Admittedly very annoying to automate in any meaningful way.
I automated my HP + Normal Large Turbines roughly by doing the following:
- Picking a the 'best' rotor that I could build. In my case, it was Tungstensteel Large since I had enough Tungstensteel. Your case might be different.
- Computing the LHE output steam flow rate to match that. Note that you can overdrive or underdrive the 'Optimal Flow Rate' of the rotor by 25% and not pay a penalty.
- Chipping the LHE to achieve that flow rate, making sure to stay within +/- 25% of the turbine Optimal Flow Rate.
- Matching the lava or hot coolant input to (slightly) exceed the chipping minimum, again making sure to stay +/- 25% of the turbine rotor Optimal Flow Rate.
The reason why I recommend starting at the rotor and working backwards is the rotor is usually the critical element that can't easily be upgraded/downgraded without significant infrastructure changes (improvements).
Also note the De-assembler in 18.104.22.168 and later can successfully return all/most/some of the used (worn) rotor parts. I'm using the 8192v version, and it is indeed 100% efficient, returning *all* rotor parts. I just have to re-assemble to get a brand-new rotor. This means really expensive, but really useful rotors are viable.
