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.

My results

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?

Hi,
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?

Hi,

I would like to know what is the correct workflow in Sketchup to obtain valid GCode.
I know there is SketchUcam but I dont know if it is still supported.

There are several plugin like Slicer or SliceModeler but they generate only sections out of model.
Those plugin are still manteined and what are the differences between them?

What is the correct way to generate GCode in Sketchup?

Thank you.

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.
