Boxes have started to come in, this batch from robotdigg.

Two Nema8 stepper motors. One with a hollow shaft and nipple for the C axis and a somewhat longer solid shaft one for the Z-axis. I'm thinking a Nema-8 with a screw drive should have ample torque for Z, no need to load the X carriage up with another nema-17. These came with wires.

3 juki nozzles size 503, 504, 505. I really like the spring action on these. I should be able to measure them accurately for machining the holder concept.

12 vacuum pump.

two 4V110-6 2 way 5 port solenoids - which, after dismantling them and figuring out how they work, I understand are completely useless for this project. Which is annoying because they were not cheap.

I have, however, ordered a 10 pack for $10 of these from American Science and Surplus: http://a.co/d/5EGJJMB
