    Run the macro then delta calibrate then G29 sorry Dopy moment here

        Ok. Done the macro again,
        G32
        Calibrated 6 factors using 16 points, (mean, deviation) before (1.067, 0.643) after (0.000, 0.063)
        G29:

            @Lakeman This is a good page for visualising the effects of the delta (M665) parameters: http://boim.com/DeltaUtil/CalDoc/Calibration.html
            I'd guess your delta radius is wrong. Set up and run autocalibration. See https://duet3d.dozuki.com/Wiki/Calibrating_a_delta_printer

            Edit: never mind, you got there!

              I entered the values of the delta calibration in the config file, ran the macro and G29:

                that looks better notice your radius is some 8mm bigger
                I would think about resetting your sensitivity back to default also
                M672 S131:131 up to you but I've never seen any benefit to adjusting it with the stock bed
                or of a config-override on a delta when you do a calibration before a print
                Try a print ? fingers crossed ?

                  I tried printing after this, no succes...
                  I will set the sensetivity back and try again

                      Failed again. The weird thing for me is that is is to close at one point, and to high 5mm further. It is so local that calibrition can hardly be a problem. Maybe I should go with an even finer mesh setting, but the original predator did not have a super fine mesh and had no problems at all....

                        Long shot...
                        Can you measure the carriage spacing and then effector spacing of the ball joints

                        or unclip the effector and line it up it to the carriage on all towers ?

                          If they are fine
                          Heat bed to 60c 130c hotend home then calibrate Z0.1 see if it goes to that position after calibration.

                              Measured the spacing on the carriages and on the effector: Effector 64.6mm carriges 64.1mm
                              So there is room for improvement..

                                @Lakeman On my delta, I've always had issues with mesh calibration. I only use it to check the bed level, then turn it off for printing. When you're doing the delta calibration, is it turned off? Check there's an M561 and G29 S2 at the beginning of bed.g (assuming that's where you delta calibration is), then if you do a mesh calibration afterwards, cancel it before trying to print.

                                  Did you change your belts? or tighten them as adjuster is touching the pulley plate so no more adjustment available mine have 15mm ish between them

                                    It seems to be making the same mistake with or without mesh, I just tried a very fine mesh and without after with no succes
                                    But maybe I have to fix the 0.5 mm in the spacing...

                                      would be good to rule it out .5mm when your talking 0.12 -0.3mm layers?

                                        I think ruling it out is the best plan, just not entirely sure if it will work if I just scale the printed parts a bit and hopefully end up exactly 0.5mm wider 😛

                                          I am printing a 0.2mm first layer by the way and I do not know how much effect spacing between the balls has on the height,
