Mesa 5i25 PCI Issue sporadically need #Help#

Hi Guys,

i am new in this Group.

I hope u can help me out. i converted a Manual Mill to CNC and run it quite a while no faults or problems until last week.
Standard 5i25 /7i76 Config.
When i started Linux CNC it shows me " no mesa found.." so i typed in mesa flash and it shows me that theres a card in but no config.

-> empty FPGA ?!
After that i unplugged plugged back -> started EMC -> worked until yesterday.

Yesterday was the same and i repeated everything and worked good, i run a cycle and in the middle of it serial errors and stuff popped up and no communication was given, after that the machine stopped. There are no lights on the 5i25 and the Cable is good.


Is it more a PC Problem or a Card Issue?!?

Thx for help!!!

Got a spare power supply? some of the mesa cards are sensitive to low power.
i had a system that ran put the card didn't work properly. on suggestion I changed the power supply and that was the issue.
If you have a spare - easy check.

Thx, that could be possibly.

for field power i got a industrial 24v power supply.

do u mean the computer spare power supply??

regards

Computer.
Field power can influence missing pins on launch (field power is required for the pins to be made).

ok - yes this is an old dell i guess it has a spare power supply .. what is better ?.. what to look for ?

maybe i upgrade the pc to a NUC or something...

regards chris

I would just temporarily swap out the power supply if you have one handy just to see if that helps.
It could be many other things.
