After having difficulties carving a sculpture on rotary I decided to scale back and just design a simple file with easy geometry to check measurements and so on.
It has been quite disappointing, to say the least.
I frankly want to blame Vcarve here, I think the software might not be up to the task, or is it me?
There are a lot of unfinished areas.
There are tool marks left from the roughing tool path.
The round base is oversized by 0.9mm.
The cuboid is oversized by a similar amount.
The truncated cone has a lot of tool marks from the roughing tool path.
The Cylinder on top is oversized by about 1mm.
It appears that most areas just got touched by the roughing tool path, the oversizes areas would make sense then, I had the machining allowance of the roughing tool path set to 0.5mm
It looks like Vcarve did skip a lot of areas in the finishing tool path.
I roughed out with a 6.35mm end mill.
Finishing tool path 6.35mm ball end, then tapered end mill R1mm.
I used the touch probe to set the Z after every tool change, so that should not be the problem.
I’m not sure of the reason for your animosity toward VCarve, but I suspect it may be misplaced. I have rendered the milling preview for your file on my machine, and VCarve does not appear to have any issue with the defined tools or toolpaths. It also does not appear to have “skipped” anything of note.
Having results that differ from the preview usually indicates something lost in translation. Most often, this points to an issue with machine settings, material set-up, probing, or a bit mismatch — using a bit other than what was defined in the software, or incorrectly defining bit parameters in the software. We could also add post processors to that list, but it’s my understanding that others are using the rotary PP successfully.
The more I think about it the more I am sure it is Vcarve.
Just playing around with different sets of tools creating different toolpath. The finishing toolpath seems to ignore some areas. However, those areas change depending on the tools I chose.
I think Vcarve rotary is probably somewhat neglected.
Maybe there are not enough users.
Rotary is an illusion. The radial model is “unrolled” into a planar model and processed like any other single-sided 3D carve. You can actually see this in action while you run a preview.
I appreciate all these postings concerning the rotary attachments and capabilities with the buildbotics so to speak controller my question here is for the rest of us to learn more of others can post pictures or videos or explanations of what they are doing with their rotary so we can learn more grab nuggets from you thank you
but i am finally setting my rotary up for elite foreman. I purchased VCarve Pro, i had a bunch of statuettes i’ve been saving for the rotary. well, i started uploading them on vcarvepro and just realized that it isn’t able to fully carve out all the crevices on the model.
this is my question. how intricate of a design has anyone done, or how intricate of a design can this rotary do? I realized that the rotary will still only carve straight up and down and won’t get the space behind a raised finger for example. Not sure if i explained that well, but in know for regular bas relief 3d carving, a full figure person, the carving wont carve under their arms for example, i’m seeing same applies for the rotary…
I know from practice the resolution of the model and the speed of the spindle and the amount of step over on the bit have a great impact in the quality of the project.
One of the biggest problems is under cuts and how to avoid them
If you can’t then you’ll need a 5 axis machine with a rotating spindle
