G-code failure help needed please

[cropwell]

Hi,

Inkscape is free, but I find it shit for creating dxf files. There is Draftsight for nowt, Libre Office have a CAD program. To get to Gcode you will need something like CAMBAM or G-Simple, but I have never used these, I use Estlcam, which is fairly cheap.

With your image, you will need to trace it with Inkscape to get to vectors so you can create a file for further processing. If I were not unwell (hot weather and whisky ) I would be happier to help you.

The Sign you want doing is the easiest, but what font and what DOC's. I'll PM you soon.

Cheers,

Rob

Hmm,

I'd hesitate to send you any code as what my software generates is very unlikely to work on your engraver (without me knowing exactly what post processor you use, where you're zeroing off etc. etc. - it's a bit of a minefield, best not go there!)

What I will say, though - is that the image you uploaded is far from ideal in terms of getting enough information from it in order to generate an engraving that's going to look any good...

This is likely to be a hiding to nothing, but I've poked it around a bit and improved the contrast for you so now it looks like this:



It's still not great, but the attached .pdf (look for it at the bottom of this post) now contains the vector (or line) information that your software should recognise and be able to use to tell the machine what it is that needs to be cut...

Wal.

Hi Wal, OP seems to use Mach3 set up in metric. I have sent him some code to play with, just to prompt up the problems. So far it looks as though he has hit the 500 lines demo limit, so if he wants to continue, he will need a licence. At least now he has some code to carve a sign for his house, and if it doesn't work we will have a chat by phone or email to get him pointed in the right direction. That way we can get the dross of the problems sorted before reporting back to the forum.

When we have the machine set up, I can send him the face on Gcode. Thanks for doing that, it look great and it saved me a bit of trouble farting about with Inkscape Trace.

Cheers, Rob

I have the machine setup and working OK now, Will you be able to send me the g-code so as I can produce the image Joe

[cropwell]

That's great Joe, how are you getting on with the house sign gcode ? When I know that that works, I can do the picture of Eamon, otherwise there will be some tweaking to do.

Also, do you want the picture the same size as supplied or scaled to a particular size ?

Thank you Wal, The improved image looks great and I hope to use it asap Joe
