      Morning all.

      Just wrote a python script to output a cylinder spiral with stepped speed changes to check for resonances on my machine.

      I'm thinking about recording a noise profile on the phone while printing and adding M300 to clearly identify speed changes on the plot. Will this cause a motion stutter?

      If not known for sure I will try anyway!

      Thanks.

        Doesn't appear to cause an issue.

            M300 should not cause a stutter.

              Pressure advance changes do though.

                Yes they do, though I don't know if that was always the case.

                  @Phaedrux yeah complete stop along with a little bump on the vase test. In my case it saves me getting the rule out to count through the changes on a more subtle test.

                  Not what I expected when I've heard look ahead mentioned. Not my biggest issue right now though. My 2A salvaged motors at 1.35A predictably aren't working great. 1.68A motors on order.
