Title: Please Test My Stick Fonts and Let Me Know If They Work For You
Post by: GeorgeRace on February 04, 2011, 00:00:02 am
I have been working of converting a group of fonts to Open TTF Stick fonts.
Attached is a .CB file that has samples of all the 8 Stick Fonts I have been working on.
By turning on and off the MOP,s you can generate the G-Code and see the results.
The very first MOP contains samples of ALL the Stick Fonts and will generate a G-Code file that is over 7000 line long.  That is why I added the individual MOP's so you can test the results of each Stick Font a little quicker and easier.

Before you can run the .CB file in CamBam you need to load the Stick Fonts into your font directory.
You need to download the attached Stick Fonts and install them first.  Your fonts directory is located at:
C:\WINDOWS\Fonts  Just cut and paste the 8 font files into that directory and they will install automatically.  They are in a folder in the .rar format.

You will note that they all start with 1CamBam so they will appear at the very top of your Fonts list after the install.

I find they do work faster than the more conventional TTF fonts as they don't need to be cut both inside and outside.

After you select a font in the CamBam Text routine and start typing, you may find them to be quite faint in the background.  Also you may see some solid objects as, for example, an "O" is totally filled in.  Just one of the quirky things that are happening with the conversion that I am using.

I am not sure how helpful this font set will be, but I sure do like it for the things that I am doing on this end.  Using them I have cut my engraving time by more than half.

Making the G-Code usually throws some kind of an error as well, but it does not seem to bother the final engraving results.

Please give them a try and let me know if you think they can be usable for your engraving needs.

Hello george,

Very, very nice fonts.
it makes you take a long time to do this  :o

I think they will be very useful for me for engrave tiny text on wood .... thank you  :D

just a little reproach ;), they are no accent (éàè ....) .... useful in french

This are the fonts I downloaded from www.sawmillcreek.org (psfonts.zip) that were not working with my cad program. They only worked in with inkscape.

However your repaired packet now works on all my programs.

Thank you, I can now remove other line fonts and don't have to waste my time using inkscape only to create dxf with text.

Dejan


Maybe you can add this font to this collection

Hello Dejan:
I am glad that you can use the fonts.  
I will try to convert the one you attached and add it to the previous post if I can get it working.

Thanks,
George

ADDED EDIT BELOW
-----------------------------------------------
It converted just great and is a nice looking font.
I have added it to the .rar file and it is attached below.

Apologies if I'm not understanding something but I get errors "Error setting new poly start" using your fonts with the attached file but not with the existing non-stick fonts. Is this the sort of "G-code error" you refer to?

best regards

Peter
Title: Re: Please Test My Stick Fonts and Let Me Know If They Work For You
Post by: GeorgeRace on February 22, 2011, 12:58:58 pm
Hi Peter
Yes, the "Error setting new poly start" is the error I get with all the stick fonts after building the G-Code.

I wonder if there is something about the fonts not being a closed poly-line that causes the error.  It does not seem to cause any problem with the engraving/milling, but is an agitation to see every time you build the code.
Maybe Andy can weigh in and let us know what may be causing the problem, and what to do to correct it, if anything.

I did a simulated run in Mach3 and it does everything just fine.  You do have a difference in the diameter of the cutting tool between engraving and milling and that is also giving an error that the tools don't match.  You are probably already aware of that.

I did make one small change in your CamBam file.  Under the "Drawing" tab I selected "Machining" and then changed theFastPlungeHeight to .1    That will save a lot of time waiting for the Z axis to come back to cutting height after each move to the next cutting position.  In your case, it will cut the machining time to about a quarter of what it was.

I like your compass rose, very nice looking work.  If you don't mind I will probably "steal" your design for some future use.

All ttf fonts must have closed loop :)


Can you add this two fonts into the package?

Dejan
Title: Re: Please Test My Stick Fonts and Let Me Know If They Work For You
Post by: GeorgeRace on February 23, 2011, 01:14:35 am
Dejan, I looked closely at the fonts you want added.  Both have open spaces between loops if you enlarge them enough, so I don't consider them to be "stick fonts" like the ones that I am doing.  No matter how large you make my fonts, there are no double line path's visible in any of the characters.

With my fonts, even though your cutting tool will make two passes over each letter, they are EXACTLY on the same path, no mater how large you make the letters.  To me anything else is not a "stick" font.

I would like to keep the fonts package as truly single line if at all possible.

George

Post by: toplakd on February 23, 2011, 08:08:08 am

Post by: davek on February 23, 2011, 16:10:52 pm
OK, so I just used a trick I've used before on your fonts. I used "remove overlaps" on them. A quick look at the G code file and it seems to not be going over them twice.

It would be really sweet if someone wrote a script to automate that.

Highlight text
convert to polylines
Make a new layer and make it active
remove overlaps
delete text on original layer (or just delete original layer maybe)

Then you could just type away and run the script and have a single pass stick font.

These fonts ARE pretty neat.

I'm using 9.7 still.
Title: Re: Please Test My Stick Fonts and Let Me Know If They Work For You
Post by: GeorgeRace on February 23, 2011, 18:06:50 pm
Hi davek, I like your approach to making them single pass.  If you don't mind, I will include that information on the web page that I am building for the fonts.

I find that using the double cut, going both ways over each of the letters, gives me a bit cleaner looking finished letter.  I do a lot of very small sized, 1/4 and less, and always look at the finished cut magnified to see how clean it is.  I also use a very small "bull nose" end mill to do the engraving.  Really makes it come out very clean and smooth on 6061 T6 aluminum that I am using.

It's kind of a double edged sword, needing to have the fonts be able to install themselves under windows as TrueType, and still having them appear to be a truly single line font.  All the fonts are built using a 100% overlap in the font design, which tricks my TrueType font design program into thinking they are really looped TrueType fonts when they really don't have an inside and outside loop.

Thanks for the tip on making them truly single pass in CamBam.  I like the idea of a script to do the extra work for you, that would really be neat.  Maybe someone out there reading this will build one to use in CamBam. 

I am using 9.8i and find it to be very stable, at least so far.

Hi George,
I like the fonts (Very Nice). So here is my project I've been working on with your fonts. Its not quite done. I haven't done any MOP's yet still working out the details.

I still have to make three more wheels for my clock. I hope the picture works.
So Thanks again

P.S. If my picture doesn't work I Hope the clock does :D

Hey George, I used your fonts on several new projects (and really like the way they look) but noticed some printable character symbols are omitted like the "@" character.

Could you brief us on which of the ASCII character set was omitted?

Thanks
Title: Re: Please Test My Stick Fonts and Let Me Know If They Work For You
Post by: GeorgeRace on February 24, 2011, 15:28:35 pm
The included ASCII Characters are all of the alphabet, upper and lower case plus ! $ & ( ) + ; : " ' ( ) . ,
The missing are:  @ # ^ * _

CamBam Font 9 does include the missing ones above.

They will work and look good with most of the converted fonts.

Hope this helps,
George

Hello,

First off, great fonts… I am having a great time using them in different projects.
I have come across a strange issue. I made up a small “cheat sheet” that I engraved for spindle speeds and such and I used font 7. Some of the letters are not coming out correct. In the word “Size” the letter i winds up coming out capitalized when I do not want it to, but comes out lower case and OK right next to it. Also the letter “u” in the word “up” and “cut” wind up having their tops filled in looking like a small letter “a”. I have rebuilt the file from scratch a couple of times and this issue keeps popping up. I have noticed that when I generate the machine paths they look different on the words size and mill. Maybe it means something….
Any help would be appreciated.

I’ve included a copy of one of the files and I am using Mach3.

In reading your response it just dawned on me that there may be a reason to selecting the post processor to match your machine software. I don't remember doing that when I switched over to 9.8. It just might make a difference.. I'll have to give it a try tonight after work.
Thanks for your inputs..

Post by: dh42 on March 07, 2011, 20:21:38 pm
Hello Mark,

A wrong postpro can explain problem on the CNC but not with the display in Cambam (text or toolpath).

I think about Tools/options/TextCurveTolerance parameter, but I will be strange that it can change uppercase / lowercase.

for info I have 0.05 in TextCurveTolerance and I try with both 'mm' and 'in' for the default unit.
I try to write some text with font n°7 and no problem found

even with 0.5 in TextCurveTolerance and tiny size (5mm) I have no display or toolpath bug ....

Hi Mark:
I just tried running your .cb file and it really look very nice.
Do not see any of the problems that you indicated.

I think you may have something wrong in the Post Processor as others have already indicated.

Please let me know if you find there is indeed a problem with the font.
Thanks,
George

Post by: CanAm1 on March 08, 2011, 02:12:23 am
George,
Thank you for the kind words..
Well, I reloaded the processors, tried both mach3 and mach3cv, tried Davids "text curve tolerance of .05" and still get the same thing. It appears my explanation did not get across right. My little cheat sheet looks fine in cambam, but when I generate the tool paths the letters in issue do not look the same from the standpoint of lines, colors, arrows, it does look like a bunch of geberish.. The real test is when I load it into mach3. This is when I can tell things are not right. Anyway, I went and changed to font 3 and my symtoms changed. The 2 "U" letters in question look fine now in mach3, but the goofed up "I" has changed words. Instead of being a capital in the word size it has now changed to the word mill. Really strange... Again, any help is really appreciated and I will see if I can come up with some screen shots or something...

Mark

Post by: lloydsp on March 08, 2011, 02:21:56 am
Ahh... TOOLPATHS!

You did not say, "cuts on the mill."

You know that when you generate toolpaths, ALL the paths the tool will take, including lifts up to the safe clearance height, recursions necessary to begin a new cut, and all sorts of apparently "unnecessary" tool motions will be shown -- not JUST the actual cuts, themselves.

You may just be looking at EVERY motion the tool will make, and confusing many of those for actual cuts.

Have you run this through CutViewer, or some other simulator, to see what the work will look like when finished?

(HINT... change the machining colors to something drastically bright for actuall cuts, and dim, dull colors for everything else, then look at the toolpaths, and see what you see.)

Unfortunately I have 4 or 5 cut already trying to get things to work.
I am going to try and attach some screen shots of what I am getting.

First shot is of the file in cambam... Look OK.
Second is a shot of the tool paths..
Third and forth show mach3 shots of how it will look. I panned the image to show how the letters are goofed up.
I'll post an actual cutting in a second...

All,

And last but not least is one of my actual engravings.
You can see how the letter "I" in the word size is capital, but in cambam it's small case which I want.
Also you can see how the 2 small case "U"s in up and cut have there tops filled in..

Thanks

Mark

What is your clearance plane set to?  Does the bit sufficiently clear the stock for rapids?  The examples of the mis-cuts seem like the cutting tool might not be clearing the stock during rapids???

Post by: blowlamp on March 08, 2011, 08:41:12 am
Mark.
Try setting the MaxCrossoverDistance to zero in the Engrave 1 MOP and see if it changes anything. I think the distance between the body of the lowercase 'i' and it's 'dot', is less than than the 0.7 MaxCrossoverDistance of the ToolDiameter, that you are using for the cut and I think the same thing applies to the lowercase 'u' too.

What really seems strange is that the "i" in Mill is OK, but the "i" in Size is not.   And they are close together in the same row.  Could it have something to do with the IJ setting in Mach3 or CamBam?

George

George, note that the toolpaths are different on the two 'i's, and that both legs of the U are cut down in the same direction, forcing the tool to do a "jump".

I'm guessing that the basic tool diameter is large, and the crossover distance is too large.  Those bad cuts are obviously NOT full-depth engraving (especially, look at the offset in the top of the bad 'i', and the 'u').  It looks to me almost as if the tool began moving up to safe, but started the rapid before getting up to the clearance height.

That, then, would be a setup issue -- either the crossover distance is too large, or Mach3 is somehow misbehaving on very small details where the tool must move only a few thousanths between moving up to clearance and down to the target depth again.

LLoyd

 ;D Success  ;D

First off, my clearance plane was set at 1/8 inch (pretty high) so I was not dragging the bit.
It was the MaxCrossoverDistance setting that did the trick.. Set it at zero, re-ran the tool path and g code generation and you could tell right away in mach3 that things were better. Of course I had to run an engrave to test things out and it turned out right on the money. Cool...
Since I am still going to consider myself a fledgling beginner.. What and how (in simple terms) does this MaxCrossoverDistance setting work? Also, should or can I keep this setting at zero for everything I do? (That way I don't have to worry about it)
Thanks so much guys... It's great when problems are solved...

Hello

Little info about MaxCrossOver here

http://www.cambam.co.uk/forum/index.php?topic=1551.msg8631#msg8631 (http://www.cambam.co.uk/forum/index.php?topic=1551.msg8631#msg8631)

You can set it to 0 for engraving, but not for other MOP, because you will get round trip in Z at each change of toolpath (in a pocket by example)

George
Title: Re: Please Test My Stick Fonts and Let Me Know If They Work For You
Post by: blowlamp on March 08, 2011, 18:35:39 pm
The MaxCrossoverDistance is provided to reduce the number of Z axis retracts when moving from one toolpath to another and the value entered represents the decimal fraction of the selected ToolDiameter for that MOP.

So with the MaxCrossoverDistance set to 0.7, this means that a 10mm diameter tool can move up to 7mm in the X,Y plane, without retracting between cuts, provided that the straight line distance from the end of one toolpath to the beginning of another is less than 7mm, but a 5mm diameter tool would only move up to 3.5mm, with the same setting.

If you leave MaxCrossoverDistance set to zero, then you will see more tool retracts.

The upshot is that if you change your ToolDiameter or text size, then the retract behaviour changes as well.


Martin.

Hi, thought I`d join the great stick font debate. Have tried the stick fonts and find that the down strokes as in n,m ,etc don`t come down as far as the round letters o,u etc. Have converted to polylines and removed overlaps but to no avail. Does anyone know of stick fonts that work? It seems such a basic requirement that seems to be causing so many problems. I`m using size 8 which is quite small.

Hi George,
 I was referring to the stick font style letters, I ended up getting the hang of it.  I had to play with the tool path a little and would have been really easy if it would have just followed the stick I tried to import.  I had to use three mops set to inside, first was inner, 1 with a slightly reduced tool path and to finish it up the letter "N" and "K" had a little left at the intersections.  Thanks for the response though ! :)

Here's what I ended up with

George,
Thanks so much for the stick fonts.

Just engraved a couple very small dog tags for my dogs.
Each tag has the dogs name, my phone #, My Vets name, My Vets phone # and the Vet Id number for each dog
All the information above fit onto on a tiny .75" x .71" tag.

I Reduced stick font#9 down to .1" tall text
I used a V shaped engraving bit
Material was .0625" thick 6061 aluminum sheet.
I engraved the text at .005" deep
I wish I had some metal dye on hand. I used a sharpie to color the text and then rubbed the surface with some steel wool.

The tiny tags came out nice and the fonts look great!
They looked better before I used some sand paper on them and scratched them.  :-\

The two tags below were test runs
I am doing two more that are a bit taller with a .125" hole so I can mount the tag onto their collars.
Also, I sanded the surface, which scratched it and you can see the scratches.
I will just use steel wool on the new tags after I fill the letters with a sharpie pen

I have shots of the finished tags later

To clean up a surface on aluminum I use Green Scotch Pads, they really do a very nice job of finishing off a piece of material.

yeah, I forgot about the ole scotch brite trick, they work great.

I saw In one of the post above that @ was missing from one of the font sets

Quote
The included ASCII Characters are all of the alphabet, upper and lower case plus ! $ & ( ) + ; : " ' ( ) . ,
The missing are:  @ # ^ * _
CamBam Font 9 does include the missing ones above.

I guess that means that font sets 1 through 8 are all missing the characters shown above?
font set 9 is the only set that has the extra 5 characters
Is that correct?

Quote
Yes, the "Error setting new poly start" is the error I get with all the stick fonts after building the G-Code

I get this error also but the G-code cuts fine

One thing I did notice:
I use AutoDesk Quick CAD to draw my dog tags and used stick font 9 in those CAD drawings
I saved the CAD as DXF so I could import into CamBam as I always do.
In the drawing tree there was an extra text entry below every line of real text
When I click on this extra text line, nothing is highlighted on the screen
So I deleted all 24 of these extra text entries.

Not sure exactly what these extra items are?
See my screen shot
There is a real line of text and then the next line is an unknown item
See the screen shot below


I cut four more dog tags this morning
This time I made them tall enough to have a .125" hole for mounting on a ring
I actually glued two back to back so they are double thick and have text on both sides.
I think I had the bit depth set better in my first test, but these will be just fine.
Here's a shot of the double thick, double sided tags - see the image below
The one on the left is a better cut depth
The 6061 is kind of soft. I prefer harder Alu, but that's what I had on hand

"I wish I had some metal dye on hand. I used a sharpie to color the text and then rubbed the surface with some steel wool."

I use industrial crayons, just finish the plate any way you want to and rub the crayons in to the letter groves. Wipe of with cloth and you have nice looking tag. This method was often used in the tool room to mark fixture stamped clamping info, jig hole location, etc... Hope this helps.

Interesting about the extra line being added to the MOP from your CAD system.  I have not seen that before and have no idea what is the cause.  I will try to recreate what you did, from AutoCAD to DXF to CamBam, and see it I get the same results.

Yes those 5 symbols are missing from fonts 1 thru 8.  But, you can use the insert the missing ones, using font 9 and unless you are doing really big lettering they will look just great.

A comment on your dog tags.  The final cut really looks rough and I wonder if it is the kind of tool you are using.  I have not had good luck with "V" type tools for engraving, except in plastic materials, and there they work just great.

I use a very small ball end tool, I think I currently am using a .01 diameter ball end, to do my airplane ID tag engraving.  Take a look at my web site for an example.

http://www.mrrace.com/mykitairplane/dataplate.htm

Click on any of the three in a row at the bottom of the page for a close up look.  They are all done in 6061 T6 aluminum.  The first Cessna is a good example of the smoothness of the engraving.

I think the ball end would be better, but the smallest I have here are 1/32" ball ends.
I tried a 1/32" but the letters on the tags are too tiny for a 1/32" ball.

The 1/32" ball looks great with .25" high letters.
I did a test with .25" high text and it was very clean.

My cuts were too deep on the final tags with the V cutter
The first cuts on the test tags were less deep and came out better.

Oh well, they are just dogs tags.

If I did a ton of tiny engraving, I would spring for a tiny ball bit.

Anywho, thanks again for the great fonts.

I use a very small ball end tool, I think I currently am using a .01 diameter ball end, to do my airplane ID tag engraving.

I am now engraving my dials and then filling the engraving with epoxy paint which is then sanded off to make a perfectly flat surface.  I am very satisfied with the engraving bits I got from Dixi.  They are 60°Vs with a spherical point.  Just what the doctor ordered IMHO.  I used a 0.2mm for the indexes and 0.1 for the text.  As I wanted a specific font I just milled the letters out as a pocket and didn't use engraving.  It worked perfectly.
The first image is a trial with some red paint for the contrast.

Note that although I didn't mill this case in titanium myself, I did mill an identical piece in brass which along with the the movement and part milling was all done with CB.

I have just finished up converting another font to (almost) a single line Stick Font.  I say almost because the individual letters are true type with only about a thousands separation of the inside and outside outlines.

This font set ONLY contains UPPER CASE, lower case, and numbers 12345467890

I converted it for use on plastic engraving materials for name tags, etc...  It has a very nice looking face and can probably be used for other applications as well.

I have named it 1CamBam_Stick_0 so when you install it in your font file, it will be the first font up for selection in the font box.  If you have already downloaded and installed my other group of files, you already have CamBam fonts 1 thru 9.

PLEASE NOTE:   I attached the file as a .doc file.  After you download the file to your desktop, change the .doc extension to .ttf    You can then drop it in your font folder, under the C:\Windows directory and you are ready to go.

George, I've added Cyrillic letters and some of the punctuation marks to the font. Also Windows Cyrillic1251 code page to the font table. Did some curve cleaning too, hope for the better.
Tried the Cyrillic letters and the numbers on a product plate example. Worked OK. Didn't try all the punctuation marks though.
In CorelDraw I set a 0.5 mm outline (same as the tool tip) with rounded ends for the text to simulate real output and there's a very good match.
Here's the modified font with s "C" (for Cyrillic) suffix to its name

Please spread the word about your very useful addition to the font file.  

I changed the internal file name to reflect the "0C" name change.  You can now install the .ttf file in your windows font directory and it will not write over my original file.  The new installed file will have the new name.

The .zip file I have attached has the name change in the font .ttf file.

Thanks for the nice job,
George

Hi George, we have a process where we have the information in MS Excel to make an engraving on a plate, and it can export it to a *.cb file (xml code) that can be put to Cam Bam. Now, in Excel, we have a preview of how the plate will look. However, we are struggling with making the Excel font the correct size and spacing such that it will take up the amount of space as in real life and not run off of the field area it is supposed to be in. I have also done the preview in Word, so that your font (1CamBam_Stick_3) can have the size, spacing, kerning, scale, etc adjusted. So, do you have any suggestions on what the said settings should be, or any other way to preview the font correctly in an Office setting?

Thanks,

I may be wrong but IMHO Excel (and MS Office as a whole) is the least suitable program for making such projects. Engraving is not like mail merging a table and printing to a printer.
The stick fonts are difficult for the windows engine to display them by itself because they are very thin.
In my experience I use CorelDraw and set no fill for the font, then set an outline equal to my tool diameter and get an almost real representation of the texts as they will be engraved.

Also I didn't know CB can read geometry from XML format. Will check tomorrow.

Are you dropping the whole "zip" file into the fonts folder, or have you unzipped them and are dropping them in as individual files?   Any .ttf file should be immediately installed in the fonts sub-directory.

Post by: kevwubs on March 01, 2012, 16:18:08 pm
Thanks for your input dragonfly, but the reason that we use Office is for the VBA coding abilities. It grabs the information from the "data" sheet, and makes the code for engraving which is very exact. The issue is that only the bottom right point or something similar can be specified, so we cannot see the actual width. Does CoralDraw have any coding abilities to your knowledge?

Btw, some info for the xml code for CB is here...http://www.cambam.info/doc/0.9.7/cam/CAMTemplates.aspx

Hi kevwubs
CorelDraw also has VBA macro capabilities but I myself have not done much with data merging. Only placing different name and title for about a hundred of people on a corporate business card template and arranging them on a print sheet according to the ordered amount for each card. I've been thinking about trying to write macros to produce G-code directly but never got to the job yet. Maybe because I can export the artwork directly to DXF format which is compatible with CamBam. In a program like CorelDraw you have complete control over fonts, sizes and formatting.
I am afraid I am not able to understand exactly what you intend to do. While CB own format is XML based as far as I know, it means you have to write a complete VBA code to export from Office to native CB XML - with font conversion to curves, etc. The link you provided is about the previous version 0.9.7 where there were templates, while 0.9.8 introduced Styles which work similar but have larger scope. Still I can't imagine how you intend to use them as CB needs the geometry objects to which a given style can be applied.

If your data is not sensitive and if you could give some particular example for the desired plates, maybe we together would be able to solve the problem.

OK, so I just used a trick I've used before on your fonts. I used "remove overlaps" on them. A quick look at the G code file and it seems to not be going over them twice.

It would be really sweet if someone wrote a script to automate that.

Highlight text
convert to polylines
Make a new layer and make it active
remove overlaps
delete text on original layer (or just delete original layer maybe)

Then you could just type away and run the script and have a single pass stick font.

These fonts ARE pretty neat.

I'm using 9.7 still.
Hi guys...

I need to have some single pass cuts, I'm making some engravings in small fonts in foam.  The second pass tends to knock out the details.  Look perfect until the second pass.

I tried the procedure above.  the result is a bunch of polylines, but it appears there are still duplicates of each.  Is that right?  The resulting toolpaths don't appear contiguous in a letter. 



Title: Re: Please Test My Stick Fonts and Let Me Know If They Work For You
Post by: lloydsp on December 26, 2013, 23:01:10 pm
No, after that, all the 'doubles' are thrown away.

I have to ask (not to insult, but because you're new here):  After you did that, did you change the MOp to reflect the new primitive IDs you created when you did the convert and remove overlaps?

Post by: shorton on December 27, 2013, 05:34:52 am
Lloyd, no offense taken at all.  Answers in the context of a complete newbie appreciated.  Not sure I understand your question.  If it means did I regenerate the gcode, then yes, I did do that.  I haven't tried running it on real material yet.  I did look at the resulting tool paths in CamBam and they are no longer one "stroke" moves, but starts and stops apparently in different directions for any particular letter's component.  I looked at it in Cutview Mill and it, too seemed to have a pretty disjointed flow.  This with 0 tolerance....

When I try to remove the overlaps, I do get a question on what tolerance to use.  Not sure what that means, didn't see it in the docs.  So I tried to experiment:

If I set it to 0 I get a lot of duplicate polylines.  When I run the resulting gcode through Cutviewer Mill, I get a lot of repeated movements and it's all disjointed.  I do not get any movements out of the material between letters, it just bulldozes/cuts onto the next polyline.  I am doing the convert to polyline and remove overlaps on a word, not a single letter at a time.

If I set the tolerance to 0.01, I get gaps in the resulting letters.  If I set it to 0.005, I get complete letters, but some letters, like "E", look OK in CamBam, but do not cut properly in Cutviewer Mill.  Dont' knwo if that's the software error or the machine code, assume machine code.  For example, the "E" gets cut as a "P" with an extra foot, top 2 horizontals joined at the ends. 

So, I'm missing something. :(  Help most welcome.

Post by: shorton on December 27, 2013, 05:51:55 am
I did just try a different stick font (Camworks) and the procedure appears to work correctly with it.  It too was cutting between a pair of letters, so I figured out to set my max crossover distance smaller, that seems to have cured that particular anomaly in this font.  Need to go back and retry George's other font, I was workign with CamBam_Stick_8

Any other Stick fonts I can try?

 EDIT:  setting the crossover distance to zero seems to have cured the issue.  The letters draw correctly in simulation now, albeit in an odd order of operations, but one pass per line segment and most letters are done efficiently.  Saw one place where it repeated a spot, but that was minimal.

For other Noobs, for posterity, elaborated instructions are:
Create text, ideally in it's own layer (e.g. layer 1)
Select text
Edit, Convert to, polyline
Create a new layer (e.g. Layer 2) , it will become the active layer (little yellow arrow on it)
Go back and select all the polyline segments (right click on the original text layer (e.g. Layer 1), choose Select all on layer)
Edit, Polyline, Remove Overlaps
I found that for the font I was using, I had to answer 0.005 for the "Cleaning Tolerance" prompt.
The resulting polylines will be placed in the active layer (just created (e.g. Layer 2))
Delete the original converted polyline layer (e.g. Layer 1)
Select all polylines from the new layer (e.g. Layer 2), add machining operation, engrave
Set machining parameters, for me I needed to set max stepover to Zero, to avoid joining close letters.
generate toolpaths/gcode
