Don't feel too bad about it, Steffan.  Its likely there are similar

A direct copy/paste from that web page. ;o)  With the word "zsync"

It looks to have been https for a long time, and git blame seems to

In any case, it hints that Gene is the only person to have ever used zsync...

I ssh -Y into Bookworm all the time (-Y might just be a Mac thing)
The thing that doesn't work is OpenGL, so Axis doesn't work.
But that's been the case for as long as I can recall, not a Bookworm thing.

Gmoccapy seems to work, though the test I ran just now froze at the
point that I loaded a G-code program. I don;t know if that always
happens.

I have used it in that fashion (as a PLC rather than CNC control), on a 
headless server running Debian 12, I run:

linuxcnc (start the hal loader script with systemd at boot, including 
some Beckhoff ethercat I/O) A python hal to mqtt bridge connects the gui 
to hal

mosquitto to pull in data from remote sensors

influxdb to do the datalogging

Node-red provides the gui and the non-real-time logic. Here is where the 
fun begins. Sorry, I don't know much about coding java. Between 
point-and-click programming and asking llm for custom java functions it 
went together quite well.

All you need on the remote HMI display units is a web browser to display 
node-red gui.


On another system I did a similar setup except the server is a Beckhoff 
CX5020 and all the sensors are connected to Beckhoff ethercat remote 
I/O. The CX5020 was a bit special to get started with. If I remember 
right, it didn't seem to have enough RAM to complete the installer 
successfully, also I think it needed to run 32 bit. I just installed the 
OS on another pc then cloned that to the 8GB CF card and the CX5020 
booted that.

It really made my day when I discovered linuxcnc supports ethercat.

[Emc-developers] forced distroo change

[gene h. <ghe...@sh...>]

I've had so much trouble with bookworm on this machine that the debian 
list, instead of helping, has now routed my posts to /dev/null.
And recent changes to the default display server have removed my ability 
to do very much if anything that requires the x server to do.
That means I have to goto each machines own keyboard and monitor to run 
a gui for anything including updates. A year ago I could run linuxcnc 
via an ssh connection to any machine, but now I'm blocked by display 
errors.  This routing of my msgs to /dev/null will force me to use 
another distro, possibly xubuntu as the basic distro going fwd.


Klipper, for 3d printers, uses a different method to facilitate running 
and/or controlling my 3d printers by using nginx to broadcast AND 
control the printer, from anyplace on my local network simply by running 
firefox or any browser point at the address of that printer. PrusaSlicer 
usees lots of webkit stufff to do this for my 3d printers. And this 
works very well, allowing me to run and control a 3d printer exactly 
from this machine as from its own keyboard and mouse without running a 
browser. klipper does NOT support the tiny displays used on most 3d 
printers, but is designed from the gitgo to use a 1920x common hdmi 
monitor of most any size so I have monitors up to 27" on my rebuilt 3d 
printers. So my printers all are using a bananapi-m5 for a booster to 
both enable the web server, and at the same time, offload some of the 
stuff the controller card used to do. Coupling between the controller is 
via a single usb-2 or faster port, which the bpi-m5 has 4 usb 3 sockets.

So I'm asking: Can a similar web based interface be added to linuxcnc?

This would alleviate much of the wasted real estate that tkinters 
limited gfx wastes. And would enable my ability to login into and even 
control a running instance of linuxcnc to monitor progress of a working 
operation. As this exists today, the only editor I can use to write 
g-code from this comfy chair is nano. geany has a lot more features but 
cannot now be run remotely due to this copy/paste from a login to my 
6040 mill:

gene@sixty40:~/linuxcnc/nc_files$ geany cocking-piece.ngc
Unable to init server: Could not connect: Connection refused

Geany: cannot open display

gene@sixty40:~/linuxcnc/nc_files$

And this is not linuxcnc. Fixing linuxcnc to run as a web server would 
not fix this, so I'd much rather fix wayland to do this. Any known tricks?

Thanks a bunch.

Cheers, Gene Heskett, CET.

NML doesn't seem to be maintained, most platforms it was designed to
run on are obsolete, is missing tooling like a useable code generator
that generates serialization / deserialization code from some sort of
interface description (thereby guaranteeing consistency and correctness
of that code), is using an antiquated c++ style, and because of that it
is really painful to change anything. A bunch of kludges and ad-hoc
changes accumulated that also caused and still cause some real bugs.

IMO we should strive to get rid of those dependencies and the schism
between the C++ non-rt and the C-only realtime stuff entirely if
possible.

And, considering the error being discussed in that dec 2017 thread I

etc.  It obviously wasn't applicable to our usage. Remove it, and see if 
anything breaks.

Not exactly, though you may have indirectly answered the question,

My thinking is that posemath has nothing to do with NML, and would
more logically be in the "motion" or "tc" sections of the source
hierarchy.

I don't think that we really want to link to the NIST library, as I am
fairly sure we have diverged, and Pathpilot has diverged massively (it
was looking at this that led me to notice where it was)

What Andy is likely wondering about is that posemath
https://www.nist.gov/ctl/smart-connected-systems-division/networked-control-systems-group/pose-mathematics-path-planning
is a library on its own. It should be a separate Debian package and LinuxCNC should link against it.

It took me a while, and I eventually figured that posemath is "maintained" together with more of rcslib at
https://github.com/usnistgov/rcslib/tree/master/src/posemath and next to it is NML in
https://github.com/usnistgov/rcslib/tree/master/src/cms from what I see.

I would very much like the idea to redistribute rcslib (with a different name because of the revision control system, like gov-nist-rcslib or so)
with Debian and as a start just have the Debian packages libposemath(-dev) and libcms/nml(-dev) crafted as packages from it.

Best,
Steffen

There was at one time a separate hal manual, which I've not checked 
recently, but I believe the halscope was in that.
