Lathe Macros

Notes on the keyboard:
As well as the obvious functions and unit conversions, it can be used to enter fractions. For example if you type 1.1/2 it will automatically update to display 1.5000 and 16.17/64 will show 16.2656. This can be used in a limited way to halve the onscreen value eg for entering radius instead of diameter. However it only works for whole numbers: 100/2 will become 50 but 3.14149/2 is interpreted as 3 and 14 thousand halves so won't work.

Now that's a weird and surprising behaviour! Is there a rationale for it? If I'm not mistaken the imperial system normally uses a minus sign to denote addition: e.g. 1-1/2" means one plus a half inch? If the keyboard input supports equations I understand that the minus sign cannot be used that way. But why redefine the decimal point to mean plus? That makes no sense. Why not simply use a plus sign?

So "1.1/2" would become 0.55 and "1+1/2" would become 1.5.

Anyway, great work with the macros! Looks very useful!

Okay. I've never used (or even seen) the keyboard so I don't really know what I'm talking about.

I took a quick look at the code and the keyboard seems to be laid out with glade (loaded with a GtkBuilder from a .ui file)? Adding a '+' key to get division to act "the way it always does" (and get support for addition besides!) seems like a big improvement IMO. Obviously it's your time so please ignore my opinion as you wish. The macros should be very useful either way.

(SORTED OUT)
I DID simply copy the SIM.gmoccapy.lathe_config
and changed the DISPLAY to AXIS  and in a second copy to touchy
that did the trick

Hi i'am new to Touchy and Gladevcp
i tryed ti get the ZIP file from page 2 to run
with no success
i installed from the 2.8.2 iso and updated to 2.9 pre 7123 today
no way to get this py file to a work
please can you provide the newest touchy and axis files as a ZIP
the 2.9 contains a SIM as of gmoccapy Working 

Thank You

I have re-vamped the lathe macros for use with GTK3.It now uses features only usable in Python 3.7 , so Buster is fine, but nothing much before that.

Rather than attach a zip file, I think it makes sense to grab the up-to-date version from the LinuxCNC repository.

You will need these files:
boring.ngc
chamfer.ngc
drilling.ngc
facing.ngc
grooving.ngc
lathehandler.py
LatheMacro.svg
lathemacro.ui
radius.ngc
threading.ngc
turning.ngc

To be clear, these are the ones hiding under configs/sim/gmoccapy/lathe_configs/ , right? Not the ones under nc_files/macros/lathe/?

Are the latter unrelated or old duplicates? If the latter perhaps better remove them to avoid confusion...

Is there a plan for more macros to be
I make lots of v-shaped grooves
 

I am using older Lathe macros in Raspberry pi. Latest Lathe macros SVG image not showing.
I am using in Gmoccapy.
