Thank you. I recently replaced that gear as well, and the problem has gotten a bit better. I'll be sure to check everything you just mentioned.
I tightened the tension arm and now it's clicking when it reaches a piece of filament that isn't extruding fast enough. So I think that means it's an issue with the hotend not heating the filament fast enough. I'll check the friction of the mod though just to be safe, and I don't think I ever calibrated my E-steps, so I'll have to do that.
Adjusting the tension arm seems to have helped a lot, so I think you're on to something.
I'd watch this, but only if the humans are as scientifically wrong as the dinosaurs were in the original jurassic park. Make him 12 feet tall and hairless!
Honestly when it works it works wonderfully. Most of my problems with my ender 3 come down to me being a dumbass and not taking care of it properly, and/or just the nozzles they ship with it being cheap as fuck and impossible to cold pull.
No joke my first ever successful cold pull was 2 days ago, because I had finally gotten a decent set of nozzles.
If you want to get really serious about printing there are better options out there, but for the cost they really are awesome beginner printers (to be fair I haven't kept up much with printers, so I don't know many other good cheap ones). I mostly only dabble with printing, but my ender 3 pro that I got like 3 years ago has served me very well.
I'm talking more so about HDDs, which were still very prevalent back then. SDDs wouldn't hit similar size to price for a few more years.
I had a mid-range laptop back then that was at least 500+ gigs with a HDD. And when I got my desktop, which was a hand-me-down 2012 dell inspiron from my grandmother, it had a 2TB HDD.
These days SSDs are fast and cheap, so the 1TB standard not really changing a ton has more to do with the switch from HDDs to SSDs.
I could be misremembering a few things here, so feel free to correct me.
Make it completely untyped. Everything's just a string.
