Pause during carve

I appreciate this thread. It appears, regarding the controller and display that it is ok to pause for extended periods of time,. Just be safe and turn off the router!. In another thread, users were discussing the stepper motors and if they were “holding” a position (micro step etc). Anyone have any comment regarding the stepper motors and pausing for extended periods of time. Heating up?, losing position, etc?
I have had my X50J (BB) for a week. I do 10 hour 3D carves. I also work, sleep and have neighbors who would like to sleep. So, pausing for extended periods will be necessary.

Also, there is some discussion regarding the display not connecting if it is not turned on before the controller. Is it likely that if you turn off the display after pausing, the display may not re-connect when you turn it on again?
Thanks.
