What post processor in vectric vcarve?

(William Kunz) #1

I am testing Vectric Vcarve software and don’t know which post processor to select for outputting the tool path.

I would select GRBL inch or mm, but just guessing as i am a NOB.

There about a hundred choices and i really done have a clue.

Any help would be appreciated.

Thanks,

Bill

I now see that choice, I am using Nomad 883 Pro , but i don’t think that makes a difference as it is all the same GRBL.

Thanks for the quick response.

There is one on the Shapeoko wiki: https://www.shapeoko.com/wiki/index.php/File:Carbide3D-Nomad-Inch.pp.txt

I believe it affords some additional features / support — see the announcement: Nomad Postprocessor for PhotoVCarve, Cut2D, and VCarvePro

and installation instructions: http://www.shapeoko.com/forum/viewtopic.php?f=6&t=7329&p=57904

When I wrote it, the generated G-Code starts with (specification correct) “%” line. If there is trouble using the post processor, let me know and I’ll get rid of it and have @WillAdams update the post processor.

The post processor supports automatic tool length changes, something that the Nomad can do easily but most SO3 are not equipped for.

Those SO3s that are equipped for automatic tool length changes may be identified by?

If someone has a Shapeoko set up for automatic tool length changes they did it themselves and they know, and they need to share / document how they set it up.

Just being sure :stuck_out_tongue_winking_eye:

@WillAdams is the SO3 expert. Correct me if I’m wrong but as I understand it one would know they such automatic tool length change support because C3D doesn’t sell it; they had to add it themselves.

I’m not sure that the SO3 can support it or support it easily. Will?

First off, I ain’t no expert — if I were, I wouldn’t need to crib from all the personal notes which are essentially what the Shapeoko wiki is.

FWIW, I started on modifying my Shapeoko 1 to have a tool length sensor — in theory it’s simple, just a homing switch embedded in the machine wasteboard — all you need to know is its position in absolute machine coordinates and one can then reliably send the machine to it to measure after a tool change — software support is built into Carbide Motion and Grbl (see any video of the Nomad doing a tool change).

One of these days I’ll get the basement tidied up enough that I can get the SO1 and a bunch of other abandoned projects re-started.

I’m trying this postprocessor with my S3 and when I try to run it, Carbide Motion doesn’t recognize it as a file. I’ve opened the file after postprocessing and it appears all the information is there. Is there a tag or command that is needed for it to be recognized?

What extension is the post-processor assigning to the file?

.nc Perhaps I need to re download the file and try again?

.nc is the file extension used by Carbide Create, so it shouldn’t be that.

Open the file in a text editor to verify that it’s G-Code?

Are you sure that file permissions allow you to access the file from Carbide Motion?
