One stroke creates power - the other three do not... they eat power output.
Mechanical power out at the crankshaft = Power out combustion stroke - everything else (friction, heat, fluid restrictions, and a bunch of other stuff)
Power at the wheel = Shaft power - all kinds of friction and...
I did not miss any point... I worked on teams designing both Compressed Natural Gas (CNG) as well as Propane - both fuels are a gas when entering the combustion chamber and there's a minimal (negligible) increase in fuel milage per unit of heat energy converted into mechanical energy due to...
AKA, experienced, been around the block, heard the nonsense before, you can't fool me, etc. It's a introductory qualifier statement - old people understand this...
Let me add - I'm a boomer and a licensed Aircraft Technician (F.A.A Airframe and Power plant licensees) on top of that I'm a...

My short thought and contribution is...
UltiMaker Cura is free, I use the Lutzbot Cura version and am good with it. There's other slicing and programming software most appear to be good. e.g. PrusaSlicer, Slimplify3D and many 3D cad programs will slice and create the gcode you need with header...
Official wording in ANSI / AMSE B1.2
"NOT GO (HI) functional diameter is acceptable when the NOT GO (HI) thread plug gage applied to the product internal thread does not enter more than three complete turns. The gage should not be forced. Special requirements such as exceptionally thin or...
