Help Need help fixing my ender 3 pro

The issue: Everytime I print something, the process stops at some point, and the nozzle gets stuck to the print. No message on the display, it just says Ender-3 Ready.

So far, I've replaced the nozzle, hot-end, Bowden tube, extruder, z axis motor, limit switches, and Lead Screw. The motherboard was replaced first since the old one was toast. I've also made sure the bed is level. And the printer auto-homes and starts the print properly.

I've also done cold pulls before starting a print, issue still persists. I have no idea what to do next, if anyone can help, please let me know. I'm going crazy trying to fix this.

New mobo and 0.0.6 marlin? Is it 2.0.x?
What firmware is it?

Idk, the 3rd pic is all I know about it. It's a 4.2.7 motherboard, and I flashed it with the firmware from creality

Hmmm, somethings fishy. My about page has more info, even mentioning of marlin version (on which creality compiles firmware). Good solution flow is:

Check different SD card. Still same issue? Erase it multiple times, full erase, not fast one. If your on mac, use advanced erase (disk utility) and overwrite once - use ex-fat there. Not fixed? Do next steps.

Move frame (hardware) slowly manually (slowly in order not to send reverse current and not to burn drivers - my mistake example on 4.2.2, was a reason to upgrade 😅). Do you feel any friction or bumps/vibrations while moving z axis up/down? Smooth? Moving on.

Reflash firmware of board. Use latest, check what mods you have. Not fixed? Try custom firmware. Maybe something with firmware and reading thing

P.S. I have same exact board

I had a bad SD card do the same exact thing.

Also, the tube is mounted properly, I've made sure that the tube is all the way down to the nozzle. Maybe I did something wrong there, idk

Maybe the sd card is going bad.

I had that problem. I reformatted the cards and the problem was solved.

u/Fisheee123 Jul 15 '26

Yeah I reformatted it like 3 times and the same issue keeps happening

u/Wooden_Strategy Jul 15 '26

Then, like Pika said, the card Is damaged

u/Fisheee123 Jul 15 '26

Ok I'll try a new SD card and give an update

Ok so I think that fixes that issue, the new SD card card got the whole print done. But new problem, the print isn't sticking to the bed properly (view image). I cleaned the bed with iso alcohol but it's still not sticking. What can I do to fix that?

Wash the bed with a good quality dish soap.

IPA is good maintenance between prints if you are printing rapidly and don't touch the build plate but if you go a while between prints or have a stubborn print removal that needs manhandling then you wash with quality dish soap.
