Axis/joint naming (lathe subspindle)

The problem with the preview/backplot window is the limited customization options which makes it quite useless in more complex setups. Would be nice to have the possibility to rotate and mirror through external commands.

I think that's what I stumbled across yesterday - external control of the backplot view.

I looked in the QtPyVCP tutorial and found the backplot setup page.  The tutorial describes creating buttons and linking them to the backplot view orientation and zoom controls.

 

I'm speculating that if we can do something with on-screen buttons, maybe we can do the same thing with external controls (i.e. an M-code or hal pin or similar).

And the LCNC user manual page for QtVCP has similar description of setting the view for the backplot widget used in QtVCP GUI's.

 

While it's likely going to be a pain to figure this out, it looks promising.  I'm envisioning the backplot automatically flipping between front tools and back tools (flip along Z), as well as main and subspindle views (flip along X) depending on what's being used at that point.

Thanks for poking around in the code!

I'm not really ready to implement this stuff yet - or at least fiddle around in the code.  Not that I know anything about backstage code stuff, but my lathe is about 40% complete and the computer is hibernating in the operator panel (minus all wiring & electricity).

Looking at what you posted, I wonder if additional pre-defined views can be added?  Maybe a "Z3" or "X2" that can be called using the analog hal pin you used?

I also fear anything useful is going to be GUI-specific rather than a universal solution.  While looking around during my last post I did check the code in the qtpyvcp repo and found similar, but not identical, files/code in one of the widget folders.  Basically the same thing, with similar-named pre-defiend views.

Maybe a pull request, or a new topic in one of the GUI forums to get some developer help (or ideas) on how to achieve a more GUI-agnostic view flipping feature?  I'd really like to see something integrated with the tool table (or similar) so that calling a tool number with a back-tool flag set will automatically flip the view.

You're awesome.  Bookmarked for future use.

Hoping I can get the rest of the hard parts machined this weekend and start assembling the lathe.

Resurrecting this one as I'm at the point of fiddling with the GUI.

I've edited axis.py, glnav.py, and axis.tcl as indicated.  However, the additional view is not showing up in axis menu or view buttons.

Tried changing INI to [DISPLAY] LATHE=0, and [DISPLAY] GEOMETRY=XYZCV but still no joy.  Wonder if the preview takes the data from [TRAJ] and not [DISPLAY].

I suspect I'll have to sort this out for the particular GUI once I decide on one.
