Stuck in a cart-before-the-horse situation with a new MK4S & MMU3 initial start-up...
MK4S & MMU3 pre-built unit arrived, assembled the MMU3 hardware and reached the first time turning on the printer stage... Printer initialization started, self-test of bed heater, nozzle sensor / heat, X, Y, Z axis, etc... Got to the last stage of the set-up where you're asked to feed filament to test / calibrate the sensor. I can't feed filament through the MMU3 to the print head because the MMU3 isn't active -- I go into settings and see it's disabled, but when I go to enable it, it tells me I can't until the filament sensor test is completed.
I feel like I'm back in the early 90s trying to install a CD ROM drive, only to find out the drivers for it are included on a CD ROM!
How can I finish the filament sensor test / calibration without a powered MMU3? Do I force the MMU3's selection head manually in an attempt to get the filament to feed to the head, or do I have to rip the pre-installed feeder tube from the printhead to shove filament in?

Calibration of the filament sensor on the printer is done without MMU3 enabled! Disconnect the tube leading from the Nextruder to the MMU and insert a piece of filament directly into Nextruder for calibration purposes.
