Newbie looking at 6040 (China CNC) for polypropylene 15mm sheet

Yea all the people sending me messages said that.
Though they print fine on my 3D printer exporting that way..??



[edit]
Whats with the off center ring on these collect nuts btw?
I have seen it on both this new ball bearing one and my current one shipped with the machine.

I suspect its the way that our CAD systems are 'interpreting' the STL. I know there are some attributes that you can change when you import but not knowing the 'source', we may not know these and this means that the outputted assumption is wrong.

The fact that I wasnt the only person that said this means that there is something not 100%.

What do you use the make the STL?

Exporting straight fro Fusion360 by right clicking my part and selecting "save as STL"






But why is it offset?
Wouldn't it also add vibration to the machine?

It's offset so you can get the collet in/out easily.
If it wasn't offset, you'd not be able to get the collet in/out easily, or you risk the collet popping out the nut when trying to remove the nut/cullet from the chuck.

Balanced nuts are available, if balance is an issue.

Not sure. Perhaps rather saving it as Fusion3D or similar.
