We're having an intermittent fault with a QSV-1 where it will on occasions oscillate violently during a run and this usually results in 1 or both Z-rods being destroyed, along with the nozzle currently fitted.
This has been on and off for the last 2 years, but recently we've lost 12 Z-rods in a month.
We've swapped over the MEI cards, had the machine fully serviced and hgad the engineer out 3 times... each time it runs fine for about 2 weeks then the problem reappears. Quite often the gantry oscillation happens upon closing the doors, but now it's starting to happen mid run.
Any ideas?
