3D cut issues on curves
Re: 3D cut issues on curves
The Modeling Resolution was set to High 3x slower, also could have went with Very High 7x slower. In the pic of the Roughing preview, the jagged edges started there and never went away with Finishing. If there are more hidden Resolutions other than Standard, High, Very High, I don’t know how to access them.
Re: 3D cut issues on curves
I kept an unmachined area on the workpiece to place touchprobe, and yes, re-zeroed each bit when changing.

Re: 3D cut issues on curves
To access increased resolutions hold down shift when you create a new job.
Are you absolutely sure the artwork is high quality?
There is a lot of junk out there. It is the wild west with some of these guys.
As a general rule of thumb increasing stepover beyond (8-10%) on a Finishing yields a less than desirable end result.
Requiring LOTS of sanding actually wasting more time and or recarving. I know a guy this happened to.
On a larger project you should go up in bit diameter to hog out the area faster not increase the stepover.
Of course this will smaller bits utilizing REST machining option or multiple finishing toolpaths will progressively smaller bits.
Don't take this the wrong way.
Are you using the right bit?
there was a case recently where the OP labeled the bit as 60 and actually used a 90 degree bit.
It happens to the best of us. I can tell you horror stories about my misadventures.

Re: 3D cut issues on curves
It's really hard to see any details in those pictures. It would be better if you took screen shots using the Windows snipping tool or similar rather than taking a photo of the monitor.
If you don't know how to do that then what would really help is to run all the toolpaths in preview and then use the Save Preview Image on the toolpath preview form and then upload that file.

Re: 3D cut issues on curves
No offense taken. I am 100% sure I had the correct bits. The design was purchased on Etsy from All D-N-J-Creations-LLC. I've blown up their display images and see what I expect to see, smooth contour, not jagged like mine. I looked and standard setting for my IDC Woodcraft 18EM is 40%. The IDC 18BN standard is 17%, I know I should have set it to 7-8%. The 18BN Taper .045 tip was set at 17%, standard is 8%, know I should have done that as well. Maybe I dont have a realistic handle on what amount of time a given tool path shoud take.Note, this is 24.5"x16.0" a fairly big sign. As carved:
18EM 5:30
18BN 11:30
18BN Taper 4:30
Re-run all toolpaths with appropriate stepover
18EM 5:30
18BN 24:30
18BN Taper 045 8:00
After re-running all toolpaths with 7-8% stepover, the jagged edges still there. Stumpped, other than takes twice the time. Maybe the design is meant to be somewhat jagged

Re: 3D cut issues on curves
As I said on the previous page the pictures that showed the actual model show it to be really rough and that toolpath preview looks to be an accurate reflection of the base model from what I can see.
Some of the other pictures of that design on the etsy page aren't done as 3D, they are done as 2D pocket/profile cuts and v-carve toolpaths. That's how I'd do a design like that as well. It's not really a 3D job.

Re: 3D cut issues on curves
Thank you all!!!! Don’t waste anymore time on this. I wondered about pocket, VCarve strategy, etc. This is all part of the learning curve. Thanks again to all! Will try some other scenarios.

Re: 3D cut issues on curves
Cut .125" deep Pocket Toolpath with three different size endmills and then for the outline of the text 30 degree V-Bit on the text vectors.
Oh and I eliminated all the empahsis Vectors around the pistol.
Added the Emphasis Vectors
No need for a model!!!

Re: 3D cut issues on curves
Shout out to "sharkcutup"! Took your advice and approached the design from a Pocket/VCarve strategy. Looks like I think it should and go from approximately 16+ hrs of carve time to <6 1/2 hrs. Thank you, I think things out in a practical, logical way, but this CNCing is a new challenge that I embrace and need to lean on others to point me in the right direction! Very glad I joined the Vectric Community and hope someday I can contribute knowledge to others (pay it forward) as others have done for me. Tanks again to everyone!!!!

Re: 3D cut issues on curves
It is best to post images rather than photos using the Snipping Tool
