F-Engrave help...clean up pass is not cutting in correct spot
Hi,
I just started my first try with fengrave(v1.55)...i am doing a cleanup pass after my intial vcarve and for some reason is does not line up properly with the first v cut pass
it looks almost like it needs to offset more by the amount radius of the bit...
i overlaid the cleanup pass in magenta on top of the vcarve for reference to see what i mean. It needs to move over in x and y, you can see that the gap on the bottom and left side is not correct. And also the angled magenta lines did not retract when it traveled those so it cut through all of that.
I cut my first vcarve pass, loaded the clean up pass leaving my x and y origin untouched and simply rezeroed for the new tool.
has anyone else experienced this?
Re: F-Engrave help...clean up pass is not cutting in correct spot
That looks really bad. Can you please send the g-code to the e-mail address in the F-Engrave Help Menu so I can take a look at it?
If this is a repeatable problem it would help a lot if you could generate similar g-code and save it with the "Suppress Comments" option unselected in the F-Engrave "General Settings" window. This will save all of the settings in F-Engrave as comments in the g-code file.
It would also be benificial for you to download the latest version of F-Engrave. F-Engrave Download

thanks for the quick reply...i just noticed there was newer version and will give that a try also..not sure if its a version issue?
will email you the code
thanks
Re: F-Engrave help...clean up pass is not cutting in correct spot
Hi,
Just downloaded new version and tried it and it looks fine now...so maybe just an issue with 1.55 then?
I will do a test piece with the new code and see...but it looks like it should be good.
thanks
Re: F-Engrave help...clean up pass is not cutting in correct spot
Is there a way to get fonts with single pass, and also with an image? If I remember correctly, if I import a bmp of a circle O, F-engrave will trace both the outer and inner diameter. Thanks.
For example, I also just noticed that it appears the cutter here is not lifting between two separate objects (but that might be my free J-viewer software). I have drawn two squares, one solid black and another as an outline.

I didn't really expect the version to make a difference... After your previous post I went back to look at V1.55 and indeed the cleanup operations are royally messed up. I have done a lot of work with the latest version V1.59 so I am confident the problems have been resolved.

Most fonts are outline fonts and If you bring in an image F-Engrave will trace the outline. The v-carving option works well with these types of inputs.
There are some "stick fonts" that are defined as strokes rather than the outline of the characters. There are a couple of links ant the bottom of the f-engrave web page for these fonts. Stick fonts work well for engraving text.
Hershey Fonts (CXF)
CamBam Fonts (TTF)
If you want to cut single lines of an image you need to find some way to convert the image to single lines and bring it in as a DXF file. Someone sent me a link to a program that would convert images to lines but I don't remember what it was called... I will dig around to see if I can find it.

The g-code you posted does include lifting the the tool between cuts.
Re: F-Engrave help...clean up pass is not cutting in correct spot
Thanks. I understand how it works, and it's fabulous!. The fonts are great too.
Re: F-Engrave help...clean up pass is not cutting in correct spot
Here is some information that was sent to me regarding an online tool to convert images to single line vector format (suitable for engraving). I have never tried it but Rod had good success with it.
Free Online Raster to Vector Converter

Free Online Raster to Vector Converter
Pick:
Centerline
Adjust smoothness
Output to DXF
Click Trace
Save DXF
Import DXF into F-Engrave
I was able to upload an A and it was turned into 2 operations with only 1 Z lift.
