      @thedragonlord here's test file 4. For this one you need to configure firmware retraction using M207.

          I'll try this too. I've never used the M207, I suppose I have to configure it with the same params I set in the slicer for retraction, right? I usually set 3mm at 40mm/sec so I have to set:

          M207 P0 S3 F2400
          

          and set it in the config.g correct?

                PS all these files use relative extrusion. I will add M83 commands to the final versions, in the mean time feel free to ad M83 commands yourself if you do not have M83 in config.g.

                  @alankilian thanks, so far they look good (I'm looking at the measured sensitivity min/max). More test files to follow.

                          I can certainly run those files tomorrow.

                          Additional datapoint:
                          I ran an 8hr job yesterday with PETG (have had far fewer problems with PETG than PLA)
                          with zero issues after running with the the sensor set wide open:

                          M591 P3 C"e0_stop" S1 D0 L26.5 R1:200

                          printing at 60mm/sec perimeter and 80mm/sec infill.

                          If I slow down the print speed (only tried to slow to 40/60) I get stops again.

                          Will run test files tomorrow and share results.

                            So your problems seem to happen when you print slower? mmh, interesting...I always print at 60mm/s internal perimeters and infill and 40mm/s external perimeter....have you configured PA as well?

                              do you have a report of the window that was detected by the end of the print?

                                So far my test files have failed to identify the problem. I can see that @alankilian has an abnormally high AGC value which I would normally consider out of the workable range, but despite that his results are good.

                                I printed the drywall anchor from @wouldstain yesterday. It showed an expansion of the measured range towards the end. After 13 minutes the range was 81% to 127%, but in the final 3 minutes it increased to 53% to 130%. So I will try to work out the movement pattern that caused that - or maybe it was just slower printing time towards the end.

                                  So far my test files have failed to identify the problem. I can see that @alankilian has an abnormally high AGC value which I would normally consider out of the workable range, but despite that his results are good.

                                  I printed the drywall anchor from @wouldstain yesterday. It showed an expansion of the measured range towards the end. After 13 minutes the range was 81% to 127%, but in the final 3 minutes it increased to 53% to 130%. So I will try to work out the movement pattern that caused that - or maybe it was just slower printing time towards the end.

                                  If it could help I've noticed too that in my prints (when they don't stop immediately) there's ALMOST always a range expansion during the print in terms of max and min limit....at a certain point I thought that the two values could be "incremental" values....

                                    @thedragonlord @wouldstain @alankilian @charlesmc @CNCModeller I have fixed a couple of potential issues in RRF that might have caused spurious under or over extrusion reports. My initial testing suggests that these have fixed at least part of the problem - the window at the end of the drywall-anchor print went from about 53-130% before to 93-112% after. However I have not done enough runs (2 before the changes, 1 after) to prove statistically that the changes have made an improvement.

                                    If you wish to try out RRF with these changes, you can find the binaries at https://www.dropbox.com/sh/xeu30go894p9xbs/AAB5U66SH4wbjKIcX0snUbKxa?dl=0. Caution! These are pre-beta binaries so they have had limited testing. If you are not already running firmware 3.4beta5 then you must read the upgrade notes before installing them.

                                        @dc42 thanks for the update. I'll do some testing with your gcode at the weekend and let you know the results with my 600ppr rotary encoder based sensor.

                                          @t3p3tony I cant say for sure that it always happens when running slower. Only that it did happen this time, with multiple occurrences. I just happened to be printing something that came to a very fine point that I felt would turn out better if printed slower.

                                          gcode attached just in case it would be helpful...

                                            If by PA you're referring to Pressure Advance, I looked at that as a likely culprit as I was getting much more frequent stops before I had the sensor in place and seemed to be having a problem with the extruder outrunning the hotend. It did not seem to make much difference.

                                            Should it be revisited at slower speeds?
