1. about

It is a script for Blender. It can generate gcode ideal for LinuxCNC :) it export from mesh ( vertex / edge / edges (outlines) / objects ) to 2d, 2.5d and full 3d for (3axis mill).

2. donation

: collect on the new hardware to write code.
: accept a donation: paypal (b.ceglik @ gmail.com)
: Title: Support for mgcodegenerator
: or url: http://yoyo.ghost.pl/mgcodegenerator.html

3. requirements

program capable of reading the file type gcode. not necessarily LinuxCNC)
blender
python
linux / windows

4. tips

2d/2.5d/3d cam - gcode can be generated from the object type mesh not curve.
2d/2.5d cam - use of tool compensation is only possible with objects that have no errors in the grid. I recommend not to mix of objects made of meshs and edges. objects should be consistent. objects with protruding edges may generate errors. have not yet come to that so why sometimes the lines perfectly horizontal / vertical not generate correctly. solution is to gently rotate the object.
3d cam - to make surface tracking with higher quality put object on positive x ,y near 0,0 point. set edge detail to 5 ore more. edges will bi crisper. :)

: This version has several improvements:
: - smearing of the old head working paths. no longer have to scribble the previous generated paths :) juupiii :)
: - mega super extra button: P " Mash > Join > Fill ". specifically for work on imported dxf, automation of transactions involving merger objects (join), removing duplication vertex and fill to get objects allowing to gen toolcompensation path. Now in one click

more accurate detection of the shape tools,
options 0 `, 90` angle pass
"E" - edge detect, (http://yoyo.ghost.pl/fb/?subPage=na_tapecie&tag=edge%20detection) but in the time available to prepare and improved

ver 0.1.75

: clear g-codu generated.
: calculate the total, g0, g1 work long head
: calculate the probable time

: repaired using z-axis when generating gcode is enabled using the tool compensation

ver 0.1.61

added a function called "tool shape compensation" for 2/2.5d cam. how to use it. bearing plane. machine itself determines where the outline. downloading information about the tool diameter offset adds. if the plane will be holes. machine determines that the internal offset is added. Action objects beige faces has not changed. that the machine fared better with searching use the offset direction triangli. Check the edge of the grid. Do not use too many tools in diameter. from time to time, sometimes there are some bugs preview http://yoyo.ghost.pl/fb/?subPage=na_tapecie&tag=tool%20shape%20compensation

7. how to install it

download the latest version of the script, unzip, move it to

linux /usr/share/blender/scripts or ~/.blender/scripts
Windows XP: C:\Program Files\Blender Foundation\Blender\.blender\scripts
Windows XP (alt): C:\Documents and Settings\USERNAME\Application Data\Blender Foundation\Blender\.blender\scripts
Windows Vista: C:\Users\USERNAME\AppData?\Roaming\Blender Foundation\Blender\.blender\scripts

when you start Blender. change the type of window (lower left corner of the window) for scripts window. script should be available from the menu wizard> to gcode have fun:)

8. how to use it

Tools / speed settings:

"inch./cm." - toggle button to choice units in generating file ( not press inch. / pressed mm. units )
"CW / CCW" - toggle button to choice mill direction
"Z axis safty" - it is a minimum height of tool from work area
"Z height level" - [2d bake] at such a height above the path the tool will work with speed G01. [3d bake] height off milled single layer.
"G00 speed" - hyy
"G01 speed" - hyy :P
"Tool size" - dimensions of tool

2D / 2.5D bake:

"Bake 2d gcode (vertex only)" - click it and you will get a gcode only vertex of selected object/s.

it is cool to generate drills.

"bake gcode" if (edges/s = false) - you will gate all edges of selected object/s without edges with are share with two neighborhood faces ( :/ my english :( ).

it is perfect to generate some sign/s, letters

"bake gcode" if (edges/s = true) - you will gate all edges of selected object/s

"bake gcode (+tc)" - Tool compensation for 2d/2.5d bake. if (pressed) generator will try to make path with tool compensation. ( if "out/in" is not press you will get out of the object tool compensation, if press over obejct )

holders - it will generate a holders for milling deatail.

multipass - use for multi pass mil 2d/2.5d cam. counts of pass, height of mill pass

3D bake:

"bake gcode" it generate 3d gcode - tool will pass from top to down if "pass 90" is true it will add 90` pass
subdetect - it is value for sub detection / pubpixels. higher the slower but more accurate.
sub pass - at a sub detect the path to be generated

3D bake - diagram explaining what is what
