I'm helping a friend converting a mill and all this servo stuff is new to me, so I still have a lot of questions I cannot find the answer here..

What is the best approach for homing? Using micro-switches and the encoder z output? Or there is no need for accurate homing.

How to wire the e-stop? For steppers I cut the power to the motor but here I have e-stop input at drives as well as controller. If I use the e-stop this way, the machine will not lose its position, and I can continue the work without homing the machine. Am I right?
