      Hi,

      Where in config.g should the M375 command be placed?

      Thanks.

        M375 is provided only for compatibility with other firmwares. Normally you would use G29 S1 instead. A common place to put it is at/near the end of homez.g and homeall.g files.

          Good to know.

            There was a typo in my previous reply, I omitted the "end of". Now corrected.

              @dc42 Is it also acceptable to load the heightmap in config.g? Or should it only be loaded after homing Z?

                With some firmware versions there was a problem if you homed Z using a Z probe when a height map was already loaded. So when using older firmware, you should not load a height map in config.g. In firmware 2.01 and later, it should be OK to.

                Please note, when running delta auto calibration or Z leadscrew levelling, there should be a M561 or G29 S2 command in bed.g to clear the height map first. So you may also want to load a height map at the end of the bed.g file.
