So my e.max have been coming out a bit too loose on the die lately. occlusions are also higher after pressing too. I mill wax with jensen soft beige wax, seems to be the same stuff you can get anywhere and has that vanilla smell to it. Fits, margins are all good. I use Zubler 144 investment which is the same as microstar if your familiar with either. I follow the mixing and setting instructions. So should I do slightly different liquid to water ratio? I can't remember which way tightens, more liquid or less?
