Master Filament Settings: Temperature & Retraction

[@mamatuja]

Why did you have more stringing in the last test than the test before?

[@kerseyfabs]

In the last test, it goes to a very small point, so there is less time for extrusion, retraction, and wiping as you go up to the peak. The previous test was the same thickness from top to bottom. You'll see that lower on the last cones, the print is pretty clean. With some filaments and enough time spent, you may be able to get those peaks clean using the same methods I outlined. I left that in the video like that to show not all tuning will result in perfect results, it all depends on the filament, your printer configuration, and time spent.

[@mamatuja]

@@kerseyfabs Could the stringing be farther improved by better part cooling?

[@kerseyfabs]

I'd have to say possibly but unlikely. It would probably be better retraction or lower temperatures. There are tradeoffs usually though. Lower temps = weaker parts More retractions = possible retraction artifacts

[@mamatuja]

@@kerseyfabs Have you done any tests at higher speeds? 150 mm/s or higher?

[@kerseyfabs]

@@mamatuja Not on this printer. It really isn't built to go that fast.

[@kerseyfabs]

Thank you very much! Happy to have you.

[@leonardomarquez7914]

I like the fact that this video shows honest results where there will be some amount of stringing anyway. I've seen other videos where they ALWAYS end up with perfect prints with not a single string. I wonder if some of them have been passed through the hot air gun before filming. Nice job!

[@leonardomarquez7914]

It's like when they photoshop magazine covers... You get so frustrated that you can't get the same looks at home, LOL.

[@kerseyfabs]

I appreciate that. While perfect results are possible when everything's working really well and you have fantastic filament, I did think it was more educational and reassuring that this is what usually happens.

[@BitesizeUGC]

Another great video. Helped me dial in my settings for ASA, which I have finally gotten to print beautifully. Thanks again, Kris.

[@kerseyfabs]

Great to hear! No problem!

[@Darkwingdad]

Great video, many enthusiasts early on fail to learn these steps & it reflects on there prints & often gives headaches. My tip: get a filament you like, dial it in with what’s shown here & stick with that filament. It’s not worth the trouble to save $2-3 swapping filaments

[@kerseyfabs]

Great tip! It will save you time and hassle. This tip specifically applies to people that plan to finish their prints, not leave them raw.

[@Darkwingdad]

@@kerseyfabs I think both will benefit though! We all appreciate videos like these, thorough & precise!

A very good review. I like the way you went through step by step and showed your results.

Thank you so much Rocky!

Great video I’ll save it and try this tonight thank you

[@AkiraFurball]

If you have the parts for calibration extension installed, which I assumed was installed by default as it was in my cura, there is a gcode script specifically for temp/ cooling towers which will insert all the temps with one quick script.. MUCH easier ;)

[@kerseyfabs]

I don't see that plugin listed anywhere in my Cura installation.

[@AkiraFurball]

@@kerseyfabs Its in the market place, I assumed it was installed by default because I didn't install it but it was there in the extension menu.. Maybe because I use manjaro Linux.. Some useful stuff and scripts in there, worth a looksie ;)

[@sblack48]

I tried those and looking at the gcode there didn’t seem to be any difference in the retract parameters between tower steps dunno why

[@AkiraFurball]

@@sblack48 did you add the custom gcode.. you obviousely have to slice it with the gcode added.. You should see a temp command at the start of each section

[@Coffee2clutch]

Good stuff I was getting ready to run my Ender 5 through the paces and even downloaded the tower a few days ago but was stumped as to how to access the gcode.

[@TommiHonkonen]

Fusion 360 has good test part in the additive manufacturing examples. Might have to try some fine tuning if I get my parts next week.

[@geoffowen7627]

I spent ages with retraction towers, just couldn't get rid of the stringing, after printing a temp tower I noticed no stinging around 190/195, set my temp at 190 retraction at 0.8 and wow no stringing anymore Happy days.

[@kerseyfabs]

Nice results!

[@gdesign123]

Has anyone noticed the overhang test Kersey uses to test the printer will start printing layers in the air around 80-85? Starting from an already printed part then moving into unsupported air seems like where the printer should start. The sidewalls also seem to drag the filament several lines past where the following line should be printing, then it pulls the filament back into the rest of the print. There must be Cura settings to change these print behaviors for better-looking prints on this test.

[@kerseyfabs]

If your slicer is doing that, you can change where it creates seams. "Z Seam Alignment" = "User Specified" then you can choose which side should support the filament.

[@gdesign123]

@@kerseyfabs Thank you :) When rotating the test the back left is the furthest away from the viewer and the default setting. This is not what is needed for this test.

[@skylinefan3465]

I’m doing this exact process today with a new filament, (my first new one that didn’t come with my printer) but I’m having an issue where my printer isn’t dropping nozzle temperature at all?. I’m having to go into the tuning menu and manually change it. Followed the post processing gcode exactly but having the issue mentioned above. Any reason why this may be? Thanks

[@2Old4_This]

Great video, you have been helping me understand and get more into 3d printing. In the video you mention doing extruder steps and flow rate, but I can not find your video showing that. Would you mind providing the link to it here. Thank you

@@kerseyfabs Any chance you have that flow rate video ready yet? The linked video in the i-card was a review for an extruder.

[@danne77sthlm]

Thanks for this one, it´s good to have several ways to test, now I will ad yours to the collection as well, I usually run teachingtech one, but this I will try as well tomorrow if I get time over for it I think that the temperature tower seems easier to read the result from though compared to teachingtechs, but I doing both sure will make it good enough I think :)

[@kerseyfabs]

Anytime my videos can be as useful as Teaching Tech's, I consider it a win! Thanks!

[@emaayan]

Shouldn't you make sure to disable linear advance for the retraction test? Also what do you think about teaching tech's site that generates these models per layer?

[@kerseyfabs]

I have to say, I'm not 100% sure. I don't use linear advance on my machines usually because I don't run that fast. I'd have to test it. I've seen TT video on his site but haven't tried it myself. Yet something else I should try.

[@emaayan]

@@kerseyfabs linear advance has been recommended to me regardless of speed , but i think it would effect a lot of calibration tests

[@kerseyfabs]

Interesting. It seems I need to do a little more research on it. I would love to see if I could see a difference and on what kind of prints.

[@VArt1998]

why don't you check multiple retract parameters in 1 print

[@kerseyfabs]

Technically I guess I could, especially if I'd just make the test print taller.

[@avejst]

Great walkthrough as always Great Video!! Thanks for sharing your experiences with all of us :-)

[@robertfousch2703]

I got my Ender 5 Plus several months ago from Tiny machines (MS extruder and hotend, 0.4 nozzle) and have been using Simplify 3D as my slicer. I want to move to Cura for the additional options and features, but am having a time trying to equate items in the two slicers to set the parameters from a good profile on S3D over to Cura. Can you recommend or even post a video on migrating from S3D to Cura and how to setup an equivalent profile in Cura from one that works in S3D? Many thx!

[@kerseyfabs]

Sorry but I've never used S3D so I'm not familiar with the interface. I also have never searched out a conversion guide. I would think KZbin would have one somewhere.

for my flowrate i got it set to .8 and it always comes out to 8.5 not sure what % i need, as of now i use 100%

steps and flow rate....... I checked the video you linked, I kept skipping around and I didn't see it. I probably should have watched start to finish and not wasted an additional 1/2hr. I had zero luck finding that in the link you provided in the video at around the 3:50 mark.

I'm starting to believe retraction doesn't have a damn thing to do with stringing and blabbing. Adjusted mine from 1mm to 15mm with no change whatsoever.

[@kerseyfabs]

Pro tip: In Cura, change the "Outer Wall Wipe Distance" under "Walls" (you may have to enable it) to the width of your nozzle. In the usual case "0.4" See if that helps.
