It is kind of useless to do 0.0001 to measure backlash because most of the time the steppers doesn't even move. This is a Series II machine, so I wonder why isn't 0.0005" supported?

While enabling the network this morning, I noticed the MDI packs some secret messages. Of course, chances are these won't be divulged as this way we can't tinker with PP. Or have these instructions been made public somewhere? Maybe there is one to configure the step rate increments?
