@Demontrich so I was hoping to get that deep of a vacuum, haven’t been able to achieve, not sure if it’s because of hosing, leaks, or even my pump whether the sogevac is strong enough to get that deep of a pull or if I need it rebuilt or something. Ran it blanked off this morning. Got 580 micron on it. Decided to change oil again before I run second pass, got down to about 380, so I know the pump itself isn’t quite up to the standard we’43 trying to achieve.
@Cryo13 what was dumping was definitely terps. All the etoh was stripped and material was fully decarbed at that point. Two reasons it started dumping terps like that is 1: because of the shorty head having less path to travel, it flows pretty well. And 2: because I had turned the system off and changed pump oil, then re-engaged vacuum on the system which ripped off the first part of the terps pretty quickly. Essentially made that fraction jump through, sort of bump over from going from atmosphere to running vac pressure at that temperature.
@Killa12345 how should my vac gauge be situated to achieve accurate readings?
