        M566 X900.00 Y900.00 Z22.00 E120.00:120.00 ; set maximum instantaneous speed changes (mm/min)
        M203 X6000.00 Y6000.00 Z280.00 E1200.00:1200.00 ; set maximum speeds (mm/min)

        These are the lines you would edit by the way.

        Also, what slicer are you using? Could you share a video of the behaviour?

          Are you printing the file from the built-in SD card, or some other way (e.g. via USB or an external SD card)?

            I am printing the file via the Duet Web Control 2.0.4

            The slicer is Simplify3D.

            When the head stops it leaves small blobs of filament.

              I increased the speed. without success. Still stopping. What am I missing guys?

                @Rattlemycage Does this momentary stopping coincide with a layer change, or with a retraction, or is it seemingly random? Can you make and post a video of it happening?

                  @Rattlemycage, It is seemly random. On a single layer of an object perimeter, say 4 inches by 5, it might actually come to a stop 7 or more times. I tried to upload a video but my files are larger than the 4mb permitted.

                    For larger files you will need to host them on a file sharing cloud platform like dropbox or google drive or vimeo or youtube.

                    Can you also share the sliced gcode file itself?

                    Your E speeds are still quite slow at 1200mm/min. That would restrict your retraction speed to 20mm/s. If you have a longer retraction move that can lead to a noticeable pause at travels and layer changes.

                    A low E jerk can also cause slow downs when used with pressure advance, but I don't see pressure advance command in your config.

                    I would suggest trying these speeds

                    M566 X900 Y900 Z200 E3000:3000 ; set maximum instantaneous speed changes (mm/min)
                    M203 X6000 Y6000 Z2000 E6000:6000 ; set maximum speeds (mm/min)
                    M201 X2000 Y2000 Z250 E3000:3000 ; set accelerations (mm/s^2)
                    M204 P500 T2000 ; print and travel move acceleration
                    

                    I've removed the .00 to make it more legible. And added the M204 command to have seperate print and travel move accelerations which should speed up travel moves quite a bit which can help blobbing as well. (assuming the blobbing is on retractions.)

                      Thank you for all your assistance. I feel rather embarrassed to ask for more.
                      I have the settings for my machine.

                      Printing Acceleration 1000.00 mm/s2
                      Retract Acceleration 3000.00 mm/s2
                      Travel Acceleration 1000.00 mm/s2
                      Max Acceleration X 9000.00 mm/s2
                      Max Acceleration Y 9000.00 mm/s2
                      Max Acceleration Z 100.00 mm/s2
                      Max Acceleration E 10000.00 mm/s2
                      Max Jerk X/Y 12.00 mm/s
                      Max Jerk Z 0.40 mm/s
                      Max jerk E 5.00 mm/s

                      How do i put these values in my config.g please?

                      Thank you

                        Well you must first edit the config.g file either on the web interface or on the SD card directly.

                        https://duet3d.dozuki.com/Wiki/Duet_Web_Control_Manual

                        The values you want to edit are the ones I pasted above. Bear in mind that the values you posted are from marlin and are in mm/s and RRF uses mm/min, so note the units being used.

                        I would still recommend the values I posted.

                        M566 X900 Y900 Z200 E3000:3000 ; set maximum instantaneous speed changes (mm/min)
                        M203 X6000 Y6000 Z2000 E6000:6000 ; set maximum speeds (mm/min)
                        M201 X2000 Y2000 Z250 E3000:3000 ; set accelerations (mm/s^2)
                        M204 P500 T2000 ; print and travel move acceleration
