well, I got a lot of good information from this list,  also where I was 
"rebuilding" the mill and lathe.


(Phill Carter helped my out A LOT)


There are a bunch of utilities out on the web, that let's you drill 
holes in patterns, make pockets in certain sizes/shapes etc.

This is potentially very easy with G72. You just need to create the

rest.

Re: [Emc-users] CAD for parts to make on a lathe

[Chris Albertson]

If learning is the goal.  I think the route is to first hand-code the
g-code files.   Then if you want to learn how to connect CAD models to
g-code you have no option but to get a CAD system that has native CAM for
lathes.Fusion360, Solidworks, and Inventor are options but OnShape and
FreeCAD are non-options.

G-code for a mill is so different from g-code for a lathe that you can't
use one for the other. The tool libraries alone would be very different.

Solidworks is free for EAA members.  That could work.  Or if you don't care
about saving your work, Fusion 360 for free is still a valid opinion.
Parts designed for lathes are very simple so who cares about saving the
design to .step files?   Just use Fusion360   (or Solidworks)

Hi Chris,


well, basically I just want to learn how to use them, by making some 
things I actually have a use for. For now on the lathe, I am trying to 
make a little shaft for a project.


Why use CNC?  well, because I want to learnhow to use, do lathe work, 
using CNC.


Well, I do/did build robots/rovers and such.  and dozens, no, but maybe 
3 shafts that are the same, and if one breaks or so, make another (the 
same) one



So really it's about me wanting to learn how to do it, preferably with 
something like freecad or so.

This giveaway happened with Simulink. Got the feeling they forgot about both 
control theory. For me it make no big difference if equations is drawn as

What they get is sales of the full product.   Every new aircraft company
starts as a small project by some EAA member.   (Yes, I'd bet that EVERY
person working on a new small plane is a member.)  Then the project turns
into a company and they need to upgrade their license.   DS is "fishing" by
casting a wide net hoping to capture new paid users.

This is the same reason they give away the product to students.  They will
graduate and need to convert the free license to a paid one.In a way,
these airplane projects "graduate" too.

When you sign up as an EAA member you will get a monthly print magazine and
in it, you will see there must be hundreds of these small
aircraft companies.  It is a big industry when you add them all up.

[Chris Albertson]

Have you been an EAA member?  Many people here would like it.  There is
just a ton of information and articles and books they produce on
metalworking and paint and riveting and welding and so on.  Yes, it is all
aircraft related but it does have a wider application.

I'm sure that almost everyone on this list would not mind learning a little
bit about aircraft fabrication on wood, composite or metal aircraft.

The EAA is a not for profit organization and can use your $60.  I am pretty
sure they don't care why you joined,

Despite what people are saying, Fusion isn't a web-app, and the vast
majority of the computation is done locally.
Not that the postprocessor files are stored locally, for example. As
are the thread tables etc.

All that is done on "other people's computers" is file conversion and
file storage. And I think that is intended as a feature to allow
working on the same model from different locations and by more than
one person.
You can save the f3d locally. But I hear rumours that F3D is more of a
memory dump than a file format and might be very version-dependent.

Add a STEP importer to PyCAM?

PyCAM came within a whisker of moving in to the LinuxCNC project. It
still might.

Joining EAA just to get a discount on SW seems somewhat dishonest to me.

Then the rest of the gnashing and wailing of teeth seems to be
suggesting swapping to something much more expensive than
paid-for-Fusion just to kick back at Autodesk.

I got burnt by Alibre some years back with their entry level version.

I would never trust them again.

Re: [Emc-users] CAD for parts to make on a lathe

[Chris Albertson]

As I just wrote, after looking I find the only affordable CAM systems that
can do more than 3-axis are Fusion360 at $500 (on sale now for $270) and
Solidworks which id free with EAA membership.

2.5 axis systems are easier to find and it seems FreeCAD does that.

The free version of F360 is now to crippled to consider.

Re: [Emc-users] CAD for parts to make on a lathe

[Chris Albertson]

I just checked, the $199 version of Alibre is almost useless.  It does not
even have Bolian operations and no CAM.At $750 you get a 2.5 axis CAM
system and prices go up higher for more  features

FreeCAD does as much as the $750 Alibre.

To do more it seems the best option is either $500 for Fusion360 or $60 for
Solidworks.

Re: [Emc-users] CAD for parts to make on a lathe

[John Dammeyer]

I'm not paying $1000 year for AlibreCAM but then I don't have more than the 4th 
axis package nor the lathe feature.

The basic AlibreCAD comes with a simple CAM module.I doubt the low end 
Alibre for under $200 has CAM since that comes from MecSoft.

MecSoft also has CAM support for RhinoCAD and for their own Visual CAD/CAM
https://mecsoft.com/visualcadcam/
Starting price is $595.  I've used the VisualCAD.  Not a lot different from the 
AlibreCAM since the basic engine is the same.

Re: [Emc-users] CAD for parts to make on a lathe

[Chris Albertson]

In your case, you might want DS Solidworks.  I've been reading CAD system
specs and web sites for hours now and the ones that do have CAM are
limited.  Except for Solidworks.  They use SW to make things like rocket
engines for SpaceX boosters and car plants at GM.

SW can drive a 5-axis mill but I don't know what limits are.  I know it can
do 3+2 milling

FreeCAD is limited to 2.5 axis and some limited 3 axis milling.

OnShape requires 3rd party CAM solutions.

It might be worth buying an EAA membership then enrolling in the
"Solidworks University" program.  But it would take months to work through
all their training materials.

How do you generate gcode from Alibre? I found
https://www.alibre.com/ecosystem-cam/ and AlibreCAM appears to be $1000/year
to over $21,000. I can afford $199 one time but an annual licence costing
thousands is not in my budget!

That's one that's going to hit me.  I always expected the free version to 
disappear, so I never invested much time in the CAD.  I've been using F360 to 
import STL files and export them as STEP/IGES.  I'm not sure how I'm going to 
do this now.

The other killer is 4th and 5th axis CAM.  I can still import STEP and output 
3D gcode (and turn), but I just started collecting parts for a 5th axis 
trunnion for my hobby CNC router.  :(

Re: [Emc-users] CAD for parts to make on a lathe

[Chris Albertson]

Fusion360 just made changes that in my opinion kill the product for
personal use.  You can not save your work locally as a STEP file after
October 1, 2020.So download your stuff now.

OnShape and Solidworks look like good options.

Solidworks is used for thinks like rocket engine design at SpaceX and for
building cars at GM.  You are not going to outgrow it but may not need it
either.OnShape does not have native CAM.  I assume people on the LCNC
list want CAM.

One opinion is to just pay for Fusion360.  It is on sale now for about $270
but will go back to $495/yr at some point.

What is REALLY needed is a good open source CAM system that accepts .STEP
files from any CAD system.

The feature they are taking away is the ability to save your files to an
industry-standard STEP file.  Unless you pay for a license.

You have until Oct 1 to download your files.

I read that the EAA server crashed recently.   Apparently many Fusion users
are moving there.

I ran Fusion for over a year on the free "startup" license until it
expired. I had downloaded my files to local storage so I had them to use in
the future. I later returned to Fusion on a monthly basis to continue some
work and found all my files were still intact when I reactivated my

Or time. picked CERN as paying sponsor, would guess peopple at CERN would make

Seems to be good business to sell support, happen to know it happen to know if 
it happen wooden head get support while others have to get by without, would 
expect this business model would be particularly good then selling consulting 
work.

Less money need to be spent if using open source, drawback may be software not 
equally good although differences is shrinking and some time need to be spent 
on improvements which will also benefit others.

Re: [Emc-users] CAD for parts to make on a lathe

[Chris Albertson]

The problem is keeping Fusion 360 going does requires about 40 full-time
staff.  Fusion 360 has about a 6% or 7% market share but the vast majority
of users are not paying.The company can afford the loss because they
also sell Autocad.

The problem with open source CAD is you need a sponsor.  The best example
is when KiCAD picked on CERN (The big European physic lab) as a paying
sponsor.   The quality of KiCAD jumped upward dramatically when they were
able to hire full-time people.

Also, professional users want professional-level support.  You can be
paying a $120K/year engineer to post questions on public forums and hope
some other engineer is able to help.   It is worth paying for tech support
if your users are on salary.

Many people here, I assume have never seen good, first-tier technical
support.   I used to write software and many times I'd fly out to
the user's site in Europe, the US, or Korea and just talk to them about
what they needed and watch them work.  Our customers paid 7 or 8 digit
prices and got what they asked for and quite a lot more.

Even open source projects need money coming in.  The big ones find ways to
generate income, usually by consulting work.

They need some way to earn money as everyone else but it's not possible to 
write some software and live on it forever, over time it is leaning towards 
open source. Maybe with some luck it will be possible to work shorter days then 
there is less need to write new software and other development, though still 
need to know how to use it.

[dave engvall]

Chris,
You might try Synergy, does the whole ball of wax. Not too expensive. 
Takes time to learn. Parasolids based. 2D, 2.5D, 3D, wireframe, solids,  
turning and probably something i missed. Unusual feature is extrusion 
screws.
Runs on linux; will run on Windows but you lose a few features. Has a 30 
day free demo.

As far a photoshop; gimp is pretty good but maybe not so easy to learn.

YMMV

Re: [Emc-users] CAD for parts to make on a lathe

[Chris Albertson]

I just posted a legal way to get Solidworks for $40 which is close enough
to free.

Back to Fusion360.   You should not have lost your drawings.   They can be
saved locally as .STEP files.  Step files are universal and can be imported
to just about any CAD system.

Yes they do charge for Fusion if you make money with it.  The threshold
used to be $50K then that changed to a $100K threshold but now they judge
if you are still in "startup" mode or if you are an established business.
  The paid license is only $495 per year and if you are using Fusion to
earn $100K you can afford $495.

As was expected, I believe AlibreCAD was always designed to be sold.  And that 
they did to3D Systems and it became Geomagic.  The advantage with Geomagic is 
that it allowed USB based dongles for the license and it could import 3D 
slicing files.  The Mecsoft changed over to their standalone package for a 
while.

Ultimately, Geomagic languished with very few upgrades or bug fixes and the 
original authors bought it back.  The dongles became useless and MecSoft 
reintegrated AlibreCAM into AlibreCAD.

I now have the 4th Axis version of AlibreCAM (MecsoftCAM) and just received the 
invoice for another year for $400.  I think I'll pay it for one more year while 
I wait and see how other CAD/CAM systems play out.

This stuff isn't cheap but like anything from a musical instrument to ballroom 
dancing, it requires constant practice to stay competent.   And if you can do 
one project for someone that pays $400 for machine time etc. then consider the 
CAM software free.

I had the same issue with Alibre once, so don't really trust them either.

But saying "Don't use CAM, use hand-coding" seems a bit of a stretch.

Though the internet is aflame with news that Autodesk have announced
that they have turned evil (as predited) with the F360 license.

In reality I think that they are just trying to make the delta between
free and paid bigger to encourage more paid subscriptions. But till
things settle down I probably wouldn't suggest getting too tied-in to
F360.

Re: [Emc-users] CAD for parts to make on a lathe

[Rafael Skodlar]

Hi Ron,

Here is how I searched for what you are trying to do if I understand you 
right.


CLI is the best way to manage software in my experience. I rarely use 
GUI utility even in Kubuntu workstation.


As a root in my Kubuntu I have the following aliases:
alias acse='apt-cache search '
alias acsh='apt-cache show '
alias agar='apt-get autoremove'
alias agd='apt-get dist-upgrade'
alias agg='apt-get upgrade '
alias agi='apt-get install '
alias agr='apt-get remove'
alias agu='apt-get update '
alias asv='apt-show-versions -p'

I have a lathe too, that works with CNC linux, but noticed heard, that 
you can't really  make parts, or g-codes, with it for a lathe.


So for program or related library search I do it this way:
* command
acse lathe

That returns more or less related lines with a description like this:

dxf2gcode - prepares drawings of parts for automatic machine tools
php-tcpdf - PHP class for generating PDF files on-the-fly
ruby-ami - Ruby client library for the Asterisk Management Interface

next command will tell me more about some related package:
acsh dxf2gcode

Homepage: https://sourceforge.net/p/dxf2gcode/wiki/Home/
Description-en: prepares drawings of parts for automatic machine tools
 This program reads 2D mechanical drawings of parts to be fabricated
 and produces G-code tool movement instructions for running on automatic
 machine tools (CNC machines) such as milling machines and lathes.
 .
 This is a graphical CAM (Computer Aided Manufacturing) program.
 It accepts input in DXF, PDF, or Postscript format.  It supports 
milling, drilling, and turning operations, as well as work-holding tabs.


I did not include lines with checksums etc. to make it clearer here.

What wold be a good choice for designing, simple, parts for a lathe, 
that will create g-code for it?


"It accepts input in DXF, PDF, or Postscript format.  It supports

That's impressive assuming it work as described.

-
To install the program I would use the command:
agi dxf2gcode

After that you can execute it from CLI or GUI menu.

Of course there is option to install as a unprivileged user:

sudo apt install dxf2gcode
but I'm trying to save keyboard keys ;-)



thanks,


Ron


I have not tried to install and try this program yet but might do it in 
one of my VMs later.


Searching for CAD I received one related app among other things:
solvespace - Parametric 2d/3d CAD

If the output is too long you may narrow it down with
acse cad | grep CAD

here's a description for solvespace:

Homepage: http://solvespace.com
Description-en: Parametric 2d/3d CAD
 SolveSpace is a parametric 2d/3d CAD program. Applications include:
 .
  * modeling 3d parts — draw with extrudes, revolves, and Boolean
(union / difference) operations;
  * modeling 2d parts — draw the part as a single section, and export DXF,
PDF, SVG; use 3d assembly to verify fit;
  * 3d-printed parts — export the STL or other triangle mesh expected by
most 3d printers;
  * preparing CAM data — export 2d vector art for a waterjet machine or
laser cutter; or generate STEP or STL, for import into third-party
CAM software for machining;
  * mechanism design — use the constraint solver to simulate planar or
spatial linkages, with pin, ball, or slide joints;
  * plane and solid geometry — replace hand-solved trigonometry and
spreadsheets with a live dimensioned drawing.

The best test would be to see how the generated (awful) G-code would 
behave in LinuxCNC of course.


This also reminded me about a book I bought in 1990s: The CNC Workbook 
(Addison Wesley 65600) that came with a floppy for DOS program. I 
misplaced the floppy but remember there was a program to simulate CNC 
lathe. Very good book with labs to learn CNC basics.


Good luck,

Re: [Emc-users] CAD for parts to make on a lathe

[R C]

well, I was thinking, this morning  that if you can make a part by 
rotating it, in freecad, you can also extrude it a bit and then create 
code for a mill.


If the steps/overlap would be small, then  one would end up with 
something that can be used on a mill, with some adaptations/translations?



Of course ..  that idea probably  is asking for trouble.

Chuckle.  As a CET I had to ask, but forgot the smiley, my bad.  As a 
side comment, I have around a ten pack of the 2M542 drivers in service, 
the first 7 pack for over a decade now, zero failures.

I actually read something about how to do that, but one would need a 
plugin for the path workbench, and read is was not that reliable?


I did play with rotating parts etc in freecad

I have a lathe too, that works with CNC linux, but noticed heard, that

Also used Freecad a little bit. Suspect rotating a sketch is a good or very

Hi Andy,


that sounds like something I had in mind, well, either that or just

Things I am planning on doing on a lathe are rather simple, I want to 
make a little shaft with different


diameters in some places.

No. Which looks like a deliberate choice as it _does_ run natively
(and nicely) on OSX.

It makes decent G-code, but I rarely bother.

For almost everything I make on the lathe I work _at_ the lathe and use:
https://forum.linuxcnc.org/41-guis/26550-lathe-macros?start=0
Which is a lot like using a manual lathe, but with a hyper-capable power feed.

For example, making an ER20 collet last night. I used "face" on the
end of the bar. Drilled a hole with the tailstock, then used a "bore"
cycle to make a counterbore for the (special) nut, then another boring
cycle with an 8 degree taper for the collet socket, followed by a
threading cycle to finish it off.

Also, the master branch contains the G70 / 71 / 72 lathe cycles:
http://linuxcnc.org/docs/devel/html/gcode/g-code.html#gcode:g70

Basically you define the profile with G1, G2, G3 lines and arcs in a
subroutine and LinuxCNC makes that shape.

The documentation for the actual implementation is rather poor. There
is better documentation for a _different_ implementation with many of
the letters allocated to different functions here:

Have som ideas but to many other things, installed a door to keep noise from

It's often easier to hand write code for simpler jobs or use the machine 
in a mix of manual and MDI. It is well worth adding a couple of 
electronic handwheels. You end up with the hands on feel of a manual 
with the power of a CNC. Andy's macros look awesome. I must give them a try.


For more complex stuff CAM is the only practical solution. I do quite a 
bit of curvy decorative work and it would be a nightmare to hand code.
There aren't many decent lathe CAM packages out there that don't involve 
getting a mortgage. Fusion is pretty impressive though you need 
Windows/Mac to run it.

Best is learning how to write gcode, Ron.

LinuxCNC's gcode interpreter is far more capable than the average gcode 
emitter. It understands subroutines, if/then/else, while and 
repeat/until loops. I strapped a dremel handpiece to the head of my old 
micro hf mill, designed to sharpen my carbide tipped table saw blades. 
About 90 lines of code, took nearly 3 days to run.  Sharpest blade ever, 
and outlasted a new version of that same blade by about 10/1.  Had that 
file been unrolled by a cad/cam program it would have been many 
gigabytes of gcode.
