Prusament issue - filament catching in the roll notch

Hi everyone,

Not sure if this is the right place to post about Prusament, but I haven't found a category for it.

I would like to have the community feedback about an issue I have encountered on the Prusament (which I love by the way), and that I strangely haven't seen much talked about.

Do you know the notches that are seen in the Prusament rolls and that are used to hold the tip of the filament in place in new rolls? For that purpose it is a smart design. But when printing, occasionally the filament gets caught in the notch at the rim of the spool, and that has caused all my printers (I have 4) to have a X-axis crash. It happens especially on taller prints, which I think is understandable, as the filament is oriented more horizontally and it is harder for it to get out of the notch.

I am trying to patch the issue with some adhesive tape to cover the notches, but I am surprised to discover this issue...

Has anyone else seen this issue? How do you deal with it? Is Prusa looking into it?

Thanks everyone!

Print and attach one of these filament guides.

 

I have tried many and this one is just outstanding. Should be standard in the kit.

 

I do full Z height prints with Prusament without issues.

 

I recomment PETG, a 0.4 nozzle, 0.15 layer height, 3 perimeters and 10% infill.

Oh, by the way, I forgot to ask - did you run into the same issue I did?

I printed the part you suggested, and it does not fit on my spool holder, because it is to tall. Removed a couple mm, it fits nicely.

No, I've never had the issue you described with the filament catching as I've always run the guide.

 

Unless they have changed (unlikely, but need someone with both models to confirm) the stock spool holder in the MK3S to MK3S+ upgrade, it should fit perfectly.

 

Make sure it's attached to the correct gap and is installed the right way up. 🙂 👍

RE:

i just ran into this EXACT same issue. I was notice I was getting a layer shift and couldn't understand why. Then I caught it happening where the filament would get pulled into the filament spool clip/slot on the side wall like you mention and sure enough, it snagged and yanked the X-axis over.

For now I'm just taking some time to put some clear packing tape over each filament slot on a new spool before loading it up.

I'm not using a guide so it sounds like I should be. I'm printing on an MK2S so I'll have to see if there is something good to use there. It would be nice if Prusa could fix this in the spool design though. It's a feature with good intentions... but you know what they say about good intentions 🙂

RE: Prusament issue - filament catching in the roll notch

Nothing has ruined more prints for me than this.  Such an odd choice to make, having spent so much to improve 3d printing, to then force us to print and set up and use a guide when the better answer is to stop doing this!  

No other brand I’ve seen does this.  My MMU is set up in and it’s not functional for me to use a guide due to space.  I’m sure others will have similar situations.

Prusa, stop using this method, please, I beg you.  I want to continue using your filaments and I love my PRUSAs.

thanks.
