Can anyone tell me how to change it?

Thanks,
Kent

Cone scaling is not exposed to the user - it seems to be based on the extents of xyz.

To change it would require code changes in glcanon.py

Here is the cone twice the size - is that what you want?

I need it maybe 1/4 to 1/8 size possibly even smaller. My entire work envelope is about .060 inch.

Hey chris also did you have a chance to review my code for trying to open a camview window in axis. This thread here

in python/rs274/glcanon
look for (I added a comment to highlight it) :
                if current_tool is None or current_tool.diameter == 0:
                    if self.canon:
                        g = self.canon
                        x,y,z = 0,1,2
                        cone_scale = max(g.max_extents[x] - g.min_extents[x],
                                       g.max_extents[y] - g.min_extents[y],
                                       g.max_extents[z] - g.min_extents[z],
                                       2 ) * .5 # <- THIS HERE
                    else:
                        cone_scale = 1

Change the *.5 to something smaller

Sorry I looked at the code, couldn't see anything obvious and realized I don't have any system that has linuxcnc installed rather then RIP.
And then forgot. I'll give instructions to do it manually.

It would be nice if that could be configured by the user maybe as an ini file setting (or GUI setting) in V 2.9.
I usually leave my machine set for an overhead view and I find the cone too big.

Yes I can look into it. Probably nicer if it was adjustable in AXIS but not sure
I have the patients for that - maybe Phil can help me there...

You can hide the tool in AXIS - it's an option under view.
Not sure if you noticed.

But I use Gmoccappy :(

Surely the code is not GUI specific. A setting in {DISPLAY] section of ini file would be cool.

axis/Gmoccapy/Gscreen/Qtvcp all use the same basic code for graphics.
The underlying code changes work for all of them.

It how to change the size that will be screen defined.
The reason i say that in screen adjustment would be preferred is you can:
-immediately see the change (rather then change INI, start linuxcnc, shutdown linuxcnc, readjust INI etc)
- adjust depending if the particular program requires a change, say because lines are really unusually close.

maybe we can do both - follow INI but be adjustable in screen...

I think you would have to do both.
If the feature is not GUI specific and is part of the GUI core then adjusting it should never be tied to a GUI. That breaks the modular design of Linuxcnc.

Something like

                   if self.canon:
                        g = self.canon
                        x,y,z = 0,1,2
                        cone_scale = max(g.max_extents[x] - g.min_extents[x],
                                       g.max_extents[y] - g.min_extents[y],
                                       g.max_extents[z] - g.min_extents[z],
                                       2 ) * .5 # <- THIS HERE
                        cone_scale  = cone_scale * tool-scale
                    else:
                        cone_scale = 1


###------------ INI FILE -------------------
[DISPLAY]
# tool-scale  changes the screen "cone" that represents the tool. Defaults to 1.0 if not present
tool-scale = 0.5   

Does the other side of the scale if statement need scaling?
