Hi all,
I've been a member of Zealot for a very long time but haven't been active for about 10 or so years. I was invited to share my 3D printing experience and I will make a better introduction in that section.
I bought my first 3D printer, an Ender 3 Pro about about two years ago. Actually, the one I'm using now I bought about a year ago but it has been in storage for six month before I unboxed and assembled it. Had a pretty steep learning curve since that first printer. One big problem I have that seems to affect most Enders is that the printing bed is not flat; it dips in the center. I saw a YouTube video on this and the guy had a good fix. He uses Post-it notes to build up the middle to get a better flat top that the magnetic bed sits on. Worked GREAT but I wanted to use something else that was not paper and transferred het better.
I decided to use aluminum foil. I used gradually larger circles stacked on each other to spread out the lift. In all total, I have 5 circles from about 3" diameter to just inside the limits of the bed. I had to deal with the foil moving around when I lifted up the magnetic pad from the bed. I used a VERY tiny drop of super glue between the circles (1 on each quadrant) and not there is virtually no movement when I lift up the pad. If it does shift the whole stack moves together and is very easy to reposition.
Hope this helps!
