After Month of machining without any problems -Positionerror and no more moving

OK, looks, like the old MESA Card has an issue.
I reconnected the old one and same problem.
Now I installed the second one and everything works fine.

So it's a new experience that MESA cards can also break down sometimes. 

Thanks a lot to all.
Next project ist coming with upgrade to an ATC Spindle with a Cabinet.

best regards.

No they do not break, at least none of over 70 or 80 or more i have in daily use, they never break, never fail, in over 15 years.
Most of them are on huge industrial machines, some on plasma machines that are the worst environment regarding EMI, i have Mesa 7i92 wired through 6 meters of cable to plasma source with no BOB, directly to Mesa inputs, etc etc.
They always, always fail due to miss wiring or lack of proper shielding/grounding.

OK sounds nice.
I also didn`t think that this cards realy break.
So i will test this card on my new mill if it`s ready and hope it will work in a new envirement.

Thanks Tommy 

You are welcomed, always.
Be mindful of the wiring and shielding, since your machine was working fine, i doubt you have interfernce from VFD/spindle as they do produce a lot of EMI, so try to arrange spindle and high voltage wiring as far from low power/signal wiring, also use ferrite beads on the spindle motor wires near the VFD.
