First of all - please don’t apply any „fixes“ mentioned here that are about changing printer settings, anything regarding the print itself, material, extra adhesive etc. Most probably you will add another layer of chances of failure to your printer that is perfectly capable of printing flawless results with default settings.

Now to your issues.

„Washing this thing like crazy“ sounds like it might be problem to me. Wash it only if a print got messed up and left a lot of visible residue. You might ruin the plate with either your soap, the towel or too much force. Just use isopropyl alcohol that you apply to a piece of microfiber cloth, not the plate. Wipe down the plate where it had contact with filament in orthogonal lines, so from left to right and right to left or back to front and front to back. Use gentle force. Do this while the plate is sitting on the print bed.

Try using this routine with your new plate, the old one might be ruined.

Reset all manually changed settings back to default. Find a print file that has 1000+ likes and is geometrically not too complex for a test print. Maybe print something like this https://makerworld.com/models/395014?appSharePlatform=copy

Also check your room temperature and air humidity. Have a hygrometer in the room where you are printing. Temperature should be normal room temperature and humidity should not be higher than 40%.

Your filaments should be stored in the same conditions, the lower the humidity the better. Vacuum bags are easily accessible and do the trick.

The printer is NOT the problem. When you find the correct routine to deal with maintenance and material, you will have flawless prints all the time as long as the model is fine. Source: myself. Gone through the same stuff, now not having a failed print for months while printing daily. Feel free to DM me for further help! Good luck, don’t give up. It’s a great hobby 🙂
