Thanks!

Thank you for your kind words!

The voice is not mine, but spoken by Tim de Man!

@@VincentGroenhuis kan tim beter engels dan jou? (Ik heb geen idee waarom er ik stond)

@@vonckjenl3633 I think so!

I must compliment you on the excellent balance between music and voice. It is way better than most KZfaq videos which would be better off without any music as it is too intrusive. You, however, are masterful at this difficult balance!

@@lkibbler "Ich muss Ihnen ein Kompliment machen für die ausgezeichnete Balance zwischen Musik und Stimme. Sie ist viel besser als die meisten KZfaq-Videos, die ohne Musik besser aufgehoben wären, da sie zu aufdringlich ist. Sie sind jedoch meisterhaft in dieser schwierigen Balance !" Wenn´s so schlitzohrig gemeint ist wie es klingt - dann mein Kompliment ! Bleibt trotzdem die Frage, warum YT nicht endlich die Möglichkeit schafft, Text zu hören ohne von "Musik" belästigt zu werden. Das gilt natürlich ebenso oder noch mehr für´s TV, das ja mit seinen Zwangs-Gebühren diktieren kann. If it is meant as sly as it sounds - then my compliment! Still the question remains why YT does not finally create the possibility to listen to texts without being bothered by "music". Of course this is also true for TV, which can dictate with its compulsory fees.

What is the title of this song you made!

@@johnny5634 No title, just wrote it for the video =) . I have plenty of original work on timdeman.bandcamp.com if you'd like to hear more!

Glad to hear that my ones will always be cooler than yours ;-) But I've seen pretty nice color combinations in the wild though. Have fun!

No but to roll up the filament after the change if you print several filaments, so that it can not get tangled. Useful for e.g. MMU from Prusa or ERCF for Klipper printer

it keeps the filament in tension when you unload the filament from the printer.

Purge, correct! Prusa MMU2. There is also a separate small wipe&prime tower.

Yes, PLA spring gets weaker over time, there are a few good remixes around with PETG spring inside a cup.

@@VincentGroenhuis Thanks for the quick reply. I'll look around for the PETG remixes. I like my setup a lot...don't want to change. 🙂

Yes! If you put the clutch too tight then the spring would eventually try to destroy itself.

Type "608"! A bunch of them are supplied along with the MMU2.

The clutch will let it slip.

Try lower temp, higher speed, higher cooling fan, no Z hop on retract, different material type (PLA or PETG). Otherwise I don't know but you can also revert to the simple v1.01 spring.

Print the modular v3.4 spring which is super easy to print.

Same issue, but does work on top spring releasing, printed three times no support, no raft/skirt or brim and reduced bed heat nozzle temp etc. 2nd layer height...nothing works to free inner bottom spring...fused to bottom circular shroud as you say.

you dont

pretty sure unless you are making multi filament prints on the regular you don't

RESURRECTION! When the Printer raises and when a Multi Material Unit retracts filament, That material goes back toward the spool. Without the Slip Clutch system, that filament just starts creating a rats nest and begins falling out the sides of the spool or worse, the filament gets stuck under more of the same material of the spool and stops moving all together.

Yes, a 3 kg stand is available!

Also fine for normal use :-)

@@VincentGroenhuis thank you so much for replying!!! I really appreciate it!

Yes, you need ~500 mm retraction for het multi-material MMU2 setup!

;)

No, there is a clutch

No

it is basically meant to keep the spool from having too much slack as the extruder moves toward it pushing the filament back toward the spool. Sometimes filament can slip off the spool if there is too much slack in it. I personally think best example for this would be on Delta Printers because when the print finishes it homes to the top pushing the filament back toward the spool in most cases. So that is where I think they type of retractable spool system would work best.

Its for multimaterial units where you have to retract huge sections of filament while switching filament. If it doesnt go back on the spool it will get tangled and jam

The issues are: filament load/unload problems, and multi-material setup (Prusa's MMU2) taking up too much space

Yeah, it's pretty much a solution searching for a problem.

I use "wipe to object" (the spring) so the purge block is super small!

@@VincentGroenhuis ahh.. thanks! That was it! Thanks! I'm going to do that.

3D LAC!

@@VincentGroenhuis Thanks, great project btw

3D LAC

Both should work. Be sure to use v3.4 for the spring. I normally use PLA but that is a personal preference.

Type "608", any subtype is fine, eg 608ZZ or 608RS.

@@VincentGroenhuis Thanks just saw this and was like man this could fix the issue of my filament getting loose and falling off spool while printing and will be a quality of life thing.

Normal skateboard bearings, or better called 608rs/608zz

Most likely Makerpoint Yellow Green, ordered back in 2017: www.makerpoint.nl/nl/makerpoint-pla-750gr-yellow-green.html

There is a special version for Repbox: the RepRewind!

Yes, see Thingiverse

Bearings type "608" were supplied by Prusa with the original spool holders, but can also be ordered from various mechanical engineering shops. You can also use skate bearings.

@@VincentGroenhuis thank you!

Depends, what do you need?

I use the MMU2 which allows to switch between five colors!

@@VincentGroenhuis thanks

Where exactly is the friction?

@@VincentGroenhuis The spring does not unroll smoothly

@@xAaronGamer Try the v3.4 modular spring

@@VincentGroenhuis that's the version i tried, i wrote it

@@xAaronGamer Oops, ok. Can you make a video, then I can look at it. Hard to help from a distance. Why is the friction there? Parts rubbing against each other? If you remove the spring does it roll smoothly?

With purge block! Yes, it is there...

@@VincentGroenhuis purge block not on the build plate?

Purge block is on the build plate. It is small as "wipe to object" is also used.

@@VincentGroenhuis oh ok, I might have missed it on your video

@@alvint4944 Found the purge block yet? :-)

Check the slicer output layer view, is there a gap (skipped layer)? If yes: you can reduce layer bonding by increasing printing speed and fan, by lowering temperature and/or by changing to a different material. You can also try separating using a knife from outwards.

@@VincentGroenhuis Merci! Thank You:)

That's why I designed the v3.4 modular spring!

@@VincentGroenhuis to make this print right I had to enforce supports. Which makes it very difficult to post process without breaking the spring. I would also recommend making the spool nut cone shaped so when you screw it on it auto centers the spool. Some of the nut pieces do this if you put them on backwards. Ibeleive there is also a way to increase spring tension by baking the spring at 175 degrees for 20 minutes or so. Not sure on that. Mostly a good design, update the instructions with print tips for the spring.

You don't need supports for v3.4 modular spring

The spool nuts already auto center the spool 😉

Worked no problem for me, no raft, no supports needed outside of main stand unit

If you have a multi material printer like the Prusa MMU, it helps keep the filament from getting tangled

not much use for single material printer.

Так оно разработано для MMU2, там ретракт неизбежно будет добрый метр

Flattened by your comment!!!

Where's your design? yeah thought so..

@@drood78 I don't need to design one, but if I did it wouldn't be as crap as this turd on wheels. Speaking of turds hi.

Prusa's MMU2 (multi-material unit 2)

@@VincentGroenhuis Aha ok, so not for me. Thanks anyway.
