    Is there an optimal sequence for machine tuning?

      There are a lot of virtual knobs to turn when getting a machine dialed in. Is there consensus or an expert opinion on what to tackle first? There are so many interactions between speed, accel, jerk, PA, DA, X, Y. Z, & E. Also, when starting to adjust the first variable, how do you have the others set?

      I'm not having any significant issues, but it seems there could be an endless cycle of test prints and tweaks as one sorts out the interactions. I just feel like I'm probably not taking the most efficient approach.

      Opinions/Advice/Links to existing threads? TIA

        That's my take on it. There are a lot of knobs to twiddle, so I think it helps to establish some hard limits first and work back from there. Key being your hot end melt rate, since you can't exceed that and still print successfully. From there your desired layer height and extrusion width will give you the optimum print speed. From there jerk and acceleration are much easier to tune.

        These macros may help in your tuning.

          Thank you. I'll give that sequence a go - although upgrading my second printer to a Duet may take priority.
