My first 3d project
I recieved my cnc last week and have become very comfortable with vcarve pro so I decided to jump into cut 3d today. I purchased 20 images off of ebay and decided to machine a flower top in walnut. Ive been using my sanding mop to clean it up but it needs more work. When the machining was done decided it needed a base so did a simple profile in vcp with a lid lip and ended up with this little round box. Ive got a long way to go but vcp and cut3d make life easy.

Re: My first 3d project
Will decreasing the step over elimnate the cutter lines? I used the default settings in cut 3d for a 1/8 th ball nose.

Re: My first 3d project
Very nice, and the lightning is cool....
To answer your question, yes, reducing the step over will reduce the cutter lines BUT it will also increase the cutting times....It's a real balancing act.
Keep up the good work.

Re: My first 3d project
Thanks Michael not to worried about machine time as a better finished part saves me time sanding. I will make another one tommorrow and reduce the stepover by half. Heres a lexan carving I did last week for the owners of a glass company. Hes planning on using my shop for future projects if he likes what he sees so these are freebies but hes supplying the lexan for me to ge the experience so its a win win. My machine is only 7 days old and its alrdy paying for itself.

Re: My first 3d project
Use a stepover of 8 - 10% that will give you a smooth finish on your ball nose bits.

Re: My first 3d project
The common step over seems to be around 9% ( Tony you posted before I could add mine but we are in agreement....
As for the Lexan, one note of caution.
The reason Lexan is used to replace glass is because it’s “ flexible “
I did a fair amount of installing Lexan on church windows to protect them from breakage.
It works well ,,but it’s also “soft”.
Cast acrylic would be a far better choice to produce a quality.
But I also know, what you get is what you have to work with.
I have run the same file in the reverse direction to clean up the leftovers.
Best of luck on the venture.
Post pictures of your progress.

Re: My first 3d project
Thanks for the info on the stepover thats exactly the information I was hoping to get. The lexan tip running in reverse was also interesting could you explain the process how do I tell vcp to run in reverse for cleanup?

Re: My first 3d project
It's not so much as cutting in reverse but rather cutting at another angle.
I would recalulate the same file and choose the option to alter the direction of the finish cut.
Michael
PS this is for the Cut 3D part. In VCP you could maybe use the Pocket or Profile toolpath and use the climb or conventional toolpath option.
Or even the raster option and set a new angle for cutting.
