        because Z probe cannot reach it

        It didn't fail. It's just telling you that your mesh size has areas that aren't physically reachable by the probe. If you want to get rid of the errors, modify your M557 mesh xy positions to take the probe offset into account.

          @Phaedrux seem odd, as I have never seen that in the past and the following is well within the build plate of 200x250

          How can the probe not reach them. Can this be a connection issue or mechanical adjustment in the probe?
          Going to run these again today with a cold bed will post results if different.
          Thanks,

            @airscapes your probe offset in Y is -21
            to probe at Y239, the nozzle needs to be Y260, which is outside your axis limits

              @fcwilt Thanks, I will look up what I am changing as I do not recall what those do since it was set up over a year ago

                @jay_s_uk Thanks, Yes, I just positioned the machine to one of those points and I now I get it! 🙂 I will update my macros to only include what the probe can reach, or at least make a note to myself to ignore those next time..

                  This probe has been in place for a year I have made other maps and tend to reuse them. This has happened with the failure before complete one other time.

                  M558 P9 C"^zprobe.in" H3 F100 T6000 A3 R1.25 S0.01 B0.
                  G31 X0 Y-21 Z1.57 P25 ;

                  In M558:

                  Change the S0.01 to S0.03

                  Change the R1.25 to R0

                  In G31:

                  Change the P25 to P500

                  Let us know if those changes help.

                  Frederick

                  Can you explain the P25 to P500? I probably found P25 for BLTouch in this forum or in an example. What is it actually doing, the dictionary just says trigger value and does not elaborate?
                  Here is one such post

                  You really only need to care about the P value when using an analog probe. Just set it as P25 for the BLtouch.

                    When triggered my BLTouch probes read 1000. When not triggered they read 0. The setting of P500 is midway between 0 and 1000.

                    It has always worked for me.

                      Interesting, still reads 1000 and 0.. not but not every time it reads a point. I did run a full bed at 100C with no failure to read. Running 110C now. Thanks!

                        The trigger time on a BLtouch is very short and then resets. The DWC display might not always refresh at the right time to catch it.
