[FR] MESH_BED_LEVELING for DELTA, etc.

[a4jp-com]

Is your feature request related to a problem? Please describe.

I tried to do a mesh bed level on my delta printer but there was a message saying it could only be done on rectangular beds.

Are you looking for hardware support?

Dream Maker Overlord Pro

Describe the feature you want

Please make it so we can do a manual mesh bed run on delta printers when they have with round or hexagonal beds.

Additional context

Message they are probably referring to

#elif ENABLED(MESH_BED_LEVELING)
  #if ENABLED(DELTA)
    #error "MESH_BED_LEVELING is not compatible with DELTA printers."

Yes. That error message.

Sorry I'm not up to date on all the changes here yet. The last time I worked on Marlin software was back in 2016 when @thinkyhead @boelle @Wackerbarth etc. were all active. I'm gonna try updating my Scoovo X9H and Dream Maker Overlord printers to Marlin 2. I'm using the latest test version.

Try using AUTO_BED_LEVELING_BILINEAR with PROBE_MANUALLY or use AUTO_BED_LEVELING_UBL with its manual probing commands and see how well either of those works for you. Older MESH_BED_LEVELING is mainly included as an option in Marlin as the "least expensive" form of bed leveling for boards that can't contain the others.
