Conversation
+ Incorporated changes required to work with my printer, as well as auto-tune PID values. + Synced some changes from CrealityV427/Configuration.h as well as config/default/Configuration.h as made sense. + Synced some changes from CrealityV427/Configuration_adv.h as well as config/default/Configuration_adv.h as made sense. + Added more details to CUSTOM_MACHINE_NAME in CrealityV427/Configuration.h to make easier distinction between v4.2.2 and v4.2.7. + Created new configuration file for use with official Creality BLTouch probe. + Contains correct #defines set as well as probe offset from stock hot end.

I compared the various Ender 3 Pro config files as well and settled on similar set of changes so it would be nice to get a version of this pushed to save others some time. I'll add a few comments where I came up with differences. |

All the configs have 115200 and this assumption is baked in to lots of external apps so I'd leave it at current value.

Makes sense. I'll change it back.

If you use something like Octoprint to help automate filament load/unload or use Marlins built in version then this value needs to be at least 600. So in this case, I think its V427 config that needs update and not V422.

I can make a change to both config files, set it to 600, and maybe include a comment specifying why the value is what it is?

93 is the correct value for the stock extruder with no bowden tube connected. I'd leave at existing value.

The 111.2 was the value measured on my printer, but I can set it back to 93.
