    I paused a print and tried to resume it and the effector moved in a "U" shaped move when resuming the print. Due to this, the nozzle crashed into the printed part and messed up. This is on a delta printer.

    I am attaching config.g, pause.g and resume.g.

    Thanks,
    Balaji

          @balajiramani this may be resolved in 3.6.0-beta.2. Please test again using that version. You may find these files useful for testing, they describe circles at 2mm and at 50mm height above the bed.

          You may also wish to try the 3.6.0-beta.2+4 build at https://www.dropbox.com/scl/fo/ga0jqwfksechhukg2uiz8/AOV3DR8z1C0UWczc8Rx25gE?rlkey=4saeh9luddndvxbhb0kdaqugr&dl=0.

            @dc42 I uploaded the 3.6.0-beta2+4 build an changed the height from 50mm to 10mm to as it would be easier to see if the problem occurs. When pausing, the effector moves in a straight line, but when resuming, it moves in a 'U' shape. I am attaching a video that shows that.

                @balajiramani is your board a Duet 2? I think I've spotted the cause, but it only affects Duet 2 boards.

                [EDIT: from your config.g file I think it is.]
