Lathe Macros

[EDIT 13/11/22 The various versions are now available for download here: github.com/andypugh/LatheMacros/releases ]

[EDIT 12/7/22 See here for an updated GTK3 version forum.linuxcnc.org/41-guis/26550-lathe-macros?start=240#247195 ]

I have re-vamped the interface for my lathe.



The config is attached as a ZIP file. This is a sim-config just for playing about with.
Note that it uses features only included in Master (specifically the ability to read HAL pins in G-code)

The macros now receive the values as subroutine parameters. so the FEATURES option is not needed.

Also new is the ability to type "3in" and have the value automatically become 76.2 to use imperial values on a metric lathe, or type 75mm and have the value automatically become 2.95 for the reverse
You can also type "tpi" for conversion to mm pitch, and the fractions /2 /4 /16 /32 /64 too.

So, if you want you can type "2 5/64in" and end up with the value in the box of "52.784"

[EDIT 13/11/2016] I have now made a re-sizable version for touch-screen use: forum.linuxcnc.org/41-guis/26550-lathe-macros?start=150#82743

Very nice!

I am still ironing the bugs out, but I made parts with the system this weekend.

The main problem at the moment is that the GladeVCP tabs steal keyboard events if the mouse pointer is over the tab.
ie, if the mouse pointer is on a part of the screen that is not the GladeVCP tab, then keyboard jogging in Axis works normally.
However, if you move the mouse pointer onto the tab (no need to click anything) the the cursor keys change values in the spinboxes, rather than jogging the machine.

Actually, the real main problem is that the "turning" macro is badly broken in the version I posted. There is a confusion about diameter/radius implicit in the G-code routine. I will fix this soon.
In the meantime, don't use this config on a real machine.

Question, how would one go about adding this to their own config?

There are a few glitches I am ironing out (like, I forgot to make the facing sub pay any attention to angle, and I really can't get threads to work)
Also, the tool-per-sub thing is really annoying me, I am going to do away with that, and have a setup tab to choose a tool and possibly set its offset. (This is part of a plan to stop using the Axis touch-off button as I am forever getting mixed up between tool and coordinate system, and messing up the whole thing)

But, other than that, it can live in a tab alongside any other options, and really doesn't get in the way at all. It just requires a few INI file entries and some G-code files in the config directory (deliberately out of their normal position)

Feel free to experiment with the published version, and let me know what you think so far. Just possibly leave out the tool or the workpiece
