Introduction

Version 0.3.13

P2G makes it simple to ensure that parts are in fixtures correctly, coordinate systems are adjusted to deal with stock placement and cope with movement and rotation of workpieces through multiple operations.

P2G is a compiler; it takes Python code, some definitions of machine specific variables, a little glue and makes G-code, so far, Haas ideomatic.

Thanks to magic it can do surprising things with python data structures, anything reasonably calculated statically during compilation can be used in the source, classes, dicts, and so on.

It comes with a set of macro variable definitions for a Haas mill with NCD. And a few example settings for my own VF-3SSYT.

Usage

p2g - Turn Python into G-Code.

Usage:
  p2g [options]  <srcfile> [<dstfile>]
  p2g help [ all | topics | maint | version | location | <topic> ]
  p2g build-examples <dstdir>

       p2g tram-rotary.py ~/_nc_/O{countdown}tr.nc
        Makes an output of the form ~/_nc_/O1234tr.nc

       p2g --func=thisone -
        Read from stdin, look for the 'thisone' function and write to
        to stdout.

Arguments:
  <srcfile>   Source python file.
  <dstfile>   Destination G-Code file. [default: stdout]
               {countdown} in file name creates a decrementing prefix
               for the output file which makes looking for the .nc in
               a crowded directory less painful - it's at the top.
               (It's the number of seconds until midnight, so clear
               the directory once a day.)
  <topic>      [ all | topics | maint | version | location | <topic> ]
         all      Print all readme.
         topics   List all topics.
         version  Show version
         location Show absdir of main module.
         <topic>  Print from readme starting at topic.

Options:
     --job=<jobname>      Olabel for output code.
     --function=<fname>   Function to be compiled,
                           default is last one in source file.
     --narrow             Emit comments on their own line,
                           makes text fit more easily into
                           a narrow program window.
     --short-filenames    Emit just the lsb of filenames.

Variables

Give names to macro variables at a known address:

Fixed ❰ [ size ] ❱_{opt} (addr= addr ❰ , init … ❱_{opt} )
Give names to macro variables automatically per function.

Var ❰ [ size ] ❱_{opt} (❰ , init … ❱_{opt} )
Not actually a variable, but same syntax.

Const ❰ [ size ] ❱_{opt} (❰ , init … ❱_{opt} )

Example:

from p2g import *

def variables():
    # On my machine, Renishaw skip positions are
    # in 5061, 5062, 5063.  Look in p2g.haas.py
    # for : SKIP_POS = p2g.Fixed[20](addr=5061)
    skip0 = haas.SKIP_POS

    # can be done manualy too.
    skip1 = Fixed[3](addr=5061)

    # grab 5041.. from globals oto.
    workpos = haas.WORK_POS
    tmp0 = Var(skip0.xyz * 2.0 + workpos + skip1)

    com("Define a constant ")

Expressions

Python expressions turn into G-Code as you may expect, save that native Python uses radians for trig, and G-Code uses degrees, so folding is done in degrees.

DPRNT

P2G turns Python f string into runes that DPRNT can digest.

The conversion makes print operation on vectors easy.

Extended f-string syntax

[ «digit» [ .«digit» ]﹖] f: standard Python floating point format.
«e-string» [ «number-spec» ] «e-string» [ ? «separator-string» ]﹖]
- «e-string»: Text, with some characters substituted on output.
  - ! Index of element.
  - @ Axis name of element.
- «number-spec»: A picture describing the layout of the number to be printed using # signs.
- «separator-string»: As an «e-string», but only expanded between items.

Notes

Stuff you already know

As someone who uses a machine that can reduce $1000 of flat bar into a bucket of chips, bits and coolant before you can say "I forgot to tighten the vice.", you know about some of the bad things that would happen if skynet were to notice you.

You'll make a wise and considered decision about using some random internet stranger's program to control your machine.

If p2g crashes your mill so hard it kills your cat, well, you should have seen what it did to my cat. Stumpy was a good cat.

That said, p2g makes it pleasant to write code to manipulate the translations on work pieces so that complex fixtures aren't needed.

Cool example

from p2g import *
class X:
    def __init__(self, a, b):
        self.thisone = a
        self.b = b

    def adjust(self, tof):
        self.thisone += tof.x
        self.b += tof.y

class Y:
    def __init__(self, a):
        self.val = a

    def adjust(self, tof):
        self.val += tof

    # an example of overloading.
    # I'm not recommending replacing add with
    # multiply, but it would work. Don't do this
    # if you're sending a probe to mars.
    def __add__(self, other):
        return self.val * other + 3

def cool():
    com("You can do surprising things.")

    avariable_scalar = Var(100)
    x_instance = X(avariable_scalar, 34)
    another_xandy = Var(7, 8)

    x_instance.adjust(haas.TOOL_OFFSET)

    q = Y(another_xandy) + (x_instance.thisone, x_instance.b)
    sys.print(f"{q[0]}{q[1]}")

  #100= 100.                      ( avariable_scalar = Var[100]   )
