I picked this up the other day after winning it on ebay for £10.50
It is some kind of manually operated, negative scanning machine for digitizing photographic negatives.
This is my knid of swag. It's loaded with goodies and ideal for CNC conversion.
It's pretty much ready to go, as is. The linear motion hardware is nice and tight, but slides freely. All axis are chain and sprocket drive. I thought I'd have to replace these with belts, but they seem to have very little backlash. I've not measured it, but it feels like there's no slop at all. So I'll see how they work, before stripping them out for belts. I've stripped most of the stuff off that won't be required. This is much sturdier than my homemade CNC router will ever be. It even has a ballscrew to raise/lower the entire table and gantry, so you can have it at just the right working height. How thoughtfull.
So the plan is..... To get some shafts poking out from the chain drive mech on all 3 axis, so that I can attach the steppers via HTD belts and pulleys and make some kind of table to replace the glass & lights.
I have some steppers that should do the job already. I'm planning to put the PICStep drivers I built, in a purpose made box, so I can move the box between machines and just plug the motors in. (untill I build another set of PICSteps).
So not too much work really. Some head scratching to do over how to get the shafts sticking out far enough to attach a pulley. I have some ideas tho'.
I'll post pics/updates as I progress.
