Add filament while printing?

Can I add filament to my mini, by feeding the new filament in the tube?
I would like to finish a print, but I may be a little short.
If I keep a little pressure on the filament, would that work?
This is w/out an AMS-Lite, single spool.
Thanks

Yes. Once the filament runs out it will beep, push the new filament to the hotend & purge.

I’ve done it many times on X1 without AMS. Just keep the new filament in contact with the old until the extruder grabs it and the printer never knows what happened.

once the intake tube beeps thats its run out, insert whichever new color you want

Will it then say, press ok, then start printing.
Or will it ask to purge like lion7718 said, then start printing.
It’s a 7 hr. print so I don’t want to mess it up, I have more black coming.

If I’m on top of it, I can just feed the new filament behind the old like byMH62 says.
