Gary,

There is currently a discount deal with Rhino to upgrade from any previous version to the new Rhino v6

I think the toolpaths are created by that strange front edge of the surface combined with the Boundary Margin required to cut the back of the surface. In reality the surface is not ideal.

updated cb file attached.

1. top of surface = Z0
As you say, that is the most common configuration and the one I would use myself. Choice is mostly down to the nature of the stock. If you need a particular amount left at the bottom then zero to bottom of stock, this is ideal if you don't want to cut into the machine table, e.g. if you use a vacuum table.

2. a new Boundary Line (46) that helps with the surface front edge.

3. changing Boundary Margin to 0.27" will allow full depth cutting.

Using 3D CAD software to create that surface seems the best plan to me.

Gary,

Found this on page 90 of 0.9.8 manual

$toolchange Inserts a tool change instruction, based on the Tool Change definition in the post processor. If the tool number has not changed, no tool change code is inserted.

Try the attached, it's not perfect but it's closer. (I'm a bit pushed for time)

1. Clearance plane must be set higher than top of object, yours was lower
2. There was a mix up between inches and mm. for Boundary Margin, you don't want 1.5" margin
3. I changed the tool to a generic number, you should change that back to match your own library.

Gary,
I think we have been here before, this version does not do something the older one did and you wanted what the old one did.  Cheesy

Learn,
You need to draw the profile line for the diameter you want then offset it outwards by the radius of the ball mill you are using. Then use ProfiletoHelix on that line.  Then use an engrave on the resulting helix.

Not with this version, it already does ball nose compensation.

User settings are stored in a .config file, the location on my PC is here,
C:\ProgramData\CamBam plus 1.0\CamBam1.0.config

It may be that something prevented CamBam from opening it at startup ?

Templates are also stored in the same directory, C:\ProgramData\CamBam plus 1.0\templates
so it could be there is a problem accessing that main folder. (C:\ProgramData\CamBam plus 1.0)

Note: If you use version 0.9.8 the path will be, C:\ProgramData\CamBam plus 0.9.8

Some plugins can be selected in plugin tree, some in diferent drop out menus?.. Huh  

This is a real issue, it would be logical to keep plugins in the 'Plugins' menu but for those like V-engrave it makes sense to integrate them into the CamBam interface.
I've thought about putting my own plugins in a sub menu off 'Plugins' but there's no logic in that really.

It looks like the procedure on how to use Profile2Helix was not followed according to it's manual.

As Bubba said, the answer is to set optimisation to 'none', however now we have the file that idea is not going to be enough on it's own.
For the plan to work, the entity ID's must be entered into the MOp 'Primitve IDs' list in the actual order required. e.g. left to right, top to bottom.
Presently they are not in the required order.
All the points could be put into one Pointlist, it is not usual to have only one point in a pointlist.

Please ensure you have installed this plugin first; http://www.atelier-des-fougeres.fr/Cambam/Aide/Plugins/ThreadMilling.html

Diameter is set in, "Hole Diameter", pitch is set in "Depth Increment".

'Joining' the lines as you suggest is the correct method that everyone uses.
15  Support / CamBam help (General usage) / Re: additional z offset being added somewhere on: December 27, 2017, 20:36:30 pm
I can't see anywhere in the gcode where Z moves to 0.25, my assumption would be that you did not set Z zero correctly to the top of your workpiece.
