I am afraid that I can’t help with the actual question, other than to say that

whats the error message?
whats the output of ip route?

Previously the whole tool-table was sent periodically in an NML

That's not the case now, though. And I don't think that there is any
limit currently.
there still is a limit of 1000. Im currently refactoring the whole tool 
management, making it much simpler, and removing all limits.

Did you recently pull master?
You are using python 2.7 which isn’t supported in master anymore.
The updating documentation has steps required to change the configuration for 
python related things.

On my haas the encoder is geared 1:2, the index is only seen on every second 
rotation. No issues. It only takes longer for the engagement move.

[Emc-users] Python3

[Rene Hopf via Emc-users]

Hi,

few weeks ago master changed to python3.

This usually doesn't require any config changes, unless you use custom 
scripts or glade screens.


I added some hints to the documentation: 
https://github.com/LinuxCNC/linuxcnc/commit/e74e8f60968aad9e6872069655df1de7166286a5


If you had to do anything else, please let me know.

EMC2 v8 to EMC2 v9 would be a major release :-)

The changes between 2.7 and 2.8 were massive compared to this.

I think that there is some misunderstanding of the dangers here:
Python 3 is available on all platforms currently supported by
LinuxCNC and
at at least v3.5 on all platforms supported by Master.

Python 3 would be listed in the package dependencies, and
automatically
installed.

Python 2 is already gone.

.
LinuxCNC needs to adapt to this.

There is no danger of "bricking" a machine, LinuxCNC already works
with
Python 3 and several of the existing GUIs. (including Axis)

GTK2 support is already tenuous, there are some packages that we are
having
to backport ourselves via the LinuxCNC repositories (glade-gtk2,
python-gtksourceview, python-rsvg). That isn't a viable long-term
solution,
we need to only have dependencies that are actually packaged for the
target
OS.


I think there is no other choice than to follow their guide ASAP.

"Porting Python 2 Code to Python 3"

https://docs.python.org/3/howto/pyporting.html


I think there is some misunderstanding. python3 is not the issue, most 
python3 problems have been solved over a year ago.


buildbot even runs the tests with python3: 
http://buildbot.linuxcnc.org/buildbot/builders/1660.rip-buster-python3


users would not even notice the change, unless they have custom python code.

The issue is gtk. you cannot use gtk2 with python3. its just a unlucky 
coincidence that both things are happening at the same time.

 The thing that very few You tubers do when designing 3D printed
 machines is to not simply copy the design of metal parts but start
 the design from the ground up knowing they will be using plastic.
 Plastic has very different strength and stiffness to volume ratios.
 So if your part looks like the metal equivalent it is a good clue
 you are doing "eyeball engineering" and your experience with metal
 is influencing your design.
 
 If you need to print a reduction gear and need a really big ratio
 the Cycloidic reduction system really does work better especially if
 the rolling parts are sealed bearing units that are press-fit into
 the plastic.
 
 That said, I've printed parts in plastic to directly replace metal
 or even rubber and I just have to accept the very short lifetime and
 low strength. Plastic is a good material to verify ideas quickly.
 
 In any case, use a timing belt for the flex wall and it might last
 30 years.

There isn’t actually any documentation on the tooltable or toolchanging.

No, you need to request it. Line 89 is the request. You can use only the f4 
part of the stmbl, and convert the signal to sserial.
Or just use a stmbl.

It doesn’t work because it’s not ssi.
Its hdlc over Manchester over rs485.
I fully reverse engendered the protocol(including crc).
Stmbl has support for yaskawa encoders, there is some documentation in the code.

the spindle-at-speed pin is affected.

Re: [Emc-users] new linuxcnc today, wants to rerun update_ini again

[Rene Hopf via Emc-users]

thats related to multi spindle, the conversion script seems to be incomplete.
the message about joint-axis is confusing, it just converts the spindle names.
rename the pins to halui.spindle.0.whatever
if you depend on spindle-at-speed, dont update, as that is currently broken...

- live tooling on a lathe, although in that case the main spindle usually does 
a coordinated move.
- dual spindle lathe
- gang tooling routers
