Find lines #866-#869 in the RB file...
filename = UI.savepanel "Save Gcode File", "c:\\", "default.nc" #header outputfile = File.new( filename, "w" )
If you do not choose a file in the 'savepanel' the output fails badly.
Change the lines to read...
filename = UI.savepanel**(**"Save Gcode File", "c:\\", "default.nc"**)** #header **return nil unless filename;**outputfile = File.new( filename, "w" )
This exits the file writing method if you have canceled the 'savepanel' - i.e. filename==nil...

Hi TIG

Seems great work to me. I give it a try this afternoon. Before, i was using SketchUcam.
Your software was not intended to make pockets?

That would be really great, if i could also cut pockets.

At the moment it cuts only inner parts the nearest distant to the geometry.
Do you still work at this plugin? Did you know, there are other guys working on a similar project?

(www.phlatforum.com)

Maybe sharing would be great? Otherwise, could you help me and tell me how i could make a pocket with your Plugin?
Kind regards
Claus

@Claus

This not 'my' plugin.
I simply stepped in to fix some issues it had...

Perhaps someone else can advise you on setting up 'pockets' ?

I think I found another error:

( This file created by CNC_profile.rb )

Unit are millimeter, but the move in z direction is made in inches: G01 Z0.01968.... that are exactly 0.5mm. But where is the 0 level in z direction? On top of the bed or on top of the workpiece?

Also the cutter diameter is given in inches.

Did I miss something? I can't get the plugin to install. It's looking for an .rzb file. It won't recognize a .rz file. Did I miss something in the setup? -running OSX latest Sketchup version as of 01-01-16.

Start by going back one page and reading the answers to your own questions.

The Installer needs an RBZ file.
It's an old thread - the original comes in a ZIP file:
http://sketchucation.com/forums/download/file.php?id=98895
If you change the file-type suffix to ".rbz" it'll install.
You need the helper[s] mentioned earlier.

OK I got it. I found the post that said to change the name of the .zip file from .zip to .rzb and that worked like a charm. Now it's on to plugging in the gcode to my mach3 pre and post code and this should work like a charm. Thank you!!

Not to pick nits but rather to avoid confusion for someone else who might come along with a similar issue, it is not rzb as you've written several times. Instead, it is rbz for the file extension.

Hello, how to download the plugin? Or tell me is it posible to cut the pieces obtained with 3D software fusion cuisine here is the link of project SketchUp DXF:

Hi,

this plugin gives me the following error, whatever the value of safety distance is:

"Safety Height is lower than top of part. Please correct."

Therefore sometimes the program freeze and I notice in the outliner some outer and inner group being created and deleted.

The parameter "Safe distance from table" ("Safety Height" I suppose) is higher than the height of the model, so why does the message appears?

The test model and the settings used are attached, can you help me?

Other two question:

I used inches values but what happens using another unit? How exactly unit measures are managed by this plugin?
what means 2.5D? The GCode generated doesn't rappresent a truly 3D model?

Thank you.

Since your part is less than 8 in. tall and the Safety Height is set to 9 in., it's no wonder you're getting that message. What happens if you set the safety height to half an inch?

thanks for your reply

first of all the safety heigth is NOT lower than the top of the part,
furthermore even if I lower the value to 7.5 (smaller than the height of model) the message still appears, so definitely the message appears in both conditions, lower or higher then the heigth of the model.

Did you test my model?
Can I have a working example?

Dave R · 7 Jun 2016, 22:05

You can make your own working model. Get rid of those hidden grids and try it again. It works fine for me without the grids. You'll have to unlock the one parallel to the red axis before you can delete it.

Thank for your help Dave!

But still remain some serious glitches.

Those grids where not selected so why the plugin process them?
Therefore I exported the GCode for a simple cube, the file is attached and opencam gives me the errors reported in the screenshot.

As you can see the decimal number are written with comma insted of point and this is not valid.
I replaced the characters and the model is displayed correctly.

Then I tried to work the model posted here but the program, after have processed it correctly, doesn't show the save dialog and crashes.

At this point I wonder what the correct workflow is to generate GCode with sketchup? I open a thread in "SketchUp for 3D Printing" section but for some reason was moved in "SketchUp Pro & Make Discussions":
http://sketchucation.com/forums/viewtopic.php?f=15%26amp;t=65111%26amp;p=597157#p597157

Can you give me some hints?

I have just found this plugin and would love to have a go at using it, but I cant get it to work on 2013. Will it work on this version or newer versions?
Thanks

Did you try following TIG's directions here?

I ran it in SU2016 and showed an example of the output.
