Mesh bed leveling on print area only

GekoPrime · March 29, 2023, 5:40pm

I usually skip mesh bed leveling because it takes too long

What if the bed leveling mesh could be limited to the print area? This is already implemented in mainsail and on the prusa mk4

As long as you do not turn off your printer, a bed leveling usually does not need to be repeated every print as it is stored in the printer and used for the next print.

Is that true if you remove the build plate between prints. I’ve been workin on the assumption that if I remove the place (say to clean it or to snap off a print) then I re-level but if I take the prior print off without removing the plate then I don’t bother. Is that a reasonable strategy?

I have a 1A-mini and it only probes where it prints !! I think it must be in the start g-code
