The horrible "machine gun" noise happens when the stepper "skips" steps. It's a magnetic thing and although it sounds horrible your printer should be fine. All the mechanical parts are stronger than the maximum force from the steppers.
If you power off and one axis is stuck then you have a serious mechanical problem. I've seen this when sugar water, candy, glue, glue stick, or hair spray gets on the shafts but it could be many causes. I recommend you start taking it all apart. Loosen the 4 pulleys for the bad axis. Completely pop out the two shafts that go through the head and put the head aside somewhere. Try to figure out if a shaft won't turn or more likely if one or two blocks won't slide along one of the outer shafts in the gantry.
It could be as simple as LED wiring caught in the belt/pulley system.
If you printer is very new, you could try warranty service with your reseller but this printer is meant to be taken apart somewhat. Certainly the gantry isn't too hard. If you take apart one of the 4 slider blocks however be very very careful. Those are easily destroyed (replacements are very cheap but who wants a "down" printer while waiting for replacement). So pry those open very gently.

Strap in for the first Cura release of 2024! This 5.7 beta release brings new material profiles as well as cloud printing for Method series printers, and introduces a powerful new way of sharing print settings using printer-agnostic project files! Also, if you want to download the cute dinosaur card holder featured below, it was specially designed for this release and can be found on Thingiverse!
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
