This is my first time trying to print with ASA filament on my K1C.
After 2 failed attempts, I found the cause… my filament spools were still too full, so the filament kept slipping off the spool, which caused a blockage.
After thinking for a moment, I noticed an old cardboard box lying around and thought: you know what, I’ll make the spool bigger so the filament can’t slip off anymore.
I’m also wondering if the Creality PI would be a better option for feeding my filament into the printer?
As you stated, it is not the type of filament but the manufacture who either overstuffed the spool or used an inadequate spool. Did you weigh the spool before printing? If it came in above 1KG, then you got a bonus. But if it came in at 1KG then the MFG has a bad design. Can you share who the brand is?
On the subject of using a PI as a spool feeder. I have one and I really don’t see this as a remedy. If it unspools improperly on your side spool holder, the PI might help but unless you already have one for drying purposes, it’s a pretty expensive solution just to fix a spool feed problem which you’ve already seem to have solved via MacGyvering.
I see a future where you take your cardboard concept and fabricate a more robust solution. But then again… how would one produce such a concept in the real world? 
Wait… I got it! Do you know anyone with a 3D Printer that you can print such a design??? 
But serious, you may want to first look at Printables or Creality Cloud for the 100s of spool holders and print one you like. I see that you may already have a modified one on your current device so clearly you already possess the know-how.
Thank you for your reply, and maybe it’s not such a bad idea to put the cardboard spool enlarger into production, but your suggestion to look on Printables seems better and faster.
As for your question about the brand: it’s from 123D, which I believe is a Dutch brand that sells almost everything, including printers and filament.
And yes, it is quite an expensive solution, but I need to buy a filament dryer anyway, which is why I asked the question.
If you’re considering a Creality Pi, I would look elsewhere.
I bought the Sunlu S2 and Creality Pi at the same time, intending to keep the better unit. The Sunlu was worse, but the Creality Pi was not good. I kept it only because there were few better choices under $100 at the time (03/24).
After a year of use, the Creality Pi looks like typical Creality execution: decent headline specs, poor implementation. The touchscreen is defective, cannot be calibrated, and often requires fiddling just to register a touch. Creality support responded once, then ghosted me.
I had to remove the touchscreen bezel to make the screen usable, and I had to modify the hinge because the lid design is clumsy. The blower fan is another poor choice. Think “hair dryer” - noisy, crude, and not what I would call thoughtful thermal design.
The only real positive is that it reaches the advertised temperature. Even that comes with a caveat: the top and bottom of the dryer can differ by as much as 15C, so the heating is not uniform.
I later bought the Polymaker dryer, which is less capable and only reaches about 50C. I am still looking for a sub-$100 dryer that can reliably hit 80C, and I have not found one.
At this point, I would spend more and look harder at EIBOS. Their designs may be ugly, but at least they appear to be original. The Creality Pi feels like a commodity product dressed up for gadget appeal rather than designed for real performance.
