[Emc-users] Autonomous machines

[Rafael Skodlar]

This seems to be a good platform designed for embedded systems:
https://www.nvidia.com/en-us/autonomous-machines/embedded-systems/jetson-nano/

Trouble is in the bus not being a popular standard supported by numerous 
manufacturers with interfaces for additional GPDIOs, drivers for stepper 
and other motors, etc. Single manufacturer is also a concern in the long 
run but who knows what the future holds. Price is acceptable for serious 
CNC application IMO.


We know Linux is running on it. Add RT kernel with LinuxCNC and you have 
a CNC platform. CNC is autonomous machine after all.

I would be happy too, except what most folks want me to do when they find 
out I have the machinery involves a class 3 FFL, $500 a year, so thats a 
bridge I only cross working on my own stuff.

In the meantime, I'm a hobbiest, making stuff just because I can.  And 
the medium can be Maple, Cherry, Mahogany, Walnut or Butternut or even 
OSB as easily as it might be alu, cold roll, brass or even A2.

OSB is fugly stuff though. Not to mention that glue is hell on tooling.  
Worse even than plywood.

But I saw an eagle pattern for over a houses front door that this 6040 is 
about big enough to make, so once its making chips, might be a project I 
might be able to sell a few of locally. Something that image-to-gcode 
might be able to both scale up to fit the machine, and do it at bragging 
resolution. I think that would be pretty neat in a couple hundred bucks 
worth of birdseye or curly/fiddleback maple, or some pretty ray-flaked 
quarter sawn white oak or ash thats been inside & stickered for 10+ 
years, well dried.

First one of course goes over my front door as advertising. :)

Same here, have a nice Linux system with 16-core xeon  64GB of ECC RAM and
Nvidia GPU for runing machine learning.   I'm working on motion path
planning
around moving obstacles,  Like how to move on a bussy sidewalk

 It runs headless, way off in a corner someplace.

I was a full time UNIX user before Linux was written then watched as Linux
started to displace UNIX.  I jumpped on Mac OS X early on because of
it' was built on a BSD base.

The last Windows I paid for was Windows 95.  After that I'd accept a dead
computer
with a still valid lincense key.There is now reason ever to BUY windows
as
so many valid copies are put in dumpsters

Re: [Emc-users] ConFusion 360 / Conversation code

[Chris Albertson]

It's kind of self-fulfilling.  You get 2.5 D jobs because you do 2.5 D
jobs.   If you could make the organic shape parts for a prosthetic hand you
would get jobs making the organic shape parts for a prosthetic hand.

My use of this is at best a hobby/business  I hope to pay for the tools I
use.  But what I noticed is that as I learn to do more things I actually
start doing more things.   That sounds almost silly but it is 100% true.

Thanks, that saved me some time.I had wondered if Fusion 360 would run
under Wine.   Some software does, some do not.   You have to just try and
see.  It's good to know that it does.

I'd still worry a little about the graphics driver interface that Wine
presents.  Fusion like all 3D software needs a good high-end GPU.

There is another way to run Fusion without Windows that works even better.
Run it on MacOS.  I have  27" iMac.

Re: [Emc-users] ConFusion 360

[Martin Dobbins]

Sure, the way Microsoft has "educated" the world, people are only buying 
(leasing) their "OS" (or more likely buying a machine with their OS installed) 
because it runs a particular application they need or want to use.  MS DOS was 
something that they bought from somebody else inexpensively (it started off 
being QDOS, that name given by the guy who wrote it because it was a quick and 
dirty operating system, they lost the "Q" so it was then a MS dirty operating 
system)  The "genius" was the gui and the point and click interface that ran on 
top of DOS that put computers in every home and business.  Ask most average 
joes about computers and they're going to say Microsoft, or maybe Apple.  It's 
only the people that have been stung by MS business practices, security, disk 
fragmentation, ineptitude, etc. that actually think "is there something else?"

I like the idea of running windows in a VM ( I run it dual boot now), but it's 
going to need some horsepower to run Fusion 360, more than it would running 
natively.  If someone was going to invest in the hardware to do that, might as 
well buy a MAC (I would suggest a Windows PC, but most of those come with a 
bunch of bloatware which can be a pain/impossible to get removed).  Maybe one 
day Fusion 360 will be browser based and therefore not choosy about OS?

Martin




From: Chris Albertson

My claim about Windows from the beginning in the 1990's was that no one
ever bought Windows because they wanted to run Windows.   They bought it
because they wanted to run MS Office or some game or some other software
that requires Windows. Or, I guess another reason is they bought it
because it came pre-installed on some hardware they wanted.  But very few
people ever wanted just MS Windows

When Windows was new it actually was a kind of "shim" that went between the
application and DOS to provide a window and mouse interface.   Over time
they made it into an actual OS but still to this day its real use is just
way to run a certain class of graphical software.

Linux is a little different in that Linux is just the OS.The graphical
stuff you see is something added on and there are a half dozen popular
windowing systems in use over top of Linux (Android being #1) Apple's
Mac OS is kind of that way too.  It is a big layer over top of UNIX.If
would be good for Microsoft to split up Windows and make it a layer over a
base OS so we can choose each independently.   It might happen, don't know.

Today except for home users, itis very common to run virtualized instances
of Windows.   The virtual images an exist on a server and run on desktop
hardware and in this way the end user's Windows instance follows him to any
random desktop hs sits at.   Home users tend to use systems whwere the
hardware is tried more firmly to the software with software being install
on the local hard drive.   But virtualization is widely used in the
industry both for servers and desktops.

But runf this on top is UNIX is not so common are runing on top of a "bare
metal" viruralmachine,  these can be much lighter weight.   Microsoft's
"Azure" cloud service provides millions of vertual machines and they say at
least half of them run Linux.  Even Microsoft is now agnostic about OSes
and runs them in virtual hardware.

Re: [Emc-users] ConFusion 360 / Conversation code

[Marshland Engineering]

A very interesting discussion. I have delved into Fusion 360 plus a number of
other packages but I still revert back to Turbocad as it is quick and does
what I want. All the work I get is 2.5D. If I was making assemblies, then 3D
would be great but I make parts for companies and I normally just use the PDF
and program my machine with conversational programming. Sometimes, I get a
DXFs. Just done a $3000 order with no CAD or CAM package. The longest program
I needed in my machine was 9 lines long. Probably took 5 minutes to hand
program and test. (Forgot to take a photo of the finished parts.) As mentioned
before, GCode runs every line and ends up being a lot of code. In the
conversation mode, I use subroutines. I can drill 100 holes with 2 lines of
code. If I want to change the feed rate, I only have to change one line.

There are some very good engineers on this forum and I was wondering if any
see any merit in making a system that runs conversation mode almost
exclusively. Sure it will be able to run GCode, but conversational will be its
main focus. 

As I have said before, to train someone to use conversation is really easy.
This project is not for all types of work but I make a living out of making
simple parts.

If you are interested, email me off line and I'll take it from there. 

Cheers Wallace.

Which makes windows a little less distastefull. But Bill Gates is going 
to have to personally apologize to me for his phone people calling me a 
pirate for wanting a copy of ntfs 3.51's main library, which their own 
damned housekeeping deleted from an otherwise secured hard drive in a 
locked at night closet. That put our comm channel to CBS out of business 
and cost us a few thou before it was cleaned up.  I wound taking the 
drive out, packing it up in a static bag and half a pound of ghost 
turds, and overnight fedexing it to CBS, who checked the drive, found it 
healthy, and re-imaged it from one of their machines and fedexed it back 
to me. To this day, and I've heard a couple similar stories, I think 
ntfs 3.51 ($499 at the time) had a random timer set to run 2 or 3 years, 
then kill the os so you had to buy a new copy.

But I will not forgive M$ for calling me a pirate when I tried to argue 
for just that file to be sent out on a floppy so I could fix it.  Screw 
M$ and the camel that rode in on them.

So now you know the rest of the story behind my outsized hatred of things 
M$.  And this happened before I ever made my first linux install in '98 
on a 400Mhz AMD K6 cpu.  Fastest machine in the building then.  That was 
a breath of fresh spring air compared to what I seeing our sales people 
putting up with trying to do business with 3.1 or the new w95 of the 
day. Even then they were virus magnets.

Oh WOW!  Thanks, Alan!  I was thinking of making this as an 
accessory to the CRAMPS boards I make, but never got around 
to it. I had no idea somebody has DONE it!


Thanks,

Well, it may not be the best thing to run the VERY latest 
version. I found FreeCAD to work pretty well, but the CAM 
side would hang up and do odd things.  I was probably using 
too fresh of a major update version.

Still leaves it with the small pin headers using tiny wires that don't fit well 
with the larger screw terminals on drivers for larger motors. Made for screw 
terminals on the adapter, pluggable screw terminals could be installed so 
they're polarized, making a service replacement less "fool prone". Ie, unplug 
everything, install replacement unit, plug in everything - can't plug a motor 
driver control connection in backwards. Not without removing the adapter and 
plugging that in backwards.

Shouldn't need any additional components other than the small PCB, header pins 
and the screw block because all it's doing is changing the inputs to the Pololu 
from a pin to a screw clamp.

Having 16 pins plugged in with screw terminals on top would be quite a bit more 
secure than having four small pins as the mechanical connection to the external 
driver.

Instead of the step/dir/common pins going to a Polulu board, the are shipped 
over to the output connector on the CRAMPS board. So you can use the pin header 
to run on off board drive. If you are interested I can send you the schematic 
for the board. If the link above doesn’t work, here is the URL

Exactly the same current state of affairs as my reply to Gene's post ;)
I've been with SUSE since 6.0 days ... just finally thrown the disks 
out! Tried a couple of other distro's over the years, but for the 
servers it's the most stable and just runs mainly because there is no 
graphic desktop ... so keeping everything in sync makes sense, but the 
stable version of SUSE Leap15.0 is a little long in the tooth and while 
I have had 'Tumbleweed' running which is the latest and greatest version 
of everything it is most definitely not stable all of the time ...


 ... 0.18 is available on Leap15.0 ... magic ...

My main desktop machine has a nice 8core AMD chip and 32Gb of memory and

simply less backwards than KDE and having run a multi screen setup for 
many years it's now a fight every time they 'improve' things to keep it 
working. Even the ability to toggle between two desktops that straddles 
all for screens has gone, and I have to run a script to get the monitors 
back to the right order after a reboot. Progress these days is a hole in 
the shirt pocket :(

Don't you have a good Linux PC with at least an i7 processor?  3D CAD, even
if you could get it to build on low-end hardware would be horrible to use.
  You want at least the i5, 4GB RAM and a 20" screen with a good GPU card.
  But even that would lag badly.  A newer quad core i7 is a better
processor.   You want the image to re-render nearly instantly, faster than
human reflexes can detect. Otherwise, you don't get smooth rotations.
To be usable the 3D model on the screen has to move as well as if you were
holding a physical model in your hand.  If the screen image lags detectably
it is unnatural to use.

CAD is one of the use cases that justify "workstation" class computers.
The other might be video editing and sound mixing or high-end video games.

Hmmm ... just found: https://github.com/lachlanA/eagle-to-kicad

When there's time, I'll have to try that on one of my boards.
The size limitation on the free Eagle can be a bit of a nuisance,
though two layers do me so far.

Re: [Emc-users] Wish me luck. I am downloading v.18 of freecad as src, gonna see if I can build a 32 bit version

[Bruce Layne]

I decided to install FreeCAD 0.18 to get the latest and greatest
FreeCAM.  Thanks for the encouragement, Lester.

I'm running Ubuntu so I didn't need to compile anything.  There's a
FreeCAD daily repository for Ubuntu.  Details are here:

https://launchpad.net/~freecad-maintainers/+archive/ubuntu/freecad-daily

When I searched for the above link, I also saw a link to a YouTube video
demonstrating the FreeCAD daily installation process if you like, but I
didn't watch it.

All I did was:

sudo add-apt-repository ppa:freecad-maintainers/freecad-daily
sudo apt-get update

Then I ran the Ubuntu software updater.  Holy cow.  The FreeCAD
documentation is a third of a GB.

Then I did:

sudo apt-get install freecad-daily

Ta da!  Version 0.18.

I removed the ppa from the repository because I'm not a developer and I
don't need (or want) daily builds.  I just wanted the latest FreeCAD.

sudo add-apt-repository ppa:freecad-maintainers/freecad-daily -r

The above should work as well for a fresh install rather than an
upgrade.  In fact, I left the stable FreeCAD 0.16 installed in case I
have problems with 0.18, but 0.18 seemed able to open the parts I
designed with 0.16.

Sorry if you aren't running Ubuntu and have a harder time getting the
latest FreeCAD, but the above *might* work for other Debian based distros.
