Great, let's share our experience. Here's more info on my situation:
It's stopping in the middle of the job and displaying Y POSITION ALARM, flashing led and requiring a reboot. My tech informed me that since it's stopping at the times I mentioned, like during the contour-cut and at the beginning during intialization. It's still working well and this doesn't happen often, just enough to rattle me for now. I've had to just about toss a few things, but I've been able to salvage them so far. Here's the dilemma
This setup with my older software and equipment is obsolete and I'm considering now what happens when I have to purchase a new machine. Basically, it means bringing everything up to date, printer included. This plotter was obsolete in 2008 or so. It was produced for 20 years or so I believe the tech told me. I jumped in during it's mid point and now regret parts are no longer available. Kinda strange that. It's like they just want to sell the new machines, make it more likely one would, at least.
