Suddenly having instable prints, help!

Hi all. I've been using an i3 MK3 for a while now, and it's been working absolutely fine with no issue. However, recently I've ran into some issues when trying to print anything that isn't one giant blob. If the print is a big mass, it'll print decently, but with smaller things it'll just absolutely fail.

I've done a full Wizard calibration already, and have done first-layer calibration numerous times, both setting it to a medium height and a farther-down height. Both failed, and the latter ended up 'flakey'.

I don't really know what to try at this point -- this persists across both the smooth and textured beds as well as isopropyl alcohol cleaning. Any help would be greatly appreciated.

The chances are that your build plate is not clean enough

IPA may not clean the build plate satisfactorily. 

I Wash my build plate with a New dish sponge, hot water and a little dish soap, rinse well with Hot Water, and dry immediately with plain paper towels

I also use 7x7 mesh bed levelling, with Magnet compensation enabled. 

I use "Life Adjust 'Z' My Way", by Jeff Jordan

RE: Suddenly having instable prints, help!

the first layer is way to close i dont know if it will fix the adhesion issue but you could try to put an extra 5-10 degrees extra heat to the bed
