Hi all. I've been working on a plugin that will create gcode for my CNC router. This plug-in

will take your 3D model and create 2.5D toolpaths for use on your CNC. Just download the Ruby

file and put it in your plugins folder. I'm not a programmer by trade. I just started learning

at the beginning of this year. This script took me that last 5 monthes to create and it probably

is not coded the greatest, but it works!

== Information
Author:: John Groeschel
Pieces of this code came from the following:
-Hatchfaces.rb by Joel Gustafsson
-Offset.rb by Rick Wilson
Organization:: none
Name:: CNC 2.5D Profile
Version:: 0.1
SU Version:: I developed this on SketchUp version 8. I have not tested on previous versions.
Date:: 05-May-2012
Description:: Creates gcode for CNC applications using 3D models in Sketchup
Requires:: No additional scripts
History::
0.1 beta:: 22-May-2012
* Original release

Usage:

There are a couple of settings within Sketchup that need to be set. Select Window/Model Info and

this window pops up:



Uncheck the "Display units format" If you don't, the inches symbol (") will show up in your gcode

and your controller software will not recognize it. You can also set your precision to what you

want in your gcode file. Whatever the precision is set to here, is what your gcode files decimal

places will be.

A few more rules to using this script. First, the part cannot be below the X-Y plane (tabletop).

It will give an error if it is. Second, the script is set up that if looks for the closest point

to the origin in the X-Y plane to determine where to plunge down. The best place to put your part

is in the +X/+Y quadrant. If you do not, there could be a possibility that there are two closest

points to origin and Sketchup will pick one at random, which could cause the tool to plunge where

you don't want it to. Third, inside radii need to be modeled slightly larger than half of the

cutter diameter. For example, if I'm using a .25 diameter endmill, I need to model my INSIDE

fillets to .13 inches. If you really need a .125 radius, you can use a smaller endmill or model

the inside corner sharp. This is not a problem on outside radii.


Here is the model that I want to machine. The model is placed in the +X/+Y quadrant.



Your part must be in a group or this script will not work. If your model is not in a group, the

script will give you an pop-up window stating that your selection is not a group. Once it is in a

group, select it and select CNC 2.5D Profile from the plugin menu.



The option menu pops up. Fill in what you want for this cut. The values that you enter are stored

in a text file in your plugins folder. The next time you run the script, the plugin will read

these values back into the options panel.



The script will run. When it is done, a file save menu will pop up asking you where you want to

save your gcode file.



When completed, the cutter paths are displayed on the screen. The cutter paths are put on a

separate layer, so you can toggle them on and off.



Here is the output of the gcode file in NCplot

I fixed some bugs that I found while testing tonight. The latest file (v02) is available at the link in the first post.

Awesome job figuring that out!

Not sure what I am doing wrong. Make a square in sketchup 8 and when I generate the g code all seems good but the g code is not generated for the square.
Thanks
Using Sketchup v 8, free version, windows 7 64 bit.

Is the model in a group? It needs to be grouped in order for the plugin to work.
Try the attached model and see if it works and we'll go from there.

Thank you!
Is great to have another plugin to create gcode.
I also use for this purpose Phlatscript an excellent plugin.

I ask the courtesy of some moderator delete this topic in duplicate
I have not found how to do this
