After getting lost in the mail for 3 weeks, I received my ordered digital stepper controller KL4042, having some Nema 23 stepper laying around, I did got, that idea, for an digital compressor driven by a stepper for paste deposition.

It's part of my other project, the one for the contest, it's also the reason why I'm so late to present it.

While mounting the first 3 controller I did preview to get a forth axis. Now I just have to screw it in, and connect the cables.
