Eryone Rainbow Silk Issues

Gents bringing this to forum as im kinda stuck a little. So some of you may have seen i had issues with Eryone filament i posted on the facebook page with it either printing thin air (P1S) or bad adhesion Between layers. Eryone did contact me and said dry it ( i had done already but hey ho did it again) Last year i must have done 400 rolls of their Candy/Sunset etc rainbows without a hitch. I then had to change vendor due to availability of the stuff, then we managed to get 40 rolls. Thus far 5 of the rolls have exhibited the same issue. We have tried them on differing P1S and X1C and also A1 and it all seems to be very touch and go as to if itll complete a print. I can check on them 4 hours and alls fine, then go back 4 hours later and for the last 2 hours its printing in the air. Ive dried them mulitple times to 20% Humidity in a Sunlu S4 at 50 degrees. ive tried printing my normal way Generic PLA Aux fan off at 220, i then tried Bambu basic setting at 230… But still bad. Now in the 10 years of 3d printing i have maybe 1 diff roll but i now have 5 of this rainbow differing rainbow shades so it not consistent to Candy colour…

The biggest thing i see is when i unload the filament i can see where the extruder has ground away at it. i thought maybe a duff extruder gear, so cleaned them. But as you pass the roll around the 13 printer we have the issues follow…Im starting to think recipe change but anybody any input of what to try next. I even printed on .16 HQ as this slows it all down but no still same…

Based on the information provided, it seems like the filament is suffering from heat creep: Heat creep and how to avoid extruder/hotend clogs | Bambu Lab Wiki

it is recommended to read the article and ensure that you keep the front door open / top cover open when using this filament.

Silk filament can be more prone to heat creep, as it can soften quicker when the environmental temperature is higher.

It is also recommended to use the Generic PLA Silk profile for this with 220-225C for the nozzle temperature. Silk filament usually prints hotter, and can benefit from a lower volumetric speed to ensure better adhesion

Thanks

This is how I generally do it glass is off and doors are open with generic stock settings running 7.5

FYI this is good for the P1 and X1 but then we have to look at why the A1 should show the same symptoms and that’s open design

I ran more temp towers last night shine of the silk as we know starts to kick in at 215 and gets better the hotter it goes

I’ll try some tests today but I’m also seeing lots of people online complaining about tolerances of this filament causing the grinding that I see

Thanks

Just an update tried with a 0.6 nozzle still the same, it seems as though the extruder is grinding through it. I may have to slacken the spring somewhat so that its not as tough on the filament, its a shame though because across 13 printers its the same, meaning i now have to adapt at least a few to cater for these rolls… Everything else is fine…
