BLTouch reliability testing, is this good or bad?



  • So I ran this macro I got off somebody on the forum to probe 10 times and I am using a mirror bed surface. and this is the results I got, seems pretty far off or is this an ok range? It is a geniune bltouch only a month old

    M292
    G32 bed probe heights: -0.025 -0.015 -0.013 -0.025 -0.023 -0.030 -0.043 -0.058 -0.050 -0.043, mean -0.032, deviation from mean 0.014



  • try decreasing the dive speed by decreasing the F parameter of the M558 in your config and see if that improves the result.

    this is my result with a custom probe.
    G32 bed probe heights: 0.036 0.043 0.041 0.049 0.044 0.039 0.045 0.044 0.044 0.040, mean 0.042, deviation from mean 0.003



  • wow, thanks. I cut both the F and the T parameters in half and this is the results I got. Way better

    M292
    G32 bed probe heights: -0.028 -0.028 -0.030 -0.033 -0.033 -0.035 -0.035 -0.035 -0.038 -0.043, mean -0.034, deviation from mean 0.004
