MAke sure you have the Realtek R8168-dkms or R8125-dkms driver installed for your realtek card. It may fix it.

Dear Colleges I what to share my experience on this topic.

I after several years looking for this card, I get a mesa card,
looks a Clone one, V2. (kind of clone of 7i92) Pls. have a look on picture attached, I get his one because was easy way to get it, at the beginning  I try to purchase the original one but was not available to be send to my county and after, after they were lack on cards, and after they start to shipping to my country but  the shipping cost became  more difficult to get  that original  card, and after I was looking on amazon o other retail pages and then I found this one on aliexpress. I was thinking it was the original but after some research I understood that it  was a clone one of original one. but cheap and easy to get (shipping cost included) and for test propose I run the risk to get it

well now I use it with my PC box and I do not load any other bin file. ( I see on forum load a bin file is not a good Idea).

Supplier support = after the time they send me the card information
Process to make it talk and work with linuxcnc (debian 12). 
1.       Configure the ip on my dual Ethernet port pc box , card ip 10.10.10.10 my pc 10.10.10.11 port 2 and ethercat on port 1.
2.       Install the mesa card utilities
3.       Install the ethernet utilities
4.        I discover the card io setup by maker
5.        I use linuxcnc wizard (PnCConf) with discover option 
6.       end configuration and start running the Linuxcnc
7.        communication with card disconnect issues , solved by disabling the power save option on the realteck Ethernet com card and after not more issue by the moment
8.       If I do not have any other problem I will replace my old and good  PCIe parallel port card that make  my fadal cnc  run G0 at 200 IPM. 
fadal can run up to 600 IPM but this is not my goal to stress my cnc at that speed. ( perhaps I will test it with this new card)

 About Ethercat  servos and I/os card I been testing,  I have  a hybrid configuration with ethercat, and parallel port and this configuration is working but realteck nic is having disconnect issues that the community say the intel nic is the good one for ethercat and servos, and test it with IO ethercat cards and this realteck nic do not notice me any issue, 

 I do not have a pc with intel NIC yet.

Please share your comments and experience.




 

 
 

Yes. you need a separate supply.

You can often use a 12V supply and scale the PWM so that full RPM = 10V
 

Hello,

I've been using the 7i96s potentiometer function to control a DC driver board on my mill, 

I'm replacing that motor with a Chinese servo that requires a 0-10v signal to be driven in speed mode, 

The drive itself does not have a +10v that I can feed the digital pot on the Mesa card 

Would I require a separate 10v power supply to feed the Mesa card digital pot to output the proper signal for the servo drive?

Attached are the wiring diagrams form the servo drive, and the link to the servo kit:

Thanks for your help!

I don't know why this conversation got down to swap drives and building LinuxCNC from source. None of that is necessar. LinuxCNC only requires 4-8 gb RAM but I think I'd lean towards 8 gb today.
 

The author of topic asked for the latest version of LinuxCNC.
The latest version of LinuxCNC is compiled from latest sources...
Compilation of LinuxCNC is easy, easier than many things you have to do after.
Where see you problem?  

I agree, many things are not neccessary, for example PC computer is not neccessary, and LinuxCNC is not neccessary, you could use GRBL  controolled from smartphone, but this is not the subject of the topic.

Modern Linux needs 2 (two) gigabytes of RAM.
Some programs needs more, but LinuxCNC not belongs to them.
My computer I use to write this post (Ryzen 5 with 16 GB of RAM running Firefox on Debian 13.6 with xfce4) uses now 2 GB of RAM, and believe me, this may be less if less memory is installed.

I see, we are on different levels of using Linux...
For me copying whole partition to other disk is normal and often used procedure. I don't need unwanted dependiences, like system not starts without swap partion leaved on old disk. I not need any swap partition, because Linux can use for swap file placed on any mounted partition, and you can turn on/off swap when you need (swapon/swapoff).
Swap file is correct solution, swap partition is a prayer for troubles...

You may use defaults installation settings, and it should works, but why you deny talk about how do it better?


 

' IF I unplug all of the ports on my lathe board and move it over to my mill, the mill does work and linuxcnc connects'

I assume you are using the same known working Ethernet cable in all cases so you can rule that out. Assuming you have the problematic 7i96s on your bench with only it's ethernet and good 5v power connected, I would probably cycle the power and the IP related jumpers (W4 and W5?) and see if you can get it to ping on any address. Beyond this, you can try using mesaflash with the card type and AUTO to try and scan to locate the card. I've had the EEPROM corrupt on my card once and needed to reflash with 'mesaflash --device 7I96s --write <path_to_firmware>.bit' to get communication working again.

I have been tinkering withit and managed to get the touch probe to work, 
what I think its happening is that QTplasmaC doesent want to run any Gcode or any of the user buttons, because the borders of the windows just turn white I click a button or hit cycle start

is it possible for the machine to jog correctly but not run Gcode?
what could be causing this?

I am using a single ethernet port on my computer where only one board is attached at any one given time (so I unplug one board and replug the second board)

Are you using seperate NIC's for each Mesa board?

I am really struggling to figure out what the issue is here and am looking for some help. Prior to moving states, I set up linuxcnc with my mill and it was working fine, I then purchased a lathe and another mesa board (both are 7i96s) and attempted to set it up and I was unable to do so, it took a lot of debugging with AI but eventually I found a way for both boards to work even though both were set at 10.10.10.10. However, now after moving, I have set everything back up, and my mill board does not communicate with my computer at all and I don't remember how to solve the issue. Here is what I know so far:

1. Originally, both boards were using EEPROM jumpers and 10.10.10.10 (and my HAL files reflect those IP addresses)
2. The default IP address has never worked for me for either board
3. Currently, my lathe board works correctly, when I plug it into my computer everything connects up right away and works as expected, it is also the last board I used prior to the move (meaning my lathe was the last machine I was using)
4. I am unable to ping the mill board, mesa flash does not recognize any 7i96s connected when the mill is plugged in, because of this, I cant change the IP address
5. the LED lights / sequences are identical in both boards on powering up
6. I tried upgrading linuxcnc and updating my packages and that did not help
7. IF I unplug all of the ports on my lathe board and move it over to my mill, the mill does work and linuxcnc connects


It feels like there is an IP address conflict or something else going on where it's expecting the lathe board because that's what was last used. I recall having this exact same issue when I first purchased the lathe but for the life of me I cant remember how I actually fixed it. I do not think the actual mesa board is broken in any way.

Does anyone have any big picture suggestions on what I can do for further debugging in terminal?

Yes, can Post it this afternoon. But Keeper ik mind it currently is configured for my bench test setup, and homes without homing Switches.

Hey, could anyone with a “2 motors on one axis” setup send his config in this tread, im a little stuck configuring my setup
