This folder contains a number of simulated lathe configs.

the "lathemacro" config offers a number of simple macros to perform
the most common lathe operations.

The GUI that controls the macros can be viewed by clicking the "Cycles"
tab top left of the graphical preview window.

There are two load-time options to control the tab behaviour:
1) norun will hide the action button, use this if you want to use only
a physical button (connected to gladevcp.cycle-start) to start the macros
(Strongly recommended, especially with Touchy)
2) notouch will allow keyboard editing of the spinboxes. Otherwise the
custom numeric keyboard will be shown.

An example loadrt line, as used here in the Gmoccapy demo is:

[DISPLAY]
EMBED_TAB_COMMAND = halcmd loadusr -Wn gladevcp gladevcp -c gladevcp -U notouch=1 -U norun=0 -u lathehandler.py -x {XID} lathemacro.ui

The window will resize slowly if you grab the corner and move the mouse
inside the window. It's not as bad as it was, but still needs work. 
You may need to click the unmaximise button in the toolbar to get a
window border to be able to use the resize handles. 

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.

Notes on adding your own cycles:
Create a new G-code subroutine in the same format as the existing ones.
In Glade add a new tab to the 'tabs1' notebook and give it a name matching
the new cycle.
Edit the action button (inside an eventbox) to call the new G-code sub.
Rename the action button to match the tab name and append '.action' eg
MyCycle.action

Create new artwork. I used Fusion360, the models are here:
https://a360.co/3uFPZNv
and the drawings are here:
https://a360.co/3uFPZNv
Esport the drawing page as PDF and import into the lathemacro.svg file in 
Inkscape. You will need to resize. Add your own arrows and annotations.

Save the new layer in a layer named "layerN" (lower case) where N is the
tab number, starting at zero. You will need to invoke the XML editor for
this (Shift-Cmd-X on Mac)

The entry boxes are positioned relative to a 1500 x 1000 image; the
original size of the SVG. So you can hover your mouse over the image in
Inkscape to determine the coordinates. 
In the in the case of on-drawing controls the coordinates are entered as
an XML comment in the Tooltip for the control in x,y format (The surface speed,
tool and coolant do not need this, they are in a fixed table)

An example:

<!--300,711->Peck distance

Make sure the comment has "use markup" selected for the tooltip. 
Also ensure that the control has the "show_keyb" function allocated for
the Widget->button_press event. If you copy-paste a tab and copy-paste
extra controls this should be automatic. 
_All_ your new spinboxes will need their own new Adjustment, or they will
change value when you alter the original spinbox that they are a copy of.
