/Having trouble with V-carve

Good day folks,

I have been having an issue with v carve for some time now. My projects that contain v-carve toolpaths now take an unbelievable amount of time compared to before. For example, a project that used to take me under 10 minutes now takes over an hour. speeding the feedrate will not change anything, and that is because it does almost all of the carving in plunging. The machine will trace my design by plunging a million times and making small dots rather than following lines/vectors. The results are as good as before but now I have to run the machine forever for simple designs. I just ran a project that Create estimated to take 11 minutes, Motion estimated 12 minutes and it took almost 2 hours. Time was barely going down in Motion. Not sure if maybe there is some sort of glitch in either Create (V7 build 778) or Motion (build 640). I recently updated both in hopes that it would fix the problem. Has anyone else experienced this? It is becoming quite frustrating.

Can you post an example?

I can’t upload a video of what the machine does. But here is a few screen captures that show the toolpath. This snowflake is about 10mm in length and took about 5 minutes to carve. It shoul have taken seconds without all these unnecessary movements.


Try the new v8 beta:

which should handle this sort of thing better — if you find a file which doesn’t work well, post it to that thread and we’ll do our best to look into it with you.

Thank you,

Just installed V8. Haven’t ran the program yet but it does seem to cut down on unnecesary movements a lot.

Cheers

Another good case where none of the “pick” moves are necessary, and it would look better & be more efficient without them. :wink:

Unfortunately, the computer can’t read minds. The only thing it has to go off of is the shape provided, and since the ends of the snowflake are not perfectly round, picking is required.

I can’t figure out why you would say it’s ‘not required’. If it didn’t do it, then the result wouldn’t match the shape provided.

Thanks for the response.
I get what you mean. However, this photo should put things into perspective. This snowflake is so small, these movements could not possibly make the slightest difference to the shape as it goes far beyond the level of precision that you’d be able to see. So yes I do think at this point they are unnecessary. Carbide V8 did remove most of that and V7 didn’t use to do it so much.
This took 5 minutes to carve and is not viable.

It doesn’t need to if there’s an option to select your desired result. There are many cases where the vectors are not perfectly prismatic but the maker doesn’t need the path to perfectly match the vector. A rounded font -vs- single line font for example. Traced geometry from a lower resolution image. Any curve that’s made up of a bunch of short straight line segments.
In many cases, the radius of the cutter is ‘good enough’ or even better than the picked out result, and it takes less time.

Ideally, that star could be made with a contour path on open vectors
