@spauliszyn : Did you ever figure out if you need M420 S1 or not in Cura ? I've got the same question.. and it sadly doesn't seem to have been answered anywhere on the forum clearly.

RE: Bed Leveling doesn't actual level the bed
@bucweat did you ever figure out if you need to do the M420 or not ? I have the same question.. not sure what to put into my Cura (4.8) default profile! Would appreciate learning from whatever you've experienced !

RE: How to autolevel?
A question that has not been answered here still is this: is ABL on without an explicit M420 S1 command ? There's lots of warning in the marlin firmware documentation that a G28 disables auto-bed-leveling and you need to turn it back on afterwards.. i'm getting mixed messages about whether it is required in the preamble G-code for your slicer.
Would appreciate advice here from either the community or @admin !

RE: Is auto-leveling persistent?
@BD : To clarify here, what's the recommended setup and GCODE when using something like octoprint / Astroprint to print via tethered USB ?
- You should leave the SD Card in there
- You should level the bed via the LCD
- You need to do "something" to the standard Cura GCODE to get ABL to take / not be ignored ?
Step 3 is where i'm missing something. Right now, as of the latest Cura, with the built-in CR-6 SE profile that's now included, I have the following start / stop GCODE... is using this profile and then printing via Octoprint (or any other method) ignoring the benefit of ABL by using G28 as it is ?
Does it really matter if I send this GCODE via Astro/octo-print or via SD card? I would think it would be the same, no ?
