Bed Leveling stops midway on leveling mesh



  • Hello Again,

    After solving the issues on triggering my piezo sensor, I got a new problem

    After 15-20th probing point, the machine stops and produces the following error

    G32
    Error: Z probe was not triggered during probing move

    The nozzle does not hit the bed though
    On that certain point, the reading was Z-4 on webcontrol.

    This is my config file

    ; Z-Probe
    M574 Z1 S2 ; Set endstops controlled by probe
    M558 P4 I1 R0.4 H4 F800 T2500 ; Set Z probe type to switch and the dive height + speeds
    G31 P400 X0 Y0 Z0 ; Set Z probe trigger value, offset and trigger height
    M557 X0:330 Y0:660 S40 ; Define mesh grid

    You may need to increase the dive height - it's the H parameter in the M558 command.



  • It seems that the job is done. Another solved problem!!!!

    ; Z-Probe
    M574 Z1 S2 ; Set endstops controlled by probe
    M558 P4 I1 R0.4 H15 F800 T2500 ; Set Z probe type to switch and the dive height + speeds
    G31 P400 X0 Y0 Z0 ; Set Z probe trigger value, offset and trigger height
    M557 X0:330 Y0:660 S40



  • Another Question. Do I need to include the G29 S1 command to auto-load the leveled bed prior printing or is it done automatically??
    I have saved the bed mesh and the file heightmap.csv appears on the system

    If you run G29 S0 or just G29, if the probing is successful then the height map is both saved and activated. So no need to use G29 S1 as well, unless you do something that cancels bed compensation meanwhile.



  • @dc42 said in Bed Leveling stops midway on leveling mesh:

    unless you do something that cancels bed compensation meanwhile.

    Like power cycling the printer. At some point the mesh needs to be loaded after a startup. You can load it in config.g to apply all the time or in your slicer start code to apply just before a print.

    On my SCARA printer I use G29 S1 at the end of the homeall.g file.
