⟨patrikcath⟩ I don't think that's the issue. I'm doing a more casual run without RO at the moment, so instant ignitions and throttle 0-100, and when I tried to execute a principia node with MJ it was horribly inaccurate. I think it burned for way too long
<queqiao->
⟨jk gibbs⟩ what is the version of principia for 1.12.3?
<UmbralRaptop>
per the readme: "Hurwitz, the March version of Principia, is available. Download it here for 1.8.1, 1.9.1, 1.10.1, 1.11.0, 1.11.1, 1.11.2, and 1.12.2 to 1.12.5."
<queqiao->
⟨jk gibbs⟩ it says its for 1.12.5 not 1.12.3
<queqiao->
⟨lpg⟩ "1.12.2 _to_ 1.12.5"

⟨Al₂Me₆⟩ (And enumerating all supported versions in the filename would be rather too cumbersome...)

⟨kingparity⟩ is there a way to access the rotating-pulsating frame / will there be?

⟨Gratak-⟩ The MJ prinicipia execution is actually surprisingly well implemented:
<queqiao->
1. If it starts late (ullage problems, didn't manage direction in time or simply pressed too late) it keeps going after the maneuver ends and keeps pointing (mostly) in the right direction
<queqiao->
2. It can actually handle in-maneuver staging decently. You have to stage manually and it will be off more then otherwise, but it does the right total burn time (increased if the next stage has lower twr)
<queqiao->
3. When none of those problems appear and you set the tolerance in accordance to your twr, it is very precise
<queqiao->
⟨Gratak-⟩ * twr). I actually use this often when my departure stage is a bit too weak since there is no good way of setting up two nodes for this in principia ahead of time and you'd be wasting precious time near earth if you do it in between the burns

You do...
<queqiao->
... waste one ignition this way though (as the correction burn will usually require the main engine again in this case)

⟨kingparity⟩ trying to build principia and it's telling me it's missing the Google folder, I assume that's all the google libraries listed in the dependencies but I'm unsure how to install those
