I looked into the AB Proset 200 package. From what I found it seems to be around $7000 minimum for the package new. that's way too much for these old machines, and I don't really need all the closed loop stuff. These machines aren't going to be used for high presicion stuff, or even high production. I think ebay can do better, if I can just figure out what I need. I really don't need the touch screen and such, but I found a couple on ebay for a few hundred bucks, so why not. I figure it will be easier if I just strip the machine and start from scratch. I have one machien running, so I will keep the guts from the other two for spare parts.
Most of the functions are controlled by position swtiches, actuated by adjustable stops on round bars. Nothing too complicated. There are only three heater bands, and three timers to control the injection, cooling and ejection strokes. One thing that I have no idea about it the hydraulics. I need to find some schematics for it to figure out what is there.
Any more info you guys have is greatly appreciated.
BTW, here is a link to a thread about just this sort of thing.
