V-Engrave Plugin

[GeoffreyGRoy]

Dear Eddy

Many thanks for the updates, the default Optimisation Mode seems to work just fine.

On some further testing I note that there are some odd behaviours with the Stock Surface settings.  If the stock surface it set to 0.0 or a -ve value then the results are OK.  If however, the stock surface is set to a +ve value then not all the cutting paths are produced.  It is of interest to note that if the stock surface is high enough so than the max depth of the V-cut is still at +ve Z, then only the final cut path is produced (correctly I think).  This may not be an important issue as it might be normal to cut the Vee paths from the stock surface and downwards.  Like the +ve value for Max Depth, users need to be aware of the possible issues.

Version 15.03 attached

In response to this thread; https://cambamcnc.com/forum/index.php?topic=9519.msg73857#msg73857

Added information messages to log window;

"Deepest Z found"
"Max theoretical Z for tool"
"Auto max Z"

 Deepest Z found - this the deepest Z required to fully V carve the selected objects.
Max theoretical Z for tool - calculated as the maximum depth the tool can cut before the flutes meet the shank.
Auto max Z - if "Auto" is selected for "Max Depth", this is the calculated maximum depth of cut for the tool. Should be same as "Max theoretical Z for tool"

Please note the values reported are all POSITIVE  Z even though they refer to a depth that is normally regarded as NEGATIVE Z.
This is because the original code was written this way and it's too much of a task to change it.

Hah, Gunter!

Eddy's already DONE the math for you! <grin>

Oh, well.  I guess you don't need to learn trig for this one...

Hello Eddy

Seems that some negative values for Stock Surface cause infinite calculation loop.(*)

Example on the attached file

-0.1 > OK
-0.15 > infinite loop
-0.2 > infinite loop
-0.25 > OK
-0.30 > OK
-0.40 > infinite loop
-0.45 > infinite loop
-0.50 > OK
-0.60 > OK
....

The fact that it works or not seems also dependent of the drawing ; on the example file, it works with -0.6 but on another drawing (not attached), this do not works for -0.59 to -0.62 (and works for -0.6 and -0.63)

(*) negative values are used because it's the values given by the Inlay calculator plugin.

Hi all!  It's been a while, but I have another engraving job to do and need to update the plug in.

I'd like to add all the changes people have made to the source code in GitHub (assume someone didn't branch the project).

I gather that the current version is build 12?  GitHub only has build 5.

Seems like some, but not all of builds 6-12 have zips attached to this thread, but I'm having some trouble loading some of the pages in this topic.

Hello

The sources of V15.02 are here
https://cambamcnc.com/forum/index.php?topic=3513.msg72223#msg72223

the very last version is 15.03, but no sources available currently.

PS: since V14, you can use depth increments

Source project for 15.03 attached.
I for one am very pleased you are going to make right what some of us have most likely made wrong.
It was not the easiest code to fully understand.

[pstemari]

Yes, the code uses a lot of vector algebra, in particular dot and cross products.

I did a lot of gesticulating with my hands as I was writing the code and thinking of the vectors.  Unfortunately I didn't video that

Hello

Have someone tested the V-engrave plugin under Win11 .. ? on a french forum a guy said it is not working.

I have not.  I won't own Windows 11 unless forced to do so at gunpoint. 

But I wouldn't be surprised.  Hundreds of applications have been crippled by Win11, including Windows itself.

Yep and seems that it can not works on all PC, you need UEFI bios and another thing that I don't remember the name ....

I'm still using W7 LOL (and XP)

But maybe it is a .net framework (4.8 ) that must be enabled in W11 ... as we need to enable the 3.5 in W7 and 10

I will give a feedback if this is the case.

It works for me. V-Engrave v15.03 on an up-to-date install of Windows 11. I used it a couple of days ago to engrave a serial number on a brass plate.

[EddyCurrent]

The plugin works fine for me on Windows 11, maybe it's a .NET issue or the dll 'unblock'
