      It looks like under extrusion. Have you calibrated the e steps yet?

      What settings are you actually printing at?

        Hi there,

        See below for config.g details:

        I'm using the new nozel X which is supposed to be polyphobic...it seems as clean as a whistle when I extrude, its a 0.6mm nozel.

        I am using an e3d set-up: Volcano with Bowden titan extruder.

          When you changed to a 0.6 nozzle did you also update the slicer settings to use a 0.6 extrusion width?

          And as I asked above, did you calibrate your E steps?

            Yes to slicer, that was a simple one, Esteps? Do you mean steps per mm?

            Best,

              @tef9 yes. If you were using a different sized nozzle before switching to the 0.6 nozzle x the steps per mm for the extruder may be different. You may also need to adjust the filament flow factor in the slicer.

              That could account for the under exteruded look of the parts.

                What is the extruder? 1500mm/min max speed and 1500mm/sec2 acceleration seems low for a 1.5A stepper?

                Judging by 419 steps per mm on the extrusion axis this is a geared extruder. Should be capable of higher speed and accelerations or these values will restrict the effectiveness of the retractions.

                As others say though, it appears under extruded and occasional PID tunes are worth while. I will now go read up on autotuning as I tend to do it with filament in the hotend!

                Edit: Just seen standard shipment for the Tevo LM is an E3D Titan. dc42 runs with them so may be able to pull acceleration and jerk settings from his recommendations in posts on this forum.

                  I've not used a delta but those acceleration settings seem conservative on the other axis too.

                    Hello,

                    Thank you for all the replys - so far I have :

                    1. Updated the values for acceleration etc..

                    2. Tuned the H1 heater and added the M307 to the config.g

                    3. Worked out the steps per and changed it as required in the config.g

                    By printing the same part there is a greater density, also the filament is not...shiny when printed? The print on the right is the new print, the print on the left is the same as yesterday.

                    Could this be temperature or retraction?

                      A 0.6 volcano is going to drool quite a bit, but it looks quite extreme in the photo. Is retraction even turned on in the slicer? Are you using combing? What slicer are you using?

                        Hi,

                        I am using Slic3r, I did have retraction set there but it seemed to make more mischief than expected. Should it be set in both firmware and slicer? I can up the firmware setting and try that.

                            I used a .6 volcano exclusively for a couple months and probably 15 lbs of filament.

                            I found fast retractions work better around 70mm/s, I really didn't have much of a dribbling issue- this was on a stupid ramps board too.

                            I also never used combing and still don't, I just retract on layer change.

                              I'm still stumped and get lines across the part...does the firmware retraction not work?

                                For firmware retraction to work it has to be enabled in the slicer. It varies between the slicers on how to do this.

                                  Opps, did not know that, thought it "just did it" when retracting.
                                  So now things are looking better 🙂

                                  Edit, does the firmware limit the retraction? If you have firmware set to 4mm is that the most you can retract?

                                    You can configure retraction completely with the M207 command

                                    You might find this helpful for tuning, especially if you have a PanelDue.
