    The y slope has returned for me using 3.5.rc3+4(from 13th March).
    similar to before, with about 1mm overhang on a 20mm high cuboid, sloping in the +y direction. X facing sides are vertical. Similar with filled or unfilled cuboid(I used 30x20x20 xyz). Running a kossel style delta with duet2wifi standalone.

      Adding to this, I too am seeing layer shifts with the 3.5.0-rc3+4-mms firmware. In some cases, the problem occurs on the 1st layer itself and the nozzle digs into the bed. Here is a photo that shows it.

        @balajiramani Is your printer a delta? If not I doubt if your problem is the same as this one. You may be better off starting a new thread to discuss your issue.

          @gloomyandy Yes, it is a delta.

            @balajiramani Can you post a picture or link of what the print that you had fail (in the photo above) is supposed to look like? I'm trying to work out what happened. Unfortunately I know very little about deltas, but it might be worth you posting your config.g file so that we can take a look at your settings.

              @gloomyandy Here is the first layer of the same gcode printer using 3.4.6.

              With 3.5.0-rc, the nozzle digs into the bed.

                @balajiramani Here is another photo that shows the slope in the y direction.

                PXL_20240313_153345638.jpg

                The one on the left was printed with 3.5.0-rc and the one on the right was printed with 3.4.6.

                    @balajiramani please run M122 before you start the print, then post a M122 report taken after layer shifts have occurred. I am interested in whether it shows any step errors. Note, after reporting the step error count the count gets cleared to zero, so if you run M122 again the information will be lost.

                      @dc42 I am getting a smooth y slope with no hics or step errors printing a 30x20x20 cuboid (filled)

                            @Adrian52 please provide those two GCode files you are printing that exhibit the problem.

                              @dc42This is the gcode - it gives the slope with IS on (I used zvd) and no slope with IS "none".

                                @Adrian52 thanks. My delta also has 200 steps/mm so I'll try it on that.

                                  @Adrian52 I increased the max speeds and acceleration on my delta to the values in your config.g and set the input shaping to be the same. The print came out OK.

                                  If you send me the GCode file for the other print that had a lean, I'll try that one.

                                  PS - I've just noticed an anomaly in the 'min interval' value in your M122 report after the print that leaned. That may be relevant to this issue. I will investigate it.

                                    @dc42 I only used that gcode file - for me, it leans with IS on, but is vertical with IS off. The effect is not that obvious - just less than 1mm over the 20mm height.

                                        @dc42 here is a picture of the effect:
                                        alt text

                                        the left cuboid is sloped in the y+ direction (IS on), the right cuboid is vertical. The short sides (x-facing) of the centre cuboid are vertical . The print quality seems fine to me, apart from the lean.

                                          @dc42 Here it is
                                          jig1_225.gcode
                                          I couldn't find the original gcode, so I resliced with the same conditions as the cube. I checked print, and amazingly it came out looking exactly like the blue ones in the early post, going vertical from the U cutout on the y+ face
