Juki Nozzle Adapter

[vonnieda]

Juki nozzles are cheap and plentiful, they come in many sizes, and have spring loaded tips. They look like a good general solution, but we need a nozzle adapter.

The shaft of the nozzle is 7mm and it has a slot for a detent. I suspect we can design a nozzle adapter that has 3-4 spring loaded ball bearings to hold the nozzle in and make it auto changeable.

In addition, when the spring loaded tip is about 3/4 depressed, the top of it's shaft extends above the top of the shaft of the nozzle. I think this can be used as a z-probe either by having it touch a metal contact or sensing it optically or with hall effect.

The nozzles can be found on Aliexpress, such as:
