      can someone please help me with this?

      My prusa i3 with duet wifi 1.19beta firmware stops for a second and resumes printing when it should be a continuous print,

      video to see what is happening.

      thanks in advance.

      best regards

        When it stops, does the extruder motor retracts a lot?
        I am guessing it's due to relative/absolute extruder mode

                Can you provide a gcode file up to part of the first layer? and also your config.g

                    Yes, please share the gcode file.

                            The problem is that you have set your maximum extruder speed to 100mm/min in the M203 command. That is very low and it is making retractions very slow. A more typical value would be 3000 to 6000 mm/min.

                                  I had mine set at 1300 and was getting under extrudes at speed. Didn't even know i had this issues till i checked. Thanks dc42, you got a 2 for 1 on this solution 🙂

                                    3 for 1. 1200 here. Getting bumped up.

                                    Edit: Huge difference. I have been fighting layer issues and this was the fix. Looked up what the stock printer board was set to (9000) and changed it to that.
