RU-vid decided this was really important for me to see at 5am so I’ll help out :) it’s hard to hear over the fans, but here’s my best guess: Extrusion/flow is too high for one reason or another. First thing to try, set your flow rate on the machine, while it’s printing to 90-95%. That will likely solve the issue in the short term. Next, check these things in this order if that works: Check extruder steps/mm Check actual filament diameter if this issue is only on this spool. Also dry it out, looks a little wet. Check flow rate in slicer Check nozzle diameter and extrusion width in slicer, make sure they match
@@nathanblanchard8897 Thanks for the tips, I’m quite a seasoned printer and have been for well over 14 years. It’s a relatively new machine, fresh filament, I tried other brands, the same ! Different flow rates, and layer height’s, the same. Brand new hot end, the same. The tip of the nozzle is actually hitting the job, quite hard in fact, it’s worse with supports on big prints as it continually wipes them out ! Doesn’t matter what I do it’s always exactly the same. An acquaintance of mine who purchased his machine at a similar time from the U.K. supplier had exactly the same problem as me, he gave up and bought a different machine !
@@stephenkelly8065 oh nice! I don’t run into many people who’ve been in the hobby longer than me! I’m at 9 years, my first printer was a modified i3 on a custom welded steel frame. Super interesting problem though. The only similar thing I’ve heard of was on a delta printer. There was a marlin setting that had been configured incorrectly, and long, linear travel moves would cause the nozzle to dive an amount proportional to the length of the move. What was happening was as the firmware calculated the movement, the output would be incorrectly compensating for the delta motion system. It’s hard to explain, but the issue would only show up on those long travel moves, and round objects (specifically non arcs, don’t think that was enabled) were many small moves so the droop was nonexistent! I’m sure that isn’t helpful to your problem, since this is probably on Klipper too but I wish you the best on your troubleshooting! Please let me know what you find out!
