It just seems weird to have your machine zero in a spot that you rarely use as your zero, but its probably because you do not use your machine for processing sheet goods. With pop up pins, I guess its just natural to use that corner as machine zero, because sheets index with the pins into that corner every time.
When I use fixtures, I have dedicated spots for them (indexed spots) and I have each of those zeros saved as home positions in WinCNC (under the name of the fixture, I have at least 20 saved at the moment). So I just select each fixture I need and the machine automatically zeros where I need it to.
You are correct that I do not use the machine for processing sheet goods, that is rare for me.
It really does depend on what kind of work you do. In my case, think in terms of a tool shop, no repeating orders, no two things alike. I gave some thought to "fixturing" the vises, but then it dawned on me that I change jaw inserts fairly often so that goes out the window.
Sounds like you have your setups dialed in for the type of work you do. Pays to spend time to do that, no doubt about it.
Here is another thought about having machine zero somewhere in the work area. No real reason to do that because it is easy to just set something like G54 in the header of the cnc file from the post, have 5 and 5 in the offset registers and zero will then be at X5Y5 in machine coordinates.
I guess that is why so many of us like offsets, they are so flexible.
