Microetcher solving no powder problem
Occasionally users report that only air is coming out of the Microetcher nozzle with no air. There are a number of possible reasons.
The most common reason is due to the handpiece nozzle not being screwed on tightly. Without the proper seal that this creates it allows just air to come out of the nozzle with no powder.
The seal may also not be complete if an o-ring is missing or the grub screw in the little hole at the nozzle end of the barrel is allowing the part holding the nozzle to turn, thus preventing the nozzle from tightening.
Below are links to 3 documents that cover possible issues.
