Yes, even better ! Wink I forgot it ...

Re

If you want a shape as on the attached picture, you can use a 3D model + 3D machining mop, or this plugin.

Hello

You can't obtain this curvature with this tool size.

on the picture, the green lines shows the finished shape with r = 0.469 and deep = -.112, obtained be using tool diameter = 0, so you can see exactly what would be the finished shape, without tool compensation. (a sort of simulation  Smiley)

as you can see, a 0.375 tool can't cut such curvature. This curve can be cut with an endmill or a very small ballnose.

also, it's not needed to set cutwidth to 1 in the mop, to do roughing, in the side profile section, set Adjust cut width to True and you'll get a roughing.

Ok... then, not a 'bug'.  But it's still something to be VERY aware of, and cautious of!

Hello

Yes, this is not new, the drill mop use the center of any selected object as drill center ; for electronics some use that to drill to the center of a square/rectangle used as soldering point.

also tested with cutviewer, and all seems to be OK  Huh

Even this new file seems to be OK for me on both 0.98 and 1.0 ... no swap from a shape to another.

is the video working this way ?

Hello

I have a quick look on your file ; the first thing that I show is that the 3D model is not at the right Z position ; the top of the neck is at 8.5 inches in the Z plane, where your machining operation (MOP) use a stock surface = 0 and a target depth = -1.

3D model position and value in the MOP must match.

Have a look on your drawing with a perspective view Wink

You can use the alignment tool to solve that

Hello

 Grin

The strange things is that if I simulate your file (on CV or with the Toolpath View Filter), the result is the same on 0.98 and 1.0 .... and the "holes" are machined each after other, without to jump from one to other ...

Maybe I don't understand well what is your problem ?

the video show the toolpath sequence on Cb 1.0

++
David

Note: I change nothing in your file, I just add a stock to be able to simulate with CV, and I set my own post pro (for Mach3 too)

Just opened the project with .98 and it looks OK.

So, shall we consider there is a problem (bug) in ver. 1.0?

BTW, there is also one other glitch - .98 interprets 1.0 spiral drill as canned cycle and vice versa.

Hello

Maybe it should be reported in the bug section with a link to this topic ?

Using a point list does not show rapids but I have to try it on the machine.

open the resulting .nc file in CB, and you'll show all the rapids Wink (an useful trick to check rapids between mop, or to check if there is no "bridges" when engraving text)

for multiple part, you can use a nesting based on a point list and use this point list for all parts. (this avoid some problem with copy placement)

Hello Bubba

You can use this brand new script to save a selected surface to STL (in the case of your frame, first join the 4 surfaces to obtain an unique object)

Unpack the zip and store the .vbs file in your script folder (or in script2 folder, if you are using the Script Launcher plugin for CB V1.0)

select an unique surface object then run the script.

Hello

Also in Camotic, use the toolbar icon "Reduce the cut surface triangle count for more compact export" (at the right side of the "run simulation" button) before to export as STL, if not, you will get a very big STL file that can be unusable as is.
