Sure, once you have it dialed in to the best click on the encoder, it should
repeat quite well, except for thermal expansion.

I am amazed that you guys use wire nuts, they look so gimcrack
compared the the screw clamps that are mandatory here.

Andy,
I had the priviledge to learn home electrics at Muskegon High school in
1966 when I was an exchange student. I could have started a career as an
electrician right there but, even at my age of 17, I realized that there
must have been a lot more to electricity than what I had learned so
