You are reading old posts that were at best inaccurate. Yes, you can
import/export data in Fusion. And they do limit you to "only" 10 open
projects at the same time. So you have to close one to open an 11th one at
the same time. Go to the Fusion360 web site for the correct information.
That is what I just read in Dave's post
The free license for Fusion is different, but of all the free CAD/CAM
systems Fusion360 still has the best feature list. and the best support.
I'll check what the licenses are. Free of course is always good, and of
course comes with limitations. However, it ia a hobby that I play
with/explore so now and then and don't want to dump mayor money in (the
mill and lathe were given to me.)
How do you convert your FreeCAD data to G-code? This is the biggest
problem I have with it, how to move the design to a lathe or mill. I only
see a path for that if doing 2 1/2 D milling.
well, with freecad you can set up a job, and create a path within that
job. You can select for what application/environment you want to
create the g-code/path and linuxcnc is an option. (However I do see that
sometimes these paths are not 'optimal' and sometimes even wrong. But
again, hey , it's free, and with tinkering I can get around it. (Of
course a 'real' machine shop would never do that, of course pay for
good quality software as an investment. With me it is not an investment,
it is just money spent.
The g-code path is a file that you can 'export' (I do that either with
nfs, or even ssh/scp, so it's on the machine that runs linuxcnc. In
linuxcnc with axis I just pic it up, run it as a "simulation first and
if I like what I see try to make the part.
Linuxcnc is cool, it can do a lot more than I (as a hobbyist for sure)
would ever need. Also, I like to tinker with electronics, the machines
themselves, and this forum is great for that.)

Hi Chris,
well, I am only looking into something different for making some parts
on a lathe, I looked at fusion360, but what I hear is that you can't
'export' projects, or import, and also you can only have a few. Not
that I do a lot of work, but it seems to be a hassle.
I have a sherline (rebranded to Paxton/Patterson mill, so that is 3 axis
as for now).
I use freecad for the mill, and that's more than I'd need already. I
was suprised that it doesn't generate code for lathes (although, I have
the impression that people have been working on it, but not seen
something really yet. (also I mght not know enough about machining, to
understand why it is difficult to create something for a lathe, but not
for a mill?)
There's that gentleman here that has some modules with an interface
(sorry man forgot your name), but somehow I never got that to work in
linux cnc. (No movement, maybe I did get parameters wrong, maybe not
setup right, dunno)
So I am still looking, it is fairly easy for me to make thing is freecad,
Also, I don't have a "professional machine shop" so I am not looking to
spent significant amounts on software.

The free Fusion360 license allows 2 and 3-axis milling, adaptive

and turning. This is likely enough for most people.
What you can't do is 4-axis and 5-axis milling. To enable that you do
have
to pay for a license
more info here: https://www.autodesk.com/products/fusion-360/personal
The other CAD options completely lack any build-in CAM functions. So it
is
pointless. Yes you could design using CA then hand-code you g-code but
then you loose the guarantee that the g-code follows the design because
there is an "air gap" in the work flow and it is VERY hard to make
organic
looking shaps with hand made g-code.
My criteria for choosing software is "Could I use it to make a battery
operated drill with the over-molded rounded case that fits your hand.
Fusion360, even the free version would allow this if you split the case
laterally to make to halves that assemble together. You couldn't use
the
free Fusion for a one-piece model of a drill because to mill that you'd
need at least 4 axis
If you do need better CAM to run a more complex machine tool and you are
on
a limited budget. There is a way to get SolidWorks at no cost if you
are
an EAA member. SoldWorks is the only other CAD I know of that includes
CAM
and can be had for zero or very low cost.

Hello,
I have been busy for a while with that pay check thing, and didn't have
much time to look into creating g-code, that I can use in linux cnc
for a lathe.
Is there anything "new" yet? I was thinking about using fusion360, but
I heard that is on it's way out for even a reasonable hobby priced
license
are there any alternatives?
I found this video, and was wondering how well this works, has anyone
done this?
