@Phaedrux said in BLTouch Bed leveling oddity:

The reason for going to 3.0 first is ...

Makes sense.

The json file is a one way street.

I suspected that when I used my last old one and a lot of it wasn't what I had done manually.

The configurator is a jumping off point, .... it's best to just get used to modifying the config.g directly.

That was becoming apparent this time. It's fine when I'm all mired in it, but not touching it for over a year ... "You don't use it, you lose it!" Gets worse as I get older too. Grrr. LOL

Using the endstops as an e stop is perfectly fine idea. You can also drop your Z axis motor current during homing/leveling so that in the event of a crash there is minimal chance of damage which kind of negates the need.

Just like the idea of a backup plan, the BLTouch can be cranky.
I toyed with the idea of dropped current but never got around to it. Good idea, I'll do it now until I'm all squared away with RC 2.8 Milllion. Poor David, every time he thinks he's got it nailed some major buggy-boo bites him in the ass! Guy's a Saint.

Thanks Jason, you always get me back on track, your work here is truly appreciated. 🙂
