Prusa XL 3D Printer
Uhh ... I hope I am wrong, but too often I have seen someone join a forum, only to post (as their very first and sometimes only post) a link to a custom product. Surely that brand new poster has no vested interested ... right? Surely we should not use the word "schilling" in such a situation ...- awake

Let's make a 4 cylinder flat
Actually, that sounds plenty challenging - between the 3/16" through hole and the minor diameter of the 1/4-28 threads, you have a very thin wall. Well done on only scrapping 4! :) Sounds like it was an "exhausting" day ... :)- awake

Building a twin cylinder inline i.c. engine.
Brian, I am too late on my reply - but yes, the "Steel Webster" that I made a few years ago uses a steel liner* with a cast iron piston and viton o-ring. I've never tried for an endurance test, but it runs fine any time I get the urge to start it up. *not a totally steel cylinder, but rather a...- awake

What Fillament, wall thickness and Fill Percentage for Patterns
You mentioned using a .2mm nozzle - this is going to be very, very challenging on any FDM printer. .4mm is about as small as I would want to go; anything smaller, and you are likely to spend more time unclogging the nozzle than printing!- awake

Help with Arduino idexer
Certainly, every increase in the number of steps available will provide a corresponding increase in the accuracy. One way to increase the available steps is to get a .9° stepper motor (400 steps per revolution); another is to half- or micro-step (with some loss of torque, so may need to beef up...- awake

Help with Arduino idexer
Mike, in terms of input, that is purely a matter of how the software is designed. As long as the display will accommodate it, you could design the software to input any arbitrary number of decimal places. Whether or not the system can resolve the motion to that level of precision, however...- awake
