I wanted to have a real motor/encoder system for my office EMC instead
of using a simulated configuration. So, ruined a surplus printer to get
the motor/encoder assembly, which I connected to an L298 and a +12 Volt
motor supply. When I got to testing it, I had a hard time with tuning.
On occasion,

You do not see this on good motors. You can check for this
with either a variac- or electronically-controlled power supply
that you can
