      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?

      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

              Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

                only with delta calibration and mesh compensation

                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.

                              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.

                                    Try to halve the speed values to 3000

                                        could this have something to do with that t2 tool? the printer is set up so that 0 is the effector, or rather the fisheye center

                                          You mean this?

                                          Why does it go from P0 to P2 then P5, but P5 still uses G10 commands with P2?
