Taz 6 bed leveling question



  • Hi,

    I'm thinking about converting my Taz 6 to a Duet Maestro board and overall it seems pretty straightforward except for the bed probing.

    The taz 6 has a fixed bed with no option to manually level the bed and has 4 metal washers that are approximately 10mm outside of the printable area on the left and right edges. Probing is based on an electrical connection forming between the nozzle and the washers.

    Ideally I would love to use true bed leveling to level the x gantry (it has 2 motors and I only use 1 extruder so I can map the second extruder to z). But since I cannot manually level the bed, I would need to do mesh bed leveling of those 4 points as well to deal with the fact that the bed isn't perfectly leveled.

    Is it reasonable to first perform a G32 of the 4 points which to get "approximately true bed leveling" followed immediately by a G29 which probes those same 4 points to do bed compensation after the leveling? If so, how does one specify the points? Can I define a grid with the 4 extremes and the appropriate spacing between points?

    Thanks!
    Chris



  • Maybe easier to add a seperate probe like a BLTouch?

    Yes you can do that. For G32 you specify the coordinates of the 4 points in the G30 commands in bed.g. For G29 you specify the min, max and either X and Y spacing or numbers of X and Y points using M557.
