Question about M558 and G31



  • Hi,

    Both M558 and G31 are related to Z-probe configuration.

    I always have them together in my config.g files.

    Yet since there are two commands I'm thinking that there are times when they should be used alone. Yes? No?

    Without fully understanding why there are two it would seem that one command would suffice.

    Any info to aid my understanding would be greatly appreciated.

    Thanks.

    Frederick



  • I use a G31 in a couple of macros to set the z offset. Since PLA and PETG like different amounts due to temperature of the hotend. I then call the macro needed in the slic3r startup gcode. I do leave a G31 in the config file as a default.

    Thanks much.

    I don't a permanently mounted z-probe so I would never have thought of that application.
