      Hello

      i have bed size 315 x430 mm with 8mm aluminium,
      and i have i still get this height map!

      What you guys think, maybe is too big space between 3 point for auto bed leveling with 3 independent z motor.

        Hi,

        What kind of aluminum is it?

          @matej1006 my guess would be a sagging gantry

          Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

                    Do you use a magnetic bed?
                    I have the same problems with a 355x355 bed.

                        tyr the mapping cold and compare with a hot mapping. I think the differences are a problem of the magnethight

                              @cando415 if you have a straight edge you will be able to confirm quickly that its not the bed that is that warped. I think @jay_s_uk was right with the gantry.

                                @t3p3tony yeah i will just unscrew a little all screw in linear rail and then try.
                                Maybe i have ma linear rails in back more closer than in the front of printer.
                                i hope is that 😉
