Hi all, I have bought a second hand Creality Ender 5 pro. So far so good. I checked the belts, tightened the bolts (where needed) and successfully ran it for a week before deciding “you know what this printer needs? Klipper firmware.” So off I went and installed Klipper.

Ran though all the requisite calibrations, so now the extruder extrudes 50 mm (+/- about 0.2mm) when I ask it to, my calibration cubes measure exactly 20 x 20 x 20 mm with less than 0.1mm deviation. PID tuning for hot end and the bed. But the stringing. The stringing!

The filament is 3DJake ecoPLA that I opened two weeks ago.

See picture attached (and apologies for miswriting the ^2, I had misremembered). Temperature, retraction, it doesn’t matter. With stock firmware the retraction worked well at around 4.5mm retraction at 40mm/s. I can’t get the stringing to stop here at like 80mm/s and 8mm of retraction and I am at my wits end.

I would greatly appreciate any pointers you guys might have for me!

    Every time I think it’s not the filament being wet, it’s the filament being wet. Was chasing some blobbing and stinging on petg, swapped to a new spool of a trusted brand and it pretty much all went away. I really should dry all new spools but especially cheap or unknown brands, I’m definitely going to dry before using.

      The pla being wet is probably the only real possibility left at this point. I’m going to try and dry it today, thanks!
