What are you missing? THe Orange Pi is not a microcontroller. It is a
small size PC. It runs Linux and acts like a PC,I microcontroler is a
single chip with a much less powerful CPU and memory measured in Kilo and
mega bytes, not gigabytes. And
An Orange Pi has an integrated microcontroller that may be used for
stepping to >400KHz. It already does what you are mentioning internally.
I haven't explored how fast that it can read encoders yet for closed loop.

Honestly asking, why spend the time?
Did a PC abuse people in any way during the 00's or maybe the 90's?
The Orange Pi is generating steps >400Khz and runs LCNC for cheap and
is not a PC.
I'm looking for pathology to support a theory for anti-x86 PC machine
control sentiment.
What am I
Another idea is >1k harmonic drive designs for download in many native

Download in the format you wish. You have the native files so you can
modify to your hearts desire.

FFF/FDM is inherently slow and low res. A resin printer can make those
parts in minutes. The slow and cheap resin printers are under $200 USD
and print an entire layer 100um thick from 4-20 seconds

And it's still USB. Can it handle a 2500 line quadrature encoder? The
control is the small part of the overall CNC conversion. I found that buying
the CNC Cape for the BeagleBone which all around seemed like the lowest entry

Some have reported using Lithium grease for over a year without issues.
The water content might be an issue over time but you're probably not
looking at years of service on the gears anyway.
It's really not a big deal. Engineering and science is full of math
operations that you have to jump to all the time. If it is too difficult
find someone else that is not a complainer to help you.
