      I've had a problem crop up lately and I'm at a loss to determine what it is. During X and Y moves, the machine randomly stutters briefly then starts moving again. The faster the speed, the more it pauses. Z axis doesn't do this and neither does E. The machine is a 400x400x400 Voron 2.4. It is running DWC 3.4.6. It's not a slicer issue as I've tried it in both Simplify3D and Orcaslicer. The odd thing is that it doesn't do it at all when I command a homeall and the head moves to home X and Y but will have a slight stutter when moving to probe Z (Bltouch)

      More bits of data, it doesn't do it at all until I run mesh compensation test.. During these "stutters" there is no perceptible voltage drop and the MCU is running between 36 and 40c. The stepper motors are cool to the touch.

      Stalling?

      Thoughts?

          Now that i think about it, I've been having some issues with printing height. It prints fine but in the center of the bed, it prints too low and the print peels up. This started happening about the same time as the stutter seemed to start. Could my height map file be corrupted or maybe the SD card?

            @SpeedyDad post your config. You probably have your jerk set too low on Z

              @jay_s_uk How would that affect it if it is only affecting X and Y. I have not changed Z jerk settings and this issue just started happening. Here it is anyways.

              config.g

                @SpeedyDad because you have a height map applied and it's therefore moving in Z too.
                M566 Z12 is way too low, especially for a v2.4. There's no reason it can't be the same as X and Y with it being belted. But if you don't want to go that high, make it at least 60, if not 120

                  @jay_s_uk OK, that makes sense. I'll give that a try.

                    @jay_s_uk Yup, that was it. Thanks! It's odd. I can't recall ever changing that but it is possible.
