To add a little bit to this, check if the motor gets hot. If it's not hot then you probably don't need to worry.
In addition to what has already been said, personally I use auto-home and then move the hot end to the middle of the bed (On my printer, after auto-home it is the ABL sensor that is in the middle of the bed) and then set the Z position to 0mm.
Then I go change the Z Offset setting until it touches the bed with the paper like you did.
In theory I suppose the result should be the same but it might be worth a try if what has been already suggested by u/p1mrx is not your problem.
Just subscribed to Lemmy.world because of the message in Sync for Reddit, so I'm definitely looking forward to buy your app again. Still not too sure about the differences between Reddit and Lemmy, other than Lemmy is slow, but it's probably getting a lot of attention suddenly.
