Recently i came across an amazing deal on a Stratasys SST printer. The problem is i have never had or used a 3d printer before and my coding experience is limited but still generally above par (or so id like to believe). I have about 2 years experience the Google Youtube 3D Printing University so my approximate knowledge of the situation is vast but unhelpful.

Problem is, they took out some of the juju that runs it. So i improvised and ordered a rambo 1.2a from amazon.

The stepper motors are 8 lead steppers with your standard 4 wires coming up for the top and the bottom coils. Even through i am able to put alot more juice in these steppers they wont be much of an upgrade from nema 17s with my setup. (if even possible)

Which leads me to my first problem my steppers dont move or even tighten when connected to the board. Which makes me beleive my 12 volt power supply is the problem (i dont have the confidence to hook up the powersupplys left in the machine)

The rambo board has repetir firmware and connected to repetir host on the computer on it (i somehow bricked it and figured outish how to re program it real fast). The next thing i want to connect is the heated chamber and lights and fans.

Theres 4 fans total with revered plastic blower thinggies and polarity protection to make sure the air goes through properly. And 2 heated thinga ma nigs on each side of the chamber. I have a budget of about $500-800ish more dollars to make this thing put out some low quality dental floss and was thinking of wiring all the fans/heated chamber separately. So any help in pointing me in the right direction to make this thing print at least air would be greatly appreciated. There is still a lot more going on in this printer that i haven't gotten to yet. (possibly provide some inspiration for your own diy project).


All the options and do hickeys in this thing to fine tune prints are are nice and all but my first goal is to at least make the stepper motors twitch.

Some pictures my friend took of the steppers, chamber fans and max end stop for those curious.
