Hello,

I've been retrofitting an old lathe with LInuxCNC. An old 9-step
electromagnetic gearbox was replaced with Toshiba VFS-11, old asyncronous
servo motors got replaced with a couple of newer servos in position mode.
Thus I use 5i25+7i76 on D525MW. First I successfully set up the VFD for
manual 3 step gearbox, then I connected Z axis servo drive and it was
jogging around pretty well.

The next day I powered up the PC and Z servo drive (but not VFD), the PC
started booting. I remember the boot log appearing and then suddenly the
screen gets black. Since then no picture from that PC, even no bios logo. I
checked the display, the PSU etc with no success.
It looks like the D525MW is dead. Pretty frustrating.

Here's the first question: could it burn because of some electromagnetic
issues? I used 12V from PC for 7i76 field power (is it wrong?). The
(chinese) servo drive was connected to STEP/DIR in differential mode. The
servo drive is supplied directly from 220V, but it has opto-isolated enable
input, I connected it to GND and one of the field outputs.

Later I took another D525MW which had been used with 7i43 + 7i48. But
somehow this D525MW doesn't see the 5i25 board. I get "... hm2_pci.ko: No
such device" error. lspci doesn't list 5i25. But the 5i25 lists on another
PC and the config starts OK.

The second question: what can be wrong with this D525MW?

Thanks!
