You can uncheck "add polylines", they are not necessary for machining, (I use them internally to create the surface) I kept them just in case, for other uses such as exporting to DXF to use them with another software ... or other hacks :)

thanks ;)

Another trick ; to place the model, first rotate it so it is aligned with the Y axis, then use "Edit/transform/align" with the following settings so the model is centered on the revolution axis (Y)

X = center
Y = none
Z = center

be sure that all values are set to 0 in the bottom boxes.

Hello

Your model should be fixed using 'join option'

+1, you must end up with an unique 3D surface.

I can't unzip Bubba's example too see, but the job is done in to stages:

Unrolling the 3D model to obtain a "flat" 3D surface that can be used with standard 3D surface operations, then wrap the resulting Gcode with Wrapper plugin if you're using CamBam V0.98, or the RotaryX or Y post processor if you're using V1.0 (it is more easy to use the post pro to wrap)

1) Unroll 3D model to get a "flat" surface of the unrolled model. Your 3D model must first be aligned to Y axis to perform the unroll operation, then you can use a standard 3D surface machining operation to generate the toolpath on the unrolled surface.

2) Use the Wrapper plugin or the Rotary post processor to wrap the Gcode

Hi, How familiar you are with Un-wrapper plugin?

https://cambamcnc.com/forum/index.php?topic=6427.0/index.php

Your model should be fixed using 'join option. Got you started, just use as an example because I'm working with inches here.
David, the plugin creator will help you if you have questions, as of now I'm busy, sorry.

Edit: Fixed the zip file.

Small business in Florida, he builds the CNCs and did all the programming, custom running software.  Fantastic support, i.e. I asked him and he said he'd program that feature in for me
https://productionautomation.net/

It look like linux based control software.
