          Make sure
          M98 P"0:/sys/setDefaultProbePoints.g"
          Comes after your G31 in your BlTouch section

              @owend that did the trick but now i need to turn down the amount of probe points
              var MinSpace = 10 ; put default minimum spacing
              var MaxSpace = 30 ; put default maximum spacing
              var ProbeNumX = 8 ; put default probe points
              var ProbeNumY = 8 ; put default probe points.
              var ProbeCenterX = 285 ; will be updated to probe centre of print
              var ProbeCenterY = 270 ; will be updated to probe centre of print

              with my 100x100mm print its trying to do a 13x13 grid what do i tweak to lower that?

                @owend ok after letting it 100% there were more errors

                8/14/2022, 10:15:03 PM Error: M557: bad grid definition: Spacing too small
                8/14/2022, 10:14:19 PM Error: in GCode file line 773: G1: expected '}'

                line 773 is your
                G01 X0 Y{move.axes{1}.max} Z0.6 F1500 ; Move to back corner while heating

                  Change your minSpace and maxSpace in the macro to reduce number of probe points
                  Try 50 & 100

                  The G1 is my bad
                  I did a search and replace when I was changing the braces, but changed one that should remain a square bracket

                  Change this line in superslicer
                  G01 X0 Y{"{move.axes{1}.max}"} Z0.6 F1500 ; Move to back corner while heating
                  To
                  G01 X0 Y{"{move.axes[1].max}"} Z0.6 F1500 ; Move to back corner while heating

                  Or delete the line if you don't want to move there while heating

                    One down one to go I’m still getting the m557 error with the 50/100 spacing will this be normal a normal error from down sizing the bed mesh or is there a fix

                    Error: M557: bad grid definition: Spacing too small

                    ——-Error: in GCode file line 773: G1: expected '}'———- is now fixed

                      @ratrig0331 the most probe points you can have on a duet 2 are 121 and on a duet 3 are 441

                        @jay_s_uk too many points isn’t the issue I think, it must be too few points? With the settings first told to me it wanted to do a 13x12 grid on a 100mmx100mm print 156 points total, than I changed the min max to 50/100 and it only probed the middle and 4 conners and gave the same error

                          I believe the problem you are having is that I didn't allow for a probe that was offset to the other side of the extruder to mine.

                          Try these files.
                          I think it should sort it out.

                            @ratrig0331 the minimum spacing between points allowed is 0.1mm in each of X and Y. "Spacing too small" means you have tried to specify a smaller spacing than that.

                              @dc42 said in Only probe where the part will be printed:

                              the minimum spacing between points allowed is 0.1mm in each of X and Y. "Spacing too small" means you have tried to specify a smaller spacing than that.

                              In that case I'm at a bit of a loss how @RatRig0331 is getting that error using my code.
                              It's early morning here (Australia) and I have to go to work, so I can't look at till I get home.
                              @RatRig0331 Can you please un-comment all the lines in the mesh.g that show the calculations and post the output from the console.

                              At the start I work out the maximum possible number of probes if a full bed was done using maxSpace.
                              Later I use the object size to recalculate the number of probes also using maxSpacing.
                              The lesser of these two numbers is used (or should be).

                              There must be a fundamental flaw in my logic (at least with your bed size and probe configuration). 😕

                              It also occurs to me that I haven't catered for deltas or printers where X0, Y0 is in the center of the bed.

                                    The M557 that is causing the error seems to be well after all the stuff I did.
                                    Check for an M557 somewhere else in your slicer start gcode

                                        sorry one more question so far every time the start code hits your lines the hotend and bed turn off during the mesh than back on after. i tryed moving some things around but it still turns off all heaters during the mesh. here is my full start code

                                        BED_TEMP=[first_layer_bed_temperature]
                                        G90 ; use absolute coordinates
                                        M83 ; extruder relative mode
                                        M140 S[first_layer_bed_temperature] ; set final bed temp
                                        M104 S150 ; set temporary nozzle temp to prevent oozing during homing and auto bed leveling
                                        G4 S10 ; allow partial nozzle warmup
                                        G28 ; home all axis
                                        G1 Z50 F240

                                          The turning off of the heaters is deliberate and is done in mesh.g
                                          I find that the accuracy of my bltouch suffers if they are on when probing
                                          I run a 240v bed.
                                          I'll have a look later and add an option to not turn off heaters.

                                            @owend you can turn off heaters temporarily during probing by using the B1 parameter in your M558 command.
