Doubts about mesh bed compensation (taper height) [SOLVED]



  • Hello,

    I would like to use mesh compensation. I thought I was already using it but it seems I was not 😄

    At: https://duet3d.dozuki.com/Wiki/Using_mesh_bed_compensation

    It says:

    Running G32 to auto calibrate a delta printer will clear the local height map info (but not the copy in heightmap.csv). Therefore, if you wish to use both auto calibration and mesh bed compensation, you must run G32 before you run G29, not after. You can include a G29 command at the end of your bed.g file if you wish.

    So if I use G32 at my start script I could put "G29 S1" at the end of the bed.g file so it always load the mesh after the bed compensation, right?

    Another doubt is about the M376 command. At https://duet3d.dozuki.com/Wiki/Gcode#Section_M376_Set_bed_compensation_taper it mentions that:

    Therefore it is recommended that the taper height be set to at least 20x the maximum error in the height map, so that the maximum amount of the resulting over- or under- extrusion is limited to 5%.

    About what error it refers too???? Maximum deviations, Mean error or RMS error????

    Thank you very much!

    Yes.

    Maximum deviation.
