They should be in the initial post, let me know if they are not please.

sorry my mistake i will post correct question below.

with this 7i76 i need 4 axis (for 4 motors) and i want to use the (what is normally the 5th axis) for a PWMGEN. Which if any firmware do i need to flash ?

this is to send pwm to a dac for one of my equipment features as i am already using the spindle output

@Aciera thank you very much. It worked flawlessly. I knew I can count on you guys

I wasn't thinking of putting it the connector shell but having a surface mount connector if they exist that plugs straight in like a raspberry pi hat.
The amphenol connector used by Hypertherm and Thermal Dynamics, I think comes with surface mount options....

Glad you like my idea, Pretty cool one I thought!

Ceres template for our codebase

Ceres example

7i76 has 5 step/dir outputs that you can use any way you need/like (it can do 5 more so total of 10 with an added BOB or 7i75 or another 7i76).
Is that for a tandem axis ( 1 axis with 2 motors and 2 drives) ?
The wizard can deal with that also, just choose a tandem X axis or tandem Y axis or whatever you need.

Thank you gentleman i disabled the secure boot also enabled legacy support not sure which it was but its working now.

One more question

with this 7i76 i need 4 axis and i want to use the (5th axis or what is normally) for a second stepgen. Which if any firmware do i need to flash ?

Looks fixed to me.

Wish the LinuxCNC X86 image had the RealTek DKMS driver pre-installed
as the stock driver is NG
 

-Disable secure boot in BIOS
-do not choose parallel port in the wizard
-might not need firmware at all, depends on use case and what is already in the card, check using mesaflash
-ignore the wizard complaining about Mesa firmware, only needed for older Mesa cards

Looks like a LinuxCNC build issue:

iopl() failed: Operation not permitted

cannot gain I/O privileges - forgot 'sudo make setuid' or using secure boot? -parallel port access is not allowed

 Also Mesaflash will fail if you use --device 6i25 since the 6I25 card has 5I25 firmware installed.

hello,

im sure this has been covered, i just cant seem to find specifically what i need.

I have an HP ProDesk 600 G1 SFF Desktop with no physical parallel port and a brand new from mesa 6i25 card.
computer has no pci sockets and 2 pci-e sockets
Installed is current stable release of debian 12 with linuxcnc 2.9. (The one and done install)

1st - install 6i25 (in both slots) and run lspci it is there.  (02:00.0 DPIO module: Device 2718:5125 (rev 01))
2nd - Tried to add firmware for 6i25 and it says  no card present or something to that effect
3rd - created a cnc setup with pncconfig wizard. Message (pasted below) i gather (-parallel port access is not allowed)
              Is the root of the problem.
4th - could not find anything in bios that jumped out at me. Pci-e auto detect is on and Pci-e power conserve is turned off
             those are the only 2 references to pci-e ports in bios
5th - checked hp website and it said no parallel port or driver installed. I know there is no driver for the 6i25.  Is there a                                  driver needed in debian for the pc ?

please share your thoughts and suggestions on how to proceed ???

Thank you
kent

tommylight, thank you for this tip! Yes indeed, I had the line sudo ethtool -C eno1 rx-usecs 0   on my Desktop to put it in the terminal each time after the PC starts. That helped a lot for the ping as I used the Intel NIC. So I gave Chatgpt the job to make a one-click file out of it, successfully. I can post it here asap, if I go down to my Linuxcnc PC tomorrow (Germany time)THe Realtec NIC is configured by start with coalescence=0, afaik.

PS: Below the file with double click function. delete the .txt and make it executable as a program. (ethool was the name Chatgpt gave it  )

 

this fixed the issue thank you!!

BTW - I tried a lot to get the Intel going, but it was very frustrating and not successful, months ago, you gave me a lot of tips.

Intel might need coalescing set to 0, PCW knows how, i never needed it despite using all kinds of PC's, but there are plenty of members here who needed it and it works properly.
