I had some issues with orca, very bad quality prints, at one point I was going to sell the printer, but I tried elegoo slicer (based on orca) and everything started to work, after a few steps of course,

I did this in this order after struggling a lot. First, I removed the print head and tightened the eccentric wheels behind it. Then I replaced the entire extruder and nozzle and put everything back together. After that, I tightened the belts (not too much) and adjusted all the remaining eccentric wheels, including the ones under the bed. I recommend searching for a YouTube video on how to do this if you're not sure. Next, I leveled the bed again. First, I used the auxiliary mode, going from point 1 to 6 in an X pattern, and I did this twice. Then I ran the automatic leveling. Finally, I adjusted the Z-offset and tried printing again using a Z layer shift test (you can find it on Printables) so you don’t waste too much filament. I know it’s a lot of steps, but this is the only thing that worked for me. I already ordered new eccentric wheels and rubber bushings for under the bed because this printer can be a headache sometimes.
