I have recently made my very own first 3D printer (Prusa i3 replica) using a RAMPS 1.4
I have been facing a serious issue with the power failure in my locality, which ruin all my prints, I basically could not afford a power back for the printer.
is there a way I could resume my prints when the powers back? Through Marlin or any other means?
also, I don’t know y my prints shrink to the once I upload through cura, have I done some error in Marlin?

With Ramps, resuming prints are not possible. May be with some other board it can be possible. A small UPS will give a minimum of 20-30 mins back up.

Shrinking means, when it print it shrinks or how?

You’d need to change your board…
