the ISO on the downloads page includes 2.9.4. Trixie/SID is a work in progress. Its not trivial to comply with the Debian build environment and a whole host of  QA requirements imposed by SID. The devs do try...

vi is very old-school. Nano is somewhat easier. I use it with SSH to edit files on another pc. The Linuxcnc includes geany  which is a GUI based text editor

I can't see why the new planner can't be put in its own folder under /src/emc together with its build system. Surely linuxcnc's make system can call another build environment. In fact some of the lcnc code is written in c++   

Have a look at the header files in src/emc/rs274ngc. Classs don't exist in C  

hakan is on the right track
There are a couple of xml files here with configs for Rtelligent and Deiwu I.O modules created exactly how endian menrions

 If you get a USB wifi dongle with an external antenna you can get a SMA extension cable with a bulkhead connector on the end. Drill hole through enclosure, insert fitting and attach with supplied nut, and attach the antenna from the dongle. I have done this a few times now.

small update moving forward with this.

Found another problem that seems to have fixed it. The machine is manufactured in the east, the input switches/buttons go through a wide metal clamp that I assumed was frame grounding the shielding of the wire, it was not. When I earth grounded the shield with the setp suggestion the random EStop trip seems to have stopped. It will take more tests to be sure.

Input common is Negative on the 24v PS. Limit switches are inductive and signal 24v when tripped, EStop will be 24V normal, 0V when triggered.

Yes, limits triggering will also cause a fault and change to machine-off state.
Maybe a wiring issue with the input common, or just limits/estop wired
near power signals.
 

ok there is a freight train at the end of the tunnel!
It worked sort of. Not stable but it did show what is happening.
I put the setp on all inputs.
The EStop I now see toggles which it should not. The EStop is not actually wired yet and will be normally closed so there is always a 24V. Would this stop noise? The limits send 24V when detected but the spindle is not running. Will a limit triggering while operating cause any issue?

No need for a base thread with an external motion controller.
I run mine with a NVMe drive, yeah boot is really fast, I've been playing a around with custom hardware and hostmot2 firmware over SPI. ATM I'm working on a ethernet board to replace the SPI\EPP board that mates with the fpga board I'm using.

If you could add your Etherent mods to the thread linked below it would be great, trying to have a one stop place for all issues/suggestions and such.

I think the raspberry pie five and Mesa set up is really quite brilliant. It’s very compact, and boots up really fast. The only negative i have found is that it’s difficult to put an external Wi-Fi antenna on the pie. If the pie is inside a metal box, it won’t connect easily to a Wi-Fi router. You can get around this by using an external Wi-Fi dongle. Or move the excess point and pie closer together.

The reason I was running that test was because packets were being lost between the raspberry pie and the Mesa board. I couldn’t figure out why. It was suggested to change a setting (I forget which one, but it is documented on The Forum) and after that there was zero packet loss.

Yes. I don't always trust over seas items so even if they don't have a ground lug they are grounded. All wire has grounded drains, 7i96s frame ground, emi filter, spindle, machine frame, stepper drivers are all grounded to earth ground

Looking at the hal file, I would suspect the estop input so you might try adding:

setp hm2_7i96s.0.inm.00.input-06-slow true

(the noise may also affect the other inputs so you might try with all)
 

Does the machine and PC have proper grounding?
