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?

I usually do full expansion/full liquid but if you have a short prep you could go 2ml water/21ml liquid. Usually 1-2ml of water is all you need.
