Thats the one. For stock E3 hot ends? I just ordered a micro-swiss kit that moves the ejector to the carriage and changes the hot end design to kill the leakage. Better design although I think I have finally got it sealed, well enough it isn't spitting out plastic down the nozzles threads. For about 4 hours, I have the last piece working at 300% of the speeds set in cura. Other than the fan vibration ripple in the laydown its looking good, and w/o that si rubber sock. Slow to heat the ejector though, and it would not ever get to abs temps w/o that sock. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
