Got frustrated with the printer knocking over the parts of the T-rex jaw before they were joined at the mouth, so I taped them to the bed in mid-print. Is this cheating? 
No such thing as cheating in maker world.
Sounds brilliant to me!
When I was printing my yoda test, the bottom warped enough for it to rock a little during the print, so I used my 3d Doodler to ātackā it in place to stop the rocking for the rest of the print
Iv done this on more than one occasion. Better than wasting a print.
You did what needed to be done, there is no nobler action. Kudos.
I have used superglue in the past on glass for parts with small contact areas. There is no cheating if the part works.
Just paused it and then taped? You are so lucky! Anytime my printer has error it has been a stragly piece of plastic that destroys any chance to continue the print.
If you are watching it closely enough, you might be able to catch it before it gets to that point. One thing I plan to do as I improve my printer is to add a camera routine that will try and detect unwanted print movement and if it detects over a threshold, itāll autopause and raise an alarm
No pauses, just worked on one piece while the extruder was printing on the other.
From my experience, once a side gets wobbly or bumped, the game is over. I havenāt been successful recovering failed prints. For this print (and likely the top of the T-rex skull which Iām going to print next) I suspected it would be hard since there is very little surface area in contact with the bed/tape and a lot of tall, angled shapes.
I love that camera idea!
did the same on the same object! i usually put some tape if the base is littleā¦too many hours if it fault printing 
I find that applying and rubbing some rubbing alcohol on brand new tape makes parts stick ātoo wellā. I havenāt had to do the extra tape anchor yet.
