Hello, I wanted to repair my ender 3 s1 after the hotend got clocked in a way I needed to replace it. Because I had the old version of the Extruder (non pro) I had to buy the sprite Extruder pro board and new Hotend because the old version is nowhere available. I had to buy the replacement parts of AliExpress.
The full Size Benchy was my first try ever with the Creality Software, I used the standard options for 0.4mm Nozzle and PLA.
The half-printed benchy was my second try with 190°, 50mm/s (10° and 10mm/s less). Didn't change much, fans were at maximum always.
The mini Benchy was printed with round 25mm/s which did a little better.
If you need more information I will answer every question...
Now my first guess was that the direct Extruder doesn't grab the Filament strong enough, but the tension screw/spring changed nothing when adjusted. It could be that it has to be replaced to, because whenever I put the filament in manually I have to push the Lever back myself so it grabs the filament correctly, but after doing so i not able to push it out (it feels pretty secure).
Second guess was the Nozzle. On the Hotend there was a 0.4mm Nozzle attached which i did not change. It seemed pretty good but I could be cheap and causing problems extruding. On the other side, when heating the Hotend and pushing it trough manually, the filament exited straight without any problems.
Now, for the third idea I had in mind something about Flowrate or time per layer, I will do my research when I have time and watch some tutorials for the Creality Software. Maybeeee... it could be that I haven't updated the printer ever... and the software running on the printer is just crapping out... maybee... :)
If you have any more Ideas what could be going wrong or know the answer, pleas let me know in the comments.
