Yep, well said.
Dan, there is actually both a high and low vac on the unit and both are a critical component that needs to be dead nuts on. It's a necessary evil as the wax would weep out of the print head without the vacuum balance but if it spikes too high it wants to suck wax back into the system's lines. This was the actual issue with the prior analog controlled system, not print head clogs per se, it just needed that digital control to keep the molten wax where it should be. Bonus is that tech support can log in remote and adjust it should that be required.
