I'm not sure what you mean PCW,

Your initial ping statistics had 3 and 4 usec times which are not
possible unless you are pinging the host.

Also the address range of enp3s0 overlaps enp2s0
 
This is why it's suggested to use the FPGA cards 10.10.10.10 address.
( as it will not overlap a local network DHCP range )
 

The N100DC draws no more than ~20 W...
Basically a laptop CPU in a Mini-ITX format

Perhaps Archive.org is your friend.

It would be easier with a starting hal/ini file set because
while the Mesa and LinuxCNC pin names are known,
the specific signal names used are configuration dependent.

(signal names are arbitrary and everyone uses different ones)

The problem with 12V is the wiring has to be quite thick due to the low voltage and high required amperage.

240W (average efficient PC) needs 20A at 12V.

With 20V, 240W only draws 12A, which requires less copper.

What power supply do you use?

I resigned.
Can you tell me what lines you would put in the fictitious .hal and .ini files to make the step-dir spindle work?
for lathe config XZ(C?)
Or a link to an example.

thanks

The led name will be the button name with '-led' on the end.
in the above example the pin name would be 'SCREENNAME.mybutton-led'

I checked my randomly-purchased liner scale (found at EMFCamp) and that is an LS 903 (no C) so is probably no help.

Late to the party, but I have recently switched both my machines to run from the Asrock N100DC-ITX board.
Latency is "fair" rather than good. But they are avaialble, run from 12V DC and can be booted from an M2 SSD for a neat installation in the machine cabinet.

(Unhelpfully, out of stock, maybe because I bought three of them from there.)
Apparently they are picky about memory, especially at 12V rather than 19V, so maybe buy memory at the same time.

You might want to set feed-hold when the needle is down, and release it when the needle is up...

I think that if you scale the potentiometer voltage to position, and latch it in HAL (you can do this with a mux component, with the output wired to the input, and triggered by machine-is-on) and add that to the scaled encoder position from the motor encoder, then you would have a "good enough" absolute encoder emulator.
Then configure HOME_ABSOLUTE_ENCODER in the INI

A month to go to the LinuxCNC developer meetup in Norway.

Original announcment:

As last year Petter and I would like to invite you all to small
LinuxCNCand free software fabricationworkshop/gathering
in Norway this summer for the weekend starting July 4th 2024.

We would again suggest to organize it as an unconference, <URL:
en.wikipedia.org/wiki/Unconference >,
where the participants create the program upon arrival.

The location is a metal workshop 15 minutes drive away from to the
Gardermoen airport (OSL), where there is a lot of space and a hotel only
5 minutes away by car. We plan to fire up the barbeque in the evenings.

Please let us know if you would like to join.  We track the list of
participants on <URL:  pad.efn.no/p/linuxcnc-2025-norway >.

The NUUG Foundation, <URL:  www.nuug
< www.nuugfoundation.no/ >foundation
< www.nuugfoundation.no/ >.no/ < www.nuugfoundation.no/ >>
has on our
request offered to handle any money involved with this gathering, in
other words holding any sponsor funds and paying any bills.

NUUG Foundation is a spinnoff from the NUUGmember organisation here in
Norway with long ties to the free softwareand open standards communities.

As usual we hope to find sponsorsto pay for food, lodgingand travel.

Previous instances have been informal, with discussion of LinuxCNC and tinkering with the machine tools in Petter's cathederal-like workshop (including a crypt). Norway is famously expensive but the hotel we use (Best Western Leto Arena) is surprisingly affordable at NOK790/€68/£57/$78 per night. 

One major issue of understanding/misunderstanding for me ist that when I try out example files for hal and xml i always get the error that lcec can`t be loaded. Perhaps this is lost/replaced/ereased in the version 2.94? How could I adress hal pins without lcec loaded?

It would be so nice if anybody could share a 2.94 compatible setup for the i-o modules and servos drives. I always stuck in error I can`t resolve by myself for now.
A reliable starting point would be genious.

I would realla appreciate any help or hints. 

Good evening again all.

Everything above has gone well, i greatly appreciate the advice. I'm now working through Tommys servo tuning guide, aswell as the one i found from PCW, same instructions for the most part. 

I just have one potentially really dumb question, do the servos need to be fitted to the mill for tuning? thats to say, in order to do any tuning at all? Its cold (New Zealand) and im playing with CNC parts in the lounge in front of the fire, but the servos dont really react how i would expect when reading the guides and it occurs to me that they probably need something to load up against in order to work properly? they arnt very happy turning with any P value above 5-10, but this value provides very little torque. the F error is responding to tweaks nicely at a low P value as expected, but i cant then turn up the power without it getting upset. 

While i always intended to fine tune the servos on the machine, i was hoping to continue working through it in the warmth . 

Cheers
