I don't see offset polyline (W) in your file.. What was the offset value you were using?

I was using the default value from the plugin. I might not have saved it.

I switched from inches to mm so I could use the calculator values. Cam Bam did not convert my drawing to mm. Started over using mm and things look a lot better.

This statement is telling me that you have lots of reading in front of you.. Are you familiar with those documents?
http://www.cambam.info/doc/

Now, to explain this.. CamBam use  unit count, being an inch or metric it does not matter as long as is used as configured in the option menu. Because my program default measurement setting is Inch all plugins, scripts operate as such. In my case, in the inlay calculator all of the values entered were in inch and it works , no problem..

As Bubba said, if you use inches then just enter a value such as 0.125 and if using mm enter 3.2.
In other words you have to use values appropriate to your chosen measurement system.

Also make sure you use the new v1.5 because it will remember your values.

I had the drawing units set to inches. I ran the inlay plugin. The substrate offset value was something like -0.638 I don't remember exactly and my laptop is at home. The number was too big. Instead of converting all the numbers from mm to inches. I selected mm in the drawing units drop down. This converted my 4 inch letter to 4 mm. Again the default -0.639 offset was too big. Figured out how big 4 inches is in mm. Started with a new file with mm set for drawing units. Put in the right numbers and it worked.

Still playing around with it. Is the inlay v-engrave go inside the region?

hi ,

I installed the plugin but is there some explanation on how to use it ? I have a work to to. I am making an oak table and on the table top in need to engrave a text " SUDAH MAKAN ".

My first idea was a v-engrave but as it has to stand out it is maybe better to do it with a inlay . Text needs to be 5 cm height and 15 cm long.

If someone could push me in the right direction i would appreciate ;-)

Hi David

yes but this is very complicated. You almost need have a programmer background to find out how to do it. Is there any possibility to create a video showing every step to take to get the  inlay done on a tekst ? This will be much easier to understand then trying to unravel this technical text ;-)

Hi Michel,

I apologise completely for the complexity of my description of this process.  I AM a programmer as my day job, and it comes through in my approach to things.

I don't have a video myself, but on the first page of this thread Billt posted a good link to a Vetric video that covers the process, albeit for a different platform.  Thats all I have!

This really is rather tricky and took me some days to work out, which is why I wrote it up in the first place.  I just wish I could express things more clearly.  Sigh!

Hi ,

i attached the text i need to have  on inlay. If it is not asked too much can you make the inlay and it can then figure out how it was done for future ones ?

regards
Michel

Hi Michel,

I guess you called my bluff!

I attach my attempt at your inlay.  I must start with all sorts of weasel-words about this being for illustration purposes only - at your own risk - this could destroy your machine - not my fault, etc.  I would not normally provide a .cb file completely untried.  I have made no attempt to set up feeds-and-speeds.

I should also say that I did this using 9.8, not 1.0, since I am not sure if the v-Engrave is working yet.  I was getting warnings in 1.0 about v-Engrave, but much has happened in the last few days and I am probably not current.

But that said, I thought I should try to help, and perhaps this might also assist someone else.  Here we go!


Your file included 'text' objects, so the first thing was to convert these to polylines. Since you have nested lines (the letter 'a'), I converted the polylines to regions. V-engrave needs regions for nested shapes.

I see that your file used mms (good choice), so I made arbitrary assumptions that I would use a 90-degree v-cutter, that the Air Gap would be 2mm, the sanding 1mm, the Inlay would be 4mm thick and the glue 1mm.  I plugged all this into the Inlay calculator, which gave me an Inlay Offset of 6, Substrate Offset of -10, Substrate Target Depth of -6 and Inlay Target Depth of -7.

Fortunately for you, but unfortunately for my example, your letters are all very thin.  There are no broad areas that need to be roughed out.  The substrate can be v-engraved as-is, without the need for an inside offset, and there is no need for a substrate roughing pass.

I followed the description on the first page of this thread, making four copies of the original curves, each on a separate layer.  The substrate engrave layer is good as it stands, and the second roughing layer is not needed.

The third layer, the inlay engrave, is where the fun starts.  Follow the description exactly as to the use of the offset, convert-to-region and union operations, and then the select all on layer and convert-to-region.

In the fourth layer, I added a rectangle around everything.  I did not leave myself enough space, so it goes over the axes.  Sorry.

See the description for how the mops are set up.  Note carefully the stock surface for the substrate engrave.  The substrate pocket is not needed.  The Inlay engrave stock surface is -4.  The final inlay pocket, using a milling cutter, has a roughing clearance of 3, which is half the Inlay Offset, and a target depth of -7, as given by the calculator.

I am being rather aggressive with the v-engrave cutter, which is going rather deep for one pass, especially in the gap between the two words.  Either a thinner Inlay depth would have been better (less than the 4mm I picked) or perhaps the inlay engrave should be done in two passes, lying about the stock surface for the first pass.  I don't know what your machine can manage - check your extents.

Anyway, I hope that this is useful to you and wish you all luck.  Please be careful, as I say, I have not tried this!

Bob

Reading back, I see you are making an oak table.  You should certainly test all this on scrap wood before you waste good oak!
