You _do_ need specific firmware for the 7I80DB with 7I76+7I85 daughtercards
If you have this, any serial card is supported.

In case you do not have 7I80DB 7I76_7I85 firmware, here it is:

 
 

No, sorry i should've explain it better. Its just one belt.

The reason there are two loops; i only had a few closed loop belt size (length) options off the shelf from amazon, i needed to make sure the tensioner i was designing could make putting one of those belts on easier. So you'll see a one 'loop' goes around the interior most path and the opposite it true for the outer path.

Its one belt around three components, motor, driveshaft, tensioner. i attached a smaller slice, hopefully my rambles make sense. 

Ok if the card doesn't need any specific firmware, then it's fine, I already have the bit file for the other cards. Is there some specific settings i should add to the hal/ini files for it to work?

Good afternoon I'm using Venoen P12b industrial PC that has GPIO pins in it and the BIOS provides settings to configure the state of these GPIOs at boot time, but I need to control them dynamically from Linuxf for use with LinuxCNC instead of an I/O module i wanted to to know if that was possible or not. 

Attached HAL Files

SSH and samba are security risks, hence usually not included in major distros.
They should be installed only by whoever actually needs them, and some security info should be digested before venturing into it.

The X-axis servo motor and drive failed a few months ago and I haven't touched the machine ever since. I finally got back to fixing the machine, but I want to make some tweaks to the tool changer.

Everything works ok, but I need to add a timing delay when making a tool change. The motor starts turning immediately as soon as you make a tool change, thus not allowing the tool changer to fully unclamp. This causes the tool post to move back and forth until it is unclamped and then it will do the tool change as it's supposed to. I'm sure if i keep running it like this something is eventually going to break or wear .

How do I add a time delay so that the control waits for the tool changer to fully unclamp, and then rotate to the correct position, and re-clamp.

I will attach my HAL files, I don't think I set it up 100% either.

Do you want Linux Mint 19.3 with LinuxCNC 2.8.4 ISO?
It uses 4.19.nn kernel, if i recall correctly, and it works a bit better on my older laptops and PC's.
I can try to upload to google drive, if it fits.

i have used mode 2 on x and z. they are working.

ok thanks

Which combination of cards do you have?

Oops should have read the title.

That's a fairly odd combination, what hardware interfaces do you need?
There is no standard firmware for the combination, but it can be built easily
 

There's 7I76+7I85S firmware for a 7I80DB but not for the 7I76+7I85.
I can make this if you tell me which version of the 7I80DB you have (-16 or -25)

Note that Sserial cards don't need any card specific support in the firmware.
(as long as there is a sserial port, any sserial card is supported)

The 7I76 has 1 free sserial port and the 7I85 has 5 free sserial ports.

Just did that and it seems possible. Now the next question, which bit file should i use for this configuration (7i80-DB + 7i85 and 7i76 with the 7i87 connected to the 7i76)? thank u

I was running this computer over a year on 2.9.x with no problems.
Anything is worth a try, new Intel card on order. It should be here tomorrow.

Do double check this, but it should be possible to just wire the 7i87 to 7i76 using a cut off LAN cable, the Smart Serial connector, info on exact wiring is on the 7i76 manual.
