One thing that stuck out to me was the dive speed of the BLTouch. 500 is quite high for the BLTouch. For best repeatability try 100.
Which wheels did you replace?

@Phaedrux
Carriage has 3 wheels. 2 in top and 1on the bottom. The bottom one is the one I am holding. It's harder to see when on the printer but when I got a good look at it I hoped all my problems were solved. Nope. So I replaced the other two on the top just because I could/easy to do. Bed level issue still exists.I will try changing the setting you mentioned. Thanks.

I just ran a quick first layer few layers test and it appears to, at the very least be better then it was. Its weird if just slowing this down fixed it, (now its sooooo slow.....!) but do have an idea on why I have this problem now, as it was working fine with the settings before I moved the Z screws...The BLTouch/needle is able to hit one of my screws when moving along the wall. It bent the plastic needle but wasn't bad as I just had to straighten it out with my hand. That may have let to this issue happening, even though it didn't show until after the Z screws were moved, or it just hit it again, and much worse after the Z screws were moved and I didn't notice as the needle is moving freely this time. I do plan to get another needle but can't imagine paying for shipping for 1 small cheap item if it is still working as is.
Thanks @Phaedrux!

Yes it's a bit slow. To make homing a little faster I use M558 F in the homeall.g to change the speed of the first probing dive to be fast, and then change it again to be slower for a second dive.
M558 F400 A1
G30
M558 F100 A10
G30That way it will move to the bed quickly if it's far away, and then probe again more slowly for better accuracy.
That wheel certainly was chewed up. Over-tensioned?
That sucks about the BLTouch pin. I've damaged one myself by getting it caught on the edge of the bed. I wasn't able to get it bent back and just replaced the whole unit. The trigger sensitivity of the pin could be out of whack from the collision.
-
I will try to get it to go fast to start playing with the code you shared later today. Thanks.
I don't know if the wheels are too tight as I stop tightening them when they are no longer loose. But it wouldn't take much to over tighten them. Almost all of the wheels on my printer wear some, but have a better view of them... So I swap them out if needed. Most are still original...

@Phaedrux
Weird thing about it being out of wack is that it's very consistent. Just not level. -
Did the collision happen to tilt the BLTouch mount?
-
@Phaedrux
I don't think so. I believe it is the same as it always was because I mounted it with the springs it came with. Depending on how it hits something, it will move and then go back to it's normal position. -
So... It appears going slower just makes it more accurate, and helps a little bit (that is noticeable) but the issue still persists. I have to stop actual test prints to get my quality back tuned in (since I replaced the wheels, its been off) and just test this bed leveling issue.

Thanks That makes more sense now. Will be easier for me to use in the future. And with that knowledge.I think my problem wasn't as much baby stepping as Auto Bed Leveling. Auto Bed Leveling no longer makes the bed level. One end is always higher than the rest of the bed, and this happens every time the same way. As such, I think it's working, but having trouble, troubleshooting it. This start after I moved all of the Z screws, but have already remeasured their current location and updated the config.g file. I have to be missing another step I took when I initially setting up auto bed leveling as it was working perfectly without any fuss. It was like magic. And not struggling. (I had to move the screws as the bed/mounts was hitting the stepper motors on the way down).
Thanks!
I think it might be worth starting a new thread with your auto bed leveling issue to get some more eyes on it. I don't use it myself, so maybe someone else has some ideas. include your config and homining files, etc. There's gotta be some reason it was working fine before but isn't now. We've eliminated some other issues, but I'm not sure where to look next.

Thanks for your help @Phaedrux.
I may start a new thread later, but you were able to help me make it work better (more accurate) and now if I lower the first layer height a tad, its no longer a big deal. After you mentioned slowing down the speed to find the bed, and I saw it was more accurate, I tightened down the screws/springs on the BLTouch and that seemed to help a small amount too. Not as much as slowing it down but still.... I just need to get back to printing some test prints to test multi color out, to see if it would be good enough for Christmas gifts. Or if I should just print one color and paint...
