Just got my Snapmaker V1 and am advanced in 3d printing (own a prusa i3 mk3s, ender 3, ender 3 pro, nwa3d a5).
For the life of me i could NOT get the filament to stick no matter what.
I bout a sheet of PEI, the same stuff that my prusa bed has covering it. It costs around $15 on amazon. Very simple to put on. Just peal off the snapmaker pad, clean the bed of any glue or debrie with denatured alchol, and apply the pei sheet with nitrate gloves.
here’s a link to what I used if your interested
I’m working on a youtube video(s) of my experiences on my channel here:
