      I'm tuning my printer. Things are going okay but I get this stretched effect at the start of a layer. It's visible on the surface of a part. Additional walls may hide it I guess?

      Is this linked to acceleration settings, retraction & could pressure advance help?

      Thanks.

        yes that can be caused by retraction.

        it could be to much retraction. or the filament slipping.

        it could also be a wrong thermistor setting.

        post your config.g

            print a temperature tower to see if your thermistor settings is correct.

                None of them look great, hotter the better though it seems although I cannot be sure the actual temp correlates with the temp in DWC.

                FYI the PLA was only opened at the weekend although I've had it sat around for a while. On my other printer 215 is about the sweet spot for this PLA.

                  if your thermistor setting is incorrect then 215 will not be real 215
                  it can easily be off by 20-40c

                    The other printer is a stock Polaroid 250s so I am assuming it’s calibrated somewhat? That’s my comparison. Point taken though

                      Benchy using my current settings, sliced in Cura 4.8.

                      0.2layers. Printed at '235' which is too hot for PLA.

                        can you print this

                        https://www.thingiverse.com/thing:2080224

                        and try and calibrate your retraction with it.

                          I think 1.6mm retraction 50mm/s looks best.

                          stringing1.jpg

                          0, 0.5, 1 retraction

                          stringing2.jpg

                          1.5, 1.6, 1.75, 2

                          I think 1.5mm is close but has some slight surface blobs.

                          I previously had it set at 2.5mm.

                          Note: Pressure advance disabled in config.g for these prints.

                            ok see if that improves the benchy. nearly 1cm difference for retraction is a lot.
