    I never comment on videos ... but you literally saved me with this discovery! Bought some red Esun PLA+ ... seemed like it was saturated/wet straight from the vacuum seal ... turned out it does not like retraction! Followed the steps above (set retraction to 2mm in Cura) and yes, one of the most beautiful prints I have done to date! My other 20 PLA spools have never had any issue with retraction. Thanks very much for sharing!

    I was having this problem on my Bambu X1C with ABS and ASA and I knew it wasn't moisture because I always thoroughly dry my filament. I tried temperature, cooling, speed, but nothing really changed it until I tried reducing retraction from the 0.8mm default to 0.6mm and I got the most beautiful ABS print I've ever produced. Thanks for the great advice!

      Somehow this problem occurred on my X1C today. Printed a lot of ABS and out of nowhere I got these pockmarks. I thought Retraction couldn't be the problem since I've already printed some ABS before. Gonna try it out with 0,6mm and if it doesn't helps maybe my Nozzle is partially clogged.
      What I wonder is why is it happens randomly when there isn't even a seam near of it

      Yup. I used an overture matte filament and had the same issue. I was able to find an obscure post on Reddit that gave this exact same solution to the problem and we were all using different colors of overture matte filament. prints are coming out perfectly fine now.
      Although we just changed it to 3, not 2.

    I brought some different brand PLA few weeks ago that never use before and heard popping all the time while printing. I tried different setting, like printing speed, acceleration speed, jerk speed, flow, even lower the nozzle temperature exceed their recommended, still pop!!
    After i saw your video, turn all setting back to default and set the retraction distance to 1mm, all pops gone and print like a cream now.

  • @ariadnedanelle
    @ariadnedanelle 11 месяцев назад +1

    I have this matte rainbow that is so difficult to use,. I increased the retraction distance and decreased the temperature to 195 to help reduce the high amount of stringing. This helped a bit but then I got pits and under extrusion from too much retraction. So I increased the flow to 105 and this fixed the under-extrusion but random pits continued. (filament dried multiple times so it was not moisture). Also, i think turning off combing is a good idea if the under extrusion is occurring near the seams. I have now turned the retraction distance and speed back down because otherwise air is pulled back into the nozzle resulting in popping and pits. This issue seems to only exist on mattes. It is much easier to tune these on regular pla and even silk. Maybe because matte is so soft and seems to melt at a much lower temperature (i used a heat gun on low to remove stringing and the whole model warped!), I even tried printing at 180c expecting constant clogs but it actually was fine. But still stingy. Maybe mattes should be printed much lower temps than suggested. Mattes also seem less dependable for settings between brands and colors even.

      On my side, my problem was due to, the nozzle was not tightened properly. There should be no gap in between nozzle and heatbreak. I had to ensure that the nozzle has a slight gap of around 0.5mm from heatblock, to ensure that it squashes the heatbreak tightly

      I'm using Sprite Pro, with the same 0.8mm retraction. I'm using a lot of polyterra's filament, and it's slightly abrasive, try a new nozzle, that fixed my problems instantly. And in general if you're printing with good settings and getting good results, you are not changing anything, but suddenly your models starts to suck, and you are getting a lot of pockmarks, gaps in layers, poor adhesions etc., it's time to change the nozzle. Also make sure filament is dry, just because it's a fresh new roll doesn't mean it's dry. Polymaker recommends 6 hours in 55c for polyterra PLA.

    Maybe this will cause stringing, try adjusting nozzel temp and flow rate and lower print speed. if not, check nozzel or replace it, and check extruder. If still not solved. maybe there is an issue in the printer software.

    • @architech_the_engineer

      Actually, it only cause stringing if you turn it down too much. If you find that sweet golden spot, you will avoid both stringing and pockmarks (from my experience)

      I have a 3v2 as well and despite running old G code and new (old and latest cuts)and no firmware updates on the printer I now get pockmarks and sometimes bubbles. I have cleaned out and replaced the extruder tooth wheel and reduced the extractor seemed to help. I have replced nozzle and bowden tube couple times my next step will be adjust the flow a touch I'm thinking maybe the hotend is starting to go and its not heating enough. I have a p1p coming so I'm on the fence about bothering to replace the hot end( fans running noisy too)

    • @architech_the_engineer

      The vertical line is called seam and you can never really get rid of it, CURA allows to hide it by starting the layer lines in random spots, but to me it looks even worse. I’m afraid the seam will always be somehow visible in FDM prints

  • @chopperpl
    @chopperpl Год назад +2

    2mm retract distans is not recommended for bowden extruders. It may lead to stringing. It worked in your case, because your ptfe tube is not loose yet, but will come over time. Also, it appears your settings of 6mm was retracting too much causing gaps. You should have tried changing settings down in 1mm incrementals until you find your sweet spot. I had a same issue with prints, but in my case it was the popping fillament. I had first tried your suggestion, but it was stringing like hell.

    • @architech_the_engineer
      @architech_the_engineer  Год назад +1

      Thank you for the comment! In my opinion it highly depends on the printer, and on the filament as well. For example, every other filament I used works perfectly on 6mm, but Lavender by PolyTerra only works with 2mm. I strongly ecnourage everyone to try tweeking this setting, as I believe every situation is slightly different. And that is true - the lower the retraction distance, the more it is likely for stringing to appear. It is tough to find that golden point of balance, but I believe it’s possible within few attempts. Best of wishes and thanks for sharing your experience! ♥️

      Sorry to here about nightmare,,, but we all get them them from time to time,,lol
      specialty filaments are a pain the ass,, so tune printer in with Esun PLA+ Grey is colour to see whats happening with the quality-
      Direct Drive System - PLA+
      0.5mm retraction (i even use 0.4mm or 0.3mm at time with low nozzle temp) 0.8mm is to high for direct drive-
      Retraction speed 30mm/sec
      Never use Coasting on a direct drive
      Here are the Basic settings for Slow but high Quality print- PLA+
      Cura 5.4.0 - on SV06+ but you can use these setting on any Slicer/Printer-
      Always use a XYZCube because it easy to identify problems and see how you go,,,
      Layer height- 0.2mm
      Layer width- 0.4mm or 0.5mm
      Perimeter Speed- 30mm/sec
      Top/Bottom layers- 40mm/sec
      Infill speed- 60mm/sec (20% Grid)
      Jerk- 7
      First Layer Speed- 20mm/sec
      Flow Rate- 90% to 100% (reduce to 95% or 90% instead of 100%) if over extruding (rough surface finish)
      -----------------------------------
      PLA+ TEMP 200deg- ( but do used 195deg at lot- if printing faster increase to 205 and 210
      BED TEMP 45deg to 55deg
      FAN 80% (Start at Layer 4)
      ------------------------------
      3 Walls Perimeters- (1.2mm or 1.5mm) (depend on witch Layer Width you picked)
      5 Bottoms Layers- (1mm)
      Surface Patterns- Lines
      Glue Stick- lightly tap Up&Down on bed area (do not Rub in) if having issues with print sticking to bed-
      Adjust Z-Offset so first layer is slightly squashed -- ( will take a few attempts)
      *Note- this above list is a Its a cut&paste settings i use to help other people with problems-
      Acceleration is different for all printer but i use- between 800 to 1500 for everything except perimeters which will be 200 to 600-- if your using 5000 or 10000 and wonder why you have problem please go away and don't waste my time-
      PS- A faulty wire (semi broken) or the Extruder Stepper Motor is a dude ?-,
      i had a lose wire inside the plastic connector in one of my stepper motors that worked 95% of the time,, it drive me batshit crazy for weeks until i found it,,,
