I have a Ultimaker original and I have put the second extruder on but the second is much higher than the other and when I losened it alittle it stated leaking I cant tighten the other anymore to make it higher I was going to try heat proof lock tight and make it so I can loosen it with out leakage to make it level but I was wondering if anyone had any ideas first and I have also tryed Teflon tape aswell.
