You can abort I think within the TUNE menu. I didn't check, sorry.
So it looks like you had a layer shift to the left. If you look carefully you can see that most of the part printed fine for several layers then it looks like the part is duplicated (in a silly string kind of way _ to the left. In particular there are 2 ear hooks and the wavy-string stuff is to the left for both ears. About 1.5 inch to the left.
OIL
There are a few possible causes. One is that you just need to oil the rods. With power off push the print head around to the 4 corners. The movement in X and Y should be about the same. You should not be able to push it with one finger but if you use one finger on each hand, try pushing with one finger on each end of the rod going through the head and it should be easy to push it (printer might slide a little on the table but usually not).
If the X axis is much worse then this may be the only issue. Anyway use some oil to clean the rods with tissue or paper towel and then after removing all oil add only one (one!) drop to each of the 6 rods in the gantry. Push the head around. If you feel an improvement you might be done.
PULLEYS
More common (maybe - well quite common anyway) are loose pulleys. They may be fine 99% of the time but when there is a little too much acceleration they can slip. Each of the 12 pulleys have a set screw. Your printer should have hopefully come with a long hex driver with a green and black handle. You need to tighten all 12. Actually just the 6 on the X axis. The 4 pulleys on the long belts are easy with an L shaped allen wrench or the hex driver. Just push the head around until you can see and access the set screws. However the most likely pulley to slip are the 2 on the short belts on the X axis (which are the X axis? just push head left and right and you are moving X axis belts and stepper motor).
Those 2 pulleys are the hardst to get to. If you have a hex driver you can do it without taking anything apart. If you absolutely can not make phone calls and get access to a hex driver (2mm hex driver) you will have to remove the cover over the X stepper. There are I think 2 screws holding each stepper cover - screw head is outside printer. Only uncover X stepper (right rear corner). You may have to completely remove the stepper to tighten the pulley set screws. I have never had to do this as I have a long hex driver.
TIGHTEN THE HELL OUT OF THESE SET SCREWS! You want it scary tight. So tight that the tool twists. If you are using an L shaped allen wrench it should hurt your fingers. You should see red marks on your fingers after from the short length of the L.

1) Please take a photo. I have no idea what you are talking about. Microfibers?
2) You can just hit the power switch if you want. In the pause menu I seem to remember an abort option. Anyway then just clean things up and start over.
3) PPE is complicated. Are you sure you will be printing a design that will actually be used? There are lots of problems with many of the designs floating around out there. Did you speak to a doctor? Are you printing a design that multiple nurses or doctors approved of. It's great that so many are helping but let's not create things that won't get used.

Thank you for your response gr5. I attached a photo when I should have done that before.
I did not see an abort option. I saw "resume print" "change material" and "tune"
So I ended up resuming the print job and will try again.
Thank you for asking about the PPE. The person in charge has given out over 150 face shields already and Rhode Island
Hospital called him and is asking him for more. It's not junk 3D material and if it was I would also try to stop the process.
With the lack of federal help, more librarians and teachers are volunteering to print the parts that are needed to make face shields.
I really do appreciate you getting back to me so quickly. I am reading the manual and learning a lot. These printers are amazing.
Thank you and be safe.
Here is a link with a student explaining the process.
