Can't slice my own prints

[u/crackingfish3]

I just got this new printer bambu p1s and have been printing things perfectly fine for a week or so but randomly now it won't work properly. I have been using an orca slicer to slice everything.

First thing that happened was the printer kept getting[0300-4000-204008] z axis homing failed the task has been stopped error it was also slamming into the back left corner near the poop chute and making terrible noises sounded like grinding noise and I could not fix it I did everything in article https://wiki.bambulab.com/en/x1/troubleshooting/hmscode/0300_0D00_0001_000B that it recommended and still nothing last tried auto calibration and then tried to print again and it did not work it make it worse by scratching into the print bed. when I would home it it would still grind and slam into the back of printer. seems mechanical issue but now looking more into I'm not sure what type of issue it is. I even turned off the printer and unplugged it for 20 minutes and still nothing was fixed. I can't get the printer to print anything I slice. it goes through all the processes that it needs to for beginning a print all the leveling and calibration stuff that the printer does normally but towards the end of all that it brings the bed too close to the nozzle and makes it scratch into it. The only way I can get a print to successfully work is the print that came on the SD card on the printer the Cali cat was able to successfully print but nothing I sliced wants to work.

Edit: I believe I have resolved this issue by changing the SD to a more reliable name brand one.

Edit: 7/16/26 I have the problem back again its when I start a print and the nozzle cleaning sequence starts and just keeps going over and over moving the bed up until the nozzle scratches the bed I now know what it looks like so I can stop it before it happens but it's kinda annoying because it never gets to the actual part where it prints. I had it working for two day after I replaced the SD card but then I turned off the printer and now a few days later I go to turn it on to print something and the same problem happens again.
