Oh man! I will definitely follow this project, it will be interesting to see the changes! when you trouble shot the indramat did you try switching the motors with there respective "channels" to see if it was a motor or drive issue? I guess it doesnt really matter now that the cabinet is empty haha. I know a guy that might need an indramat drive lol

I have had a bit more time to work on the machine now that I have put my tractor back together and it is out of the way, I have mostly been messing around with the gear shifting program. It is the one RotarySMP used, I have found that the program had been forked for a MH600e which is more similar to the setup that I have so that is what I am using now. I have been able to get the programs simulator to try to shift the gearbox but i havent figured out how to add the cam position switches to the logic so it doesnt know where it is going it just moves the cams.

Replied to other topic with seemingly same content.

Mesa 7i76EU comes with firmware loaded and ready to run, just use the included PncConf or MesaCT wizards to make a configuration for your machine.

I have no power for the last 3 days so using the phone makes it dificult to quote stuff with this editor, but in short:
-i have PlasmaC in daily use in over 10 machines, users got used to occasional stops and are OK with it, luckily rareley happens, i think it is 2.8.4 version.
-i have probably over 20 machines using the old hal THC i cobbled together, in daily use, never fails
-i had 2 machines plus mine using QtPlasmaC, had to switch back to PlasmaC. This was a year or two back, so i will give this another try when i get a chance.
-you and Phill are doing a magnificent job of supporting and fixing this, instantly, utmost respect
-PlasmaC has 4 or 5 ways of disabling the THC, most are useless, except VAD, and void lock sometimes. Right now i can not think of any other valid use case. BTW default should be at 60-70%, not at 95%.
-what should i monitor for the issue where the torch keeps going down till float switch triggers during cut, happens often and ruins the nozzle. More often in QtPlasmaC but that might be just luck
-what should i monitor for the issue where the machine moves to a cut position and just stays there? This happens sometimes even when doing a manual cut where pressing F9 shows the machine running on screen but nothing moves. DRO does not change, machine state does. Again this happens a lot on QtPlasmaC, do not recall this happening on PlasmaC so might be a QT thing. I think these are two issues, one during cutting where the Z axis does not retract properly during normal cutting, and the other stated above where nothing happens.
-i think i have an old config for QtPlasmaC on a laptop for my machine, i can upload that if you think it might help.
-i absolutely have no issues with intelectual property, i do and will post everything i do personally, as can be seen from many posts here, i am strictly Open Source everything, and i did reject any job requiring me to sign an NDA
Ooops, not very short

Can you help me with mb2hal?
Here is my old setup for vfdmod file for Danfoss VLT FC-51
There was only a few commands cw, ccw, stop and frequency.

I use N100 miniPC with good success. Anyway.

Yes, you have a Realtek network adapter.
 

Please install the r8168-dkms driver
"sudo apt install r8168-dkms"
 

Honestly one of the most terryfying things I have ever done to a machine. Point of no return reached. (Even thought I labeled all the componentens and still have the drawings of the original setup, so I could technically put everything back)

Now I can start to layout the new components in the control cabinet (with cartboard cutouts)

 

 

Thank you so much.
I had been using N100 PC (or such Atom CPU )  for CNC machine, but this time, I installed LinuxCNC to Dell small PC ( 4 core i5 CPU ) just because of having smaller latency and more CPU power.

I have attached lspci - k output. 

if calculations are fitted in the servo thread time(which should be 250u as industrial standard) it should be nice to see or try something new ... for 7 phase generator is lcnc waiting many years and it is step to its adulthood

Michel told me to update his code but from my point of view If anybody on anyhardware will want to use it .. it will me close to imposible create a rt stuff for calculations ... I think it has to be splitted to rt and non rt part which will buffering each other for reaching as small as possible servo thread times

I am not expert in that at all...

Posting here with some pictures and any stylization is hell, trust me ...

it looks pretty ... reduction of any jitter in the rt system is more than welcome ... pll is very critical stuff for system and it is nice to see its major improvement 

Which driver for network card are you usig for testing it for now? jittering can be produce by generic drivers too i think

I saw it was merged in the master ... we will wait for scott to public new feed or version? 

I've ordered a MESA 7i76U, should get the machine up and running once configured.

I'm going to park this one.

github.com/linuxcnc-ethercat/linuxcnc-ethercat/pull/465

new PR with pictures, which I don't want to repost here, look at explanation on github, I'm available for questions. code has been tested, everything should be way better now, and possibly can even use not so good hardware and achieve decent ethercat no grinding.

Hi all,

I’m setting up a Mesa 7i76E (Ethernet) with a single 7i76 smart-serial I/O board on Debian 12 / LinuxCNC 2.9 and appear to be stuck due to missing FPGA firmware.

LinuxCNC installs and runs fine, PnCconf completes, and the board is reachable over Ethernet, but field outputs never work:HAL signals link to hm2_7i76e.0.7i76.0.output-00halcmd show pin | grep 7i76 returns nothingdmesg shows no smart-serial / 7i76 detectedEstop / stepgens work, but no field I/O activity/lib/firmware/mesa does not exist, and I can’t install linuxcnc-firmware-mesa because the machine is offline and buildbot appears to be down.

I’m looking for a known-good firmware file for this setup (likely 7i76e_7i76x1.bit), or a working mirror / source for Mesa firmware on LinuxCNC 2.9.

Any pointers appreciated — happy to provide logs if needed.

 Thanks!

Tim.

Hey guys!

Hopefully I'm not banging a beaten drum here. 

I am on the very cusp of finishing my build with the MESA 7i76eu, only to find, like other by the sounds of it, that the boards do not come flashed with firmware. Can someone please help me out? this was discovered when navigating to linuxcnc_2.9.3-amd64.hybrid\firmware to find nothing in the folder. 

Please let me know any further information required, and any assistance would be greatly appreciated!

Happy new years!

Tim.
