Do folks wire one per axis or two (max and min)?
If only one, where? Max Min on Z, left vs right on X, etc?
I only use the min so I can home consistently to the same place. For the max values I use software limiting. As you face the printer from the front the min X is on your left, the min Y is closest to you, and Z of course is on the build plate itself.
BTW, I was surprised to find that my local Radio Shack did have roller microswitches. Not a great selection, and the prices were about 3x what I paid at Allelectronics, but in stock. They even had the Arduino Mega2560! Still mostly phones, batteries, and R/C toys, but it looks like they are at least making some attempt to attract the maker community.
