A few questions about Pronterface and printing:
1. Is it necessary to perform the Auto-Home and Auto-Level operations before starting a print? Or do slicing programs automatically include this at the front of a print file?
2. What is the GCode command for Auto-Level? I'd like to make an Auto-Level command button in Pronterface, but need the GCode command to do this.
3. In Pronterface, what does the center red button do?
4. In Pronterface, does the Motors Off button turn the motors off for good, or just stop them? In any case, once this is clicked, is there a way to turn the motors back on?
5. Is there any benefit to printing from the SD card as opposed to printing directly from Kisslicer (or some other slicer software)?
Thanks in advance for any answers.

1.yes or no.
Use the kisslicer profile on file area. check the pre gcode.
The marlin FW here, g29 save the leveling array.
So, the g29 is not necessary on each print.
But might need bed offset. The example profile is work like that.
But you still can use old way, add G29 Z+0.3 (for example) after g28 at prefix gcode section in kisslicer or other slicer.
2. G28 auto home
G29 auto level

3. Possible G0 X(200/2) Y(200/2). [if you set the dimension in pronterface setting]
It looks like not for deltabot style printer.
4. Turn off,no motor current out put.
You could notice that you can move the cart by your hand.
Any G code need to use stepper motor would bring it back output and moving.
Such as G01
5. SD card benefit. No PC connected required.
Prevent any USB connection or PC sw error/suspend interrupt the printing job.

1. Yes for auto home, home is the starting point to count the distance to the bed. No for auto level, it is now stored in eeprom, if you did not remove the bed or disassemble the nozzle parts, it is not necessary. They are stored in your prefix gcode..
. 4. Marlin firmware has a timeout to turn off motors but you can manually do it by click motors off. Turn off means power off, do not energized them. once you give any command related to move, the motor is turned back on automatically (Ex. G28 auto home)
