No, I’ve had this problem a few times, the desk works perfectly then a Vu freeze, rebooting, it’s perfect again for a but freezes again after a few minutes, a ribbon clean usually does the job, after the clean, it worked for maybe twenty minutes before another freeze, this happened twice, but not on the last session.
What’s really needed is to take the ribbons completely off the spikes and a fresh part of the ribbon put back on so no oxidisation, there’s a special tool needed for this?
