Filament Autoloading on Original Prusa MK4

The Original Prusa MK4 is built with everyday users in mind. Loading filament is a breeze, and we've broken down the whole process to show you just how effortless it can be. The MK4 makes 3D printing easy and user-friendly, making it more accessible to all users.

Dont forget to say to cut the filament with an angle, I was a complete total newbie, MK4 is my very first printer, and I didn't know why it wouldn't load. Now it works absolutly flawless. Exceptionnal work.

One thing I really like about the MK4 over the MK3 when unloading is that the MK3 requires you to push a button and then pull the filament out. The MK4 just does this automatically, and also does a better job of making sure the melted filament on the tip is not causing obstructions during removal. I've had my filament get stuck a few times during unloading on my MK3. Usually because I walk away and come back to a cooled down filament inside the PTFE tube. I think the metal tube on the MK4 fixes all of that.

How to load filament onto your MK4: load filament onto your MK4

[kailin]

Please fix the amount that it purges, it’s way too little and the Hall effect sensor can be faulty and doesn’t recognize filament is loaded sometimes so I would have keep removing and inserting filament until it does or I have to recalibrate the sensor, I’m not the only one with this issue. Other than that the printer is great.

I hope a future update for the Mini work like this..

Hey what about adjusting the filament guide roller tension. What Nm should the tension rollers be set to for PLA, PTEG and TPU?

[ejon]

Isn't this already supported on the MK3S+? 🤔

Looks easy!
PRUSA please send me a MK4 to review.😊

Even though the XL you announced 2 years ago, the MK4 (announced half a year ago) was released earlier and is receiving much more attention. As an XL user, I'm a bit annoyed. It seems that the XL isn't getting as much attention. There are always "MK4", "MK4 improvements" and "MK4 Tutorial" topics from Prusa. I really feel like the XL is missing out (at least) on promotion similar to how you promote the MK4.

Same on all prusas - my prusa mini has the same feature with filament sensor installed

My school's mk2.5 has this option. Why is this video even required?

[joshuaisaacs]

Is it just me or is the MK4 the biggest flop of the year?

[awklerjawkldjfklas]

Is this the feature that you guys boast to make a video out of in 2023? Sorry but I am ashamed..
