Mark,
I appreciate your words of caution. Sometimes, though, when one doesn't have the financial wherewithal, the only option is to use one's brains, mechanical skills, and time!
I should be all right with the purchase - already made, BTW, a z3200PS 44" model - if the only problem is the lift assembly code indicated. I do have the service manual at the printers, and have noted that there are a lot of videos for this machine. I don't know if that's good or bad
but figured it'd better to pick up something that's been around a few years and accumulated info on the various problems that can crop up (...or hit you in the middle of an urgent job: in your own immortal words: "like light bulbs going out"!)
I didn't mean to imply with my comment on the MECH board that I myself would be doing an upgrade from plain vanilla to a PS model... just curious what the procedure is and if there exist any workarounds.
My first challenge with the machine will be to move it: all 130 kg/2 m from Houston, Texas down into southern Mexico! Wish me luck!
