yesterday i got this nice nozzle adapter in my hands. It’s an Samsung CP40 and i have to say, an amazing piece of work. The nozzle N045 (0.45mm) is made in plastic and the adapter in brass.
You put the noozzle only on the left side with the rubber rings, thats all and this system are airtight. The spring is in the adapater and this make the noozles very cheap ($5).
I guess my runout Problems with the JUKI Adapater are gone, cuz i’ll use Samsung CP40 in future. I need only a delron(POM) adapter to install this on a 5mm hollow shaft.
I am expecting my prototypes to arrive later today. We will compare.
@Jonathan_Lussier we have a version designed for the M8 threaded shaft nema11 stepper, and if we were to get a nema8 threaded with an M5 die, that could be easily arranged as well.
@Frank_Herrmann if its too hard, you may be able to heat the end of the shaft red hot first and let it cool to anneal it but you may burn your motor at the same time
