    Hi guys!

    Finally I've finished my upgrade from Chitu board to Duet3d Wifi, plus changed pulleys from 17T to 16T, changed lead screw (8mm travel) to regular screw(2mm travel), X axis has got 0.9deg stepper(planning to change Y axis stepper a bit later as it has integrated shaft ~300mm length) and one more major upgrade was installing E3D filament tube(heat break?) + E3D heat block + E3D nozzles(one is all metal and one is with Capricorn PTFE tube) into MK10 cooling block + MK10 extruders/carriage 🙂 Later planing to change extruder pulleys, add gear and install 0.9deg steppers.

    Wow! It is soooo quiet now! But have some kind of vibration noise from X axis at some speeds... need to find out..

    So today I have made the first print with Simplify3D old settings at 50mm/s , PETG, printing temp 230C, heated bed 70C, print fan is off(have a problem with it...) (except changed retract distance from 1.6 to 0.8 and switched off coasting and wiping). I have made just an initial setup of Duet3D and tuned up PID settings, set exact(measured at 1mm/s) steps for extruders.

    I need your opinion about quality of that print(25mm cube) and what do I need to do next to improve printer quality please! And maybe some insights about acceleration/jerk settings..

    My worst nightmare was to see Z-banding 🙂 And I don't see it at all!! )
    Problems that I see and how I could :

    • retraction on layer change
    • pressure advance

    So what are my next steps ? non-linear extrusion and after that pressure advance? Or something before that is needed?

        I suggest you try reducing the extrusion factor a little and enabling pressure advance.

          So I need to lower extrusion factor by M221?

          Right now I am calibrating non-linear extrusion and getting strange results on my MK10 extruder:
          changed steps/mm to 98
          so 1mm/s = 100mm of filament
          2mm/s = 95.46
          3mm/s = 91.69
          4mm/s = 89.55
          5mm/s = 54 ...
          6mm/s = 44.4...

          But at 5 and 6 I don't hear skipping steps, but seems that I am skipping them.
          So I've calculated A and B by 1 to 4 range and getting: A = 0.066859877 B = -0.004560378

          Is it ok to have B as negative?

            It would be unusual for B to be negative, but as your B coefficient is so small anyway, you could use a straight line fit instead (B=0).

              Remeasured:
              1mm/s = 100
              2mm/s = 98
              3mm/s = 95
              4mm/s = 90

              and recalculated : M592 D0 A0.000185 B0.00688
              Strange again...
              1mm/s = 100
              2mm/s = 98
              3mm/s = 108

              Very bad extruder gears?

                So not very consistent.

                  @briskspirit hey what style of printer are you using this for? I am trying to configure my Printrbot Simple Metal and you don't have a G31 for the Z offset. That is the part I am struggling with.

                      @dc42 So I have calibrated pressure advance and got M572 D0 S0.242 , M221 didn't touched yet, non-linear didn't touched either.

                      Print speed 50mm/s, outline 60%, solid infill 80%, retraction 1mm/s, retraction speed 60mm/s. Layer height 0.2mm, nozzle 0.4mm, extrusion multiplier 100%

                      Everything is almost ideal except transition seam between start and end points and too much rounded corners(2 black lines on the third photo on the left are shadows from a ringing):

                        So I decided to check what is wrong... have changed acceleration and max speeds to those calculated and altered jerk values a bit. Have no excessive noise or step skipping. Re-calibrated pressure advance and got these results:

                        M572 D0 S0.120

                        print speeds: default 80mm/s, outline 65%, solid infill 65%, movement 150mm/s

                        And have got very good results with seam(almost not visible), very good quality top infill. But got rippling on both X & Y axis (1mm period) and one very rounded corner(on photo).

                          At 40% of 80mm/s for outlines I am getting less period and less amplitude. (Seems like ~0.8mm)

                          Edit:
                          Played with :
                          M204 P400
                          M204 P384
                          M204 P340
                          M204 P192

                          Period is changing, but not amplitude... same. But have got nice seam at M204 P192 (can't see it at all!) and rounded corner became less rounded.

                            It looks like you got quite bad ringing because the amplitude is dying down very slowly. Check the tightness of the belt that controls the axis perpendicular to the face that exhibits the riging.

                            You could try the dynamic acceleration adjustment feature in firmware 2.02RC6, see https://duet3d.dozuki.com/Wiki/Gcode#Section_M593_Configure_Dynamic_Acceleration_Adjustment.

                              @dc42 Both axis are with tight belts for sure, new pulleys and etc... And I don't hear any resonance or other audible problems. Both axis has almost the same ringing problem so I am lost with that problem... Something is flexing too much? Maybe could be the plastic carriage on LM8SUU bearings? I just can't understand what can be so wrong even at 30mm/s to give such a big ringing on both axis..

                              Or could it be because my belts might be overtightened ? (Sounds like a guitar strings)

                                      Or could it be because my belts might be overtightened ? (Sounds like a guitar strings)

                                      I don't know if being too tight causes ringing per se... but it does cause all kinds of other bad things.

                                      "Tight, but not too tight." Yeah, what a load of... anyway... "Guitar string" is definitely too tight. IMNSHO.

                                        Which motors, exactly? Are you using 12V or 24V power? Your Y axis motor in particular almost certainly needs 24V power, and even then the maximum speed before it loses torque and becomes noisy is likely to be quite low.
