Help me define Santa Claus

[BigC]

I am importing a .stl file into a piece of 15mm stock timber (oak)
So I choose Import, Component 3D Model from the menu.
I just accept all the values the modeling box has to offer (this may be part of my problem)
From there I select the model and go back to my drawing tab and resize it to 70mm wide by 100mm high)
I know that by doing this that my model will increase in height (here lieth my problem)
Then I go to my modeling tab again (choosing the spanner icon) and try to reduce its overall height (I need it down to 6mm)
From which I lose a little definition I think. I may be doing something wrong perhaps at the initial importing stage.
Can this be cured to give me a nice crisp model with a sharp definition at 6mm high.
(Now it may just be a bad model, I don't know).. any help greatly accepted and appreciated as always
Again this could very well teach me something
Regards
C

I don't know if actually matters as I don't do enough 3D to compare but I always do the resizing at the import stage using the XYZ values.

[mezalick]

As Adrian said, I also resize at the import stage.
If the model has any base height ( straight sides) to it you could lower that down before you reduce the shape height.
Hard to give exact answers without playing around with the model.

First, since I've been doing quite a few 3D carving with 3D models, I never accept the default settings for many reasons. You really need to watch several of the 3D tutorials. There are just too many variables to cover and I would be here typing a book just to get you started. One thing I suggest is to download some of the free projects that have 3D models in them and dissect it. Learn how some of the settings in the properties change the model carve. The preview is your friend!

Thanks, Guys. for your replies, your guidance is always appreciated.
I will be watching a lot more tutorials from now on
I went ahead and cut the Father Christmas file this morning.
I changed a few settings in the initial import modeling window and everything seemed fine thereafter
Below are the stats for the finishing pass (Roughing and Profile 3mm Endmill)
1mm Ball-Nose/2 Flutes
Pass Depth 0.25/Stepover 0.08 (8%)
18000RPM
Feed mm/min
Feed 900
Plunge 350
Chip Load 0.025
From the above stats and the images below, Is there anything I could have done differently so show better improvement in the finished piece?
Or is this as good as I can expect?
The whole process took about 2 and a half hours, give or take. It took very little sanding, in fact, minimal and I finished him off with a couple of coats of Rustoleum clear Finishing Wax.
He forms part of a project I'm working on (will post more images later)

P.S. I cannot upload my .crv file. why is this? am I doing something wrong or is it board policy that I dont have this option.

C. ,
Just for kicks and giggles, Duplicate that toolpath with an imaginary(maybe use the .5MMTBN setting in pic for starters)?
Calculate it....then run 1MM Preview.....then doing Nothing else except zooming in a bit....run the .5MM toolpath with the "Show Tool" option unchecked.
IF you can follow where the .5MM is cutting by eye, and you like the small details that sometimes emerge(eyes/hair/buttons/etc.)...then consider running a .5MMTBN?

On Feeds....I usually have my Plunge speed close(or exactly the same) as my Feed speed, and speeds things up in cut times even if you drop Feed for Tinier 3Ds.

3Ds are usually too large to post....most here stick it on OneDrive or such...and then provide just the link to it.
Nice Job!

Woops..here's pic........mainly learning your machine C. IF machine is getting jerky or vibrating at too high a Feed for small stuff...drop Feed/Speed...vibration in machine transfers into the cut.
I forget the thread..maybe "Tiny Chinese tapered ball nose".....more people experimenting and showing results on short set of them(.25-1mm).

Cheers Scott.
Thanks for taking the time out to reply
A couple of Tapered Ball Nose bits are on the Santa List

Ok, I have uploaded the Santa Claus .crv file to Google.
What now?
How do I offer it to others to manipulate and display it in the thread

Big C,

Be careful uploading 3D models with your .crv file. The 3D model may be copyright protected material unless it was something you had created and are freely distributing.

[highpockets]

Sharkcutup is right, posting copyrighted material in any form is verboden. I though I had seen this model some where before. If this is the same one it's not free, but it sure is a good price...

[BigC]

I wasn't aware of this guys, thank you for drawing this to my attention.
For that price, I would rather pay for it, keeping on the right side of things.
It is a nice model.
On that note has anyone had experience of purchasing from Aliexpress etc, I always shied away from using these sites in the past.

C

[highpockets]

I've purchased a number of models from Aliexpress, mainly for 3D Printing, but some for CNC work.

[scottp55]

Sorry for not thinking about that this morning C. Thanks for catching that guys! !
Lousy multi-tasker, and was doing too many things at once

Been trying to think of a similar model that's Public Domain or CC free with attribution.....but a little brain burnt now
All I can think of are Chinese architecture from Di Luo from Sketchfab...topos from TPSully on Thingiverse...Smithsonian stuff and Ted's models at the moment.
Maybe somebody's brain isn't looping like mine, and can make a suggestion for C. ?

Again..sorry C. (I'm usually very good for copyright warnings:(

That file is free an Cults 3d website.

That was where I got it from Mark!
I seen a few freebies amongst a lot of things you had to pay for, I reckoned that these were maybe there to tempt you into purchasing other items and not for ripping people off.
I will gladly pay for models as I have done in the past at Design and Make (which reminds me that I need a few more from that site) so I'm not a person who readily or willingly breaks copyright laws. If its there and needs paying for, I will duly pay up.
