Quoted from Rdoyle1978:Glad you guys are getting good results with an Ender 3 - I can get maybe 1 successful print out of 10, and spend endless hours re-leveling the bed constantly. I'm about done with it. Yesterday I printed a flat plate with a design on it for my kid, and I went to print a second one after letting it cool, and the second one - with NO physical or slicer changes, failed. I'm pretty sick of messing with it.
I was having the same first layer issues with prints randomly releasing, and upgraded to this build plate instead. Best $20 you can spend.
You'll need to adjust your Z stop, but once dialed in it's really night and day vs the stock plate. It holds with no tape/glue/hairspray needed, and once it cools below 30c you can lift the print off like it was never even attached.
