2.03RC5 leveling issue



  • Since I installed 2.03RC5 builds after 2.02 I have an issue with leveling.
    Everytime i do a bed level it gives me a different height.
    -home, g32, m500
    Everytime a different height H*** (454, 461, 475, 480)
    Already calibrated the Z probe trigger height.

    2.03RC releases are no longer supported, because 2.03 has been released.



  • there were some changes to leveling since the rc. please update to 2.03 release and try again.

    also why 0.1?
    M208 Z0.1 S1 ; Set minimum Z



  • @dc42 ok, I'll try



  • @veti coz I print with 0.1 layer step
    If I set 0.2, first layer (with 0.1 layer step) very poor and don't catch on bed....



  • no you adjust the offset of your probe in the M558 command not with M208



  • Still not work!

    I suspect you are getting inconsistent results from probing. Try replacing S7 on your final G30 command by S-1 so that it prints the errors without making corrections. Then run G32 several times and see how consistent the results are.

    Also, we don't normally advise using 7-factor calibration unless the height map is a particular shape. 6-factor usually gives better results.

    Those results show differences of around 0.02mm which isn't ideal, but not too bad. Try S6 instead of S7.



  • @dc42
    Did s6.
    Now G32 repeats little good....

    But before on 2.02 was be after 0.03-0.08(maybe because I did matte on my glass today)

    Thank you. I will try to print something tomorrow....



  • @dc42
    Now better, but not ideal (((

    Why this happening?
    First layer poor....some place the nozzle touching the bed some plase have pit...
    If I run G29 the nozzle starting print like on wave... and first layer much more poor .


  • administrators

    @spax, what type of Z probe do you have on your delta printer?

    After run G32 a few times, if you then run G29, what does the height map look like?



  • @dc42, I use your IR probe.

  • I have 6mm aluminium plate + 0.5 heatsink pad + 4mm glass (back side painted in black).



  • @dc42 any thoughts?



  • Can you rerun the G29 heightmap with a piece of plain paper covering the bed surface? The idea being to eliminate any inconsistencies in the IR probe reading the surface.


  • administrators

    Also please post a screen shot with the height map rotated so that we are looking along the X axis.

    That height map looks terrible, as if you are probing off the edge of the bed or something like that.
