Z axis screw

Post date: Jun 14, 2013 2:46:50 AM

A little more progress on my Z axis- I got the end of my Z axis acme screw turned down and threaded to 7/16-20 to screw it into the Z axis carriage. It turns out that the central rod of the acme screw is less than 7/16, so the 20 TPI threads are kind of laid over the acme threads. It still works, though, and screws in nice and tight.

I still need to finish up the tube to connect it to the stepper (you know, so it can actually DO something), but any progress is welcome.

As a side note, a quick test of the pump indicates that it will at least pump water. I still haven't tested if it'll pump through the spindle, though.
