Bed leveling method not working with Repetier firmware 0.92.9?

  • I homebuilt a delta 3D printer (like Kossel mini) with a Z probe near the hotend with manual deploy and RAMPS 1.4 board:

    • I configured the Repetier firmware with the online tool;

    • All my endstops (included the Z probe endstop) work in reverse mode, so I reversed the endstops triggering option;

    • I enabled Z-probing and set the BED_LEVELING_METHOD to 1 (n*n grid);

    • I set Z_PROBE_REPETITIONS to 3, and;

    • Finally I downloaded it and uploaded to my Mega 2560.

    Then I tested it inside Repetier-Host and all seems to work well (homing, moving, extruding) except for the Autobed leveling method.

    Specifically, it always starts measurement of 3 Points (with 3 probe repetition each) even if I change the type of measurement.
    It never does a grid measurement or a 2 points mirror measurement.

    I also tried to re-upload the firmware with EEPROM_MODE to 0 but didn't work.

    Does anyone have the same issue, or can explain to me why this happens?

    As a guess, you are using the wrong command. If set for n x n grid, you get 3 point measurement with G29, but that is not auto leveling, it is just setting Z height - based on average height at 3 points.

    What you need is G32 S2 with S2 to store result in EEPROM (and therefore you should have EEPROM enabled with auto leveling. It is also used to store endstop offsets).

    Ho thanks man! I thought it was the same as the Marlin firmware code. So the right procedure is: G29 then G32 and at the end G33 ? Please can tell me where can i find a reference to all codes in the Repetier firmware? thanks

    No, skip G29 completely, no need for that. G32 S2 is all you need. G33 makes sense only after you have calibrated parameters to best fit bed. The less it has to do the better or you get wavy surfaces higher where it is disabled. All gcodes can be found in Repetier.ino file with description. -> gcodes has also a good overview of most commands.
