Mesa 7I92 and 7i96 not on supported mesa cards list. Voyage of discovery?

Dear Forum,

I am about to buy a Mesa 7i92 or 7i96 the next days. Searching the documentation on linuxcnc.org I didn't find any of those cars on the list of supported cards. I know that others are running these cars but what does that mean to me in terms of setup and configuration?

Best,

Markus

Have you seen this forum.linuxcnc.org/27-driver-boards/3504...6-configuration-tool

Thanks for the great link. I haven't seen it. Obviously the forum is faster than the documentation

You helped me a lot guys! Thanks!

what mashine is it as you are on 2 cards to decide
the 7i92 needs some dauter card no matter what DB25
and the 7i96 is ready to use for a standard mashine setup

It is a 3 axis machine (gantry type). It has been running on a Chinese 5 axis BOB until the PC died (still unsure why).

Currently it denies working on a new BOB (same model) due to maybe cabling errors and not enough voltage for all 4 drivers at others because the parallel port or the too high USB power consumption causes the PC to boot only when all cables are disconnected (or randomly? Didn't dive into that). So basically I am fead up with the LPT driven stuff. I lost months fiddling around with stuff that stops working after a couple of ours.

P.S.: I can catch myself thinking of going back to GRBL and arduino uno

I have seen something like this issue (no PC reset) when you accidentally
backfeed the PCs 5V or 12V supplies with external power.

That is exactly what I am fearing. But currently it is powered by the USB, 12V is not yet connected. The 5 V supply is as well not connected. When I received the PC LPT was deactivated in the BIOS and it does only boot successfully if the LPT is set to automatic (even if no cable is connected). Hence, the PC might have an issue with the LPT as well.Not much luck with this LPT stuff!

That is why am going for a MESA. Ordered a 7i96 today.I hope that makes things much easier.

@tommylight: you have been right. Yesterday the second PC died. Both PCs cannot mount the hardrive anymore and are basically plain dead. They only can run a live CD anymore. No idea what caused the damage since they died on a different electronics box, so one faulty BoB can not be the reason
