3D Printing Forum

I have a ender 3 pro. The first print I did it work great. Now every print I do the print won’t stick to the bed. I did the tricks they show online like using a glue stick. It started to work and about 5 minutes into my print the Print came loose and moved with the printer head. The bed is level and I got a automatic bl leveling on it too. The nozzle heats up to 200c and the bed heats up too 65c. I am using pla plastic. After the bed heats up I can still put my hand on it and it just feels very warm. I see when the plastic comes out it get soft hard before it hits the bed and semi sticks to the bed or just starts to slide around the bed. It came with a 0.4mm nozzle. Thanks for the help I get.

Some advice as follows -

PID Auto Tune the bed and hot end

His site has a lot of other great calibration tips I would suggest you check out. Usually 65C for printing PLA is a bit on the warm side but not terrible.

I'd also make sure that the bed surface is clean, using rubbing alcohol to completely clean it.

That's a place to start
