      Thanks. I'm afraid that's the extent of my delta knowledge and I know even less about the LPC port.

      A video may help and the results of M122 never hurt.

      Is RC2 the latest for the LPC port, or can you update to 3.2 final?

            From your video is seems like it's triggering the probe, but then skipping steps on one arm when it tries to return to the dive height causing it to lurch.

            Are you sure there's no slipping grub screw or something like that?

                There should be no differences between the LPC port and the normal version in terms of kinematics etc that I'm aware of. There are some other restrictions but that's mainly due to memory.

                  You can upgrade to 3.2 final from here https://github.com/gloomyandy/RepRapFirmware/releases/tag/v3.2_1

                    it happens only with delta calibration and mesh compensation, with normal use it is not observed

                        M350 X64 Y64 Z64 E64 ; configure microstepping with interpolation M92 X1761.5 Y1761.5 Z1761.5 E1488.59 ; set steps per mm

                        Pardon my ignorance on the LPC port, but perhaps you can try using x16 microstepping to get a baseline?

                        I notice in your M122 there are a lot of hiccups which can mean skipped steps, so reducing the microstepping could help

                          The printer behaves the same way only with delta calibration and mesh compensation, no problems with printing and moving, I do not think the problem is microstepping but I can try

                            @Orang_ yea, I really wouldn't run anything higher than x16 on an LPC

                              Yes, and it's the quick movements to raise Z after probing that it's skipping, and those moves would be generating the most step pulses. The hiccups are indicating an issue caused by too high microstepping values.

                              If this isn't the problem I'll be surprised.

                                  Are you still getting hiccups in M122 after a fresh reboot and running G32?

                                  You can add some commands to bed.g to lower the acceleration, jerk, and max speed before the probing and then return it to normal again at the end.

                                          it seems to be a problem with the firmware in particular rotary delta kinematics

                                            That won't have any effect on the G30 moves. You'll need to do something like this.

                                            That's much better

                                            Also, is your motor current set appropriately for your motors? 60-85% of rated max is the rule of thumb.
