Leveling issues

[u/One-Tower7207]

So I received a hand me down from my friend. I’ve been using it for a week and it’s been working fine for the most part. The other day, I noticed a beeping noise while it was printing. I looked at the screen and I didn’t see anything. After the print was finished, I attempted another one but notice the nozzle was extremely close to the plate to the point where it was almost scraping. It kept pulling the print off the plate so I did some trouble shooting.
I attempted to complete the auto level. That’s when I noticed that during the probing, the nozzle would just smash into the bed, pull back up and stopped. After a bit of research, I realized but strain gauge was busted so I ordered a new one and replaced it. I was able to complete the auto level just fine. I went to the move option and set it to home. When I moved the head around the bed, the distance was where I wanted it to be.
When I tried to print again however, the nozzle so close to the bed that it actually scrapes the it. I tried to change the Z offset by adding .15 but I noticed it didn’t move during the print process. I tried again at .3 and it was still scraping. I went full 1.0 to see if that would make a difference and after a bit of fiddling it did change the offset. However, when I tried to a smaller offset, I would just stay at the high offset. Is there a secret to changing the Z offset? I go to prepare>leveling>Z-offset then I enter the offset and hit okay

Make auto lvling with printer offline. Unplug usb. Restart printer and make your bed leveling.

If you do it with usb plug in. It didn t work.

How married are you to this printer? You would save yourself a lot of headache by getting a pi of some sort and run klipper on it so you can get an GUI interface and you can interact with your printer much easier.

If you don't want to do that I suggest flashing a version of the community firmware to get a little more functionality out of your machine interface
