idea for that), understand how to do the setups for each side in Fusion CAM, but what is throwing me is the WSC setup and zeroing in CM once that is done and before the files are run. Bear with me for this rather long set of questions.
First, in most of the videos, the recommendation is to flip the z axis in the Fusion WCS when doing the setup for the second side so that Z is up as oriented to the stock’s backside. I get that part. But in a couple videos (here’s an example at about 12:30 in) the recommendation is to “pick up” the stock on the bottom in the CAM setup rather than the top (as was done on the top-side milling operation). Now, if one does that, this generates a series of questions for me on job setup and setting zero:
Should the Z zero be reset to the bottom (to the wasteboard) before running the back-side files? Or does one just flip the stock and leave the setup alone since Z was originally set to the stock top (which is now facing down) and the software knows top is now facing down?
Presuming Z is not reset (left alone from operation “A” side) and a face milling operation has been done (as was in this video), would that not necessitate a re-zeroing of Z since the stock would be thinner? Or is the software “smart enough” to know that a certain amount was taken off the face (which is now presumably sitting on the wasteboard?
My confusion is compounded by this video where at about 12 mins in he flips his stock, but does not re-zero Z (presumably because the stock thickness has not changed) and Z zero is in the same place for each side. In the CAM setup he picks up the WCS off the top of each side to be milled merely flipping the Z axis but leaving orientation to the top of the material.
Thanks in advance for any suggestions.
