The trick is to cool the thermoplastic just enough that it won't sag and fall
over, while remaining melty enough for the next hot layer to fuse to it. Has me
wondering if 3D printers could have an extra bridging fan, a small one with a
precisely aimed nozzle that could quickly turn on when

That might explain a problem.The purpose of the fan is not to cool the
nozzle but to
The "nozzle fan" is actually a "part fan", used to cool down some plastics,
especially PLA, that have a low (50c) transition temperature. Cooling the
nozzle, and heat block is bad; that's why they make silicone "socks" to
cover the heat block and nozzle.

How to calculate the accuracy of the resolver?
1.Does this calculation make sense?

2. And if the gear ratio is made 1:5 ?
