Here are the details:
- Creality CR 10-S5
- BLTouch leveling sensor
- Micro Swiss Direct Drive filament upgrade kit
- Bed is 66 °C.
I tried dozens of temperatures starting at 205 °C and going all the way down to 180 °C pretty much 1 °C at a time. The present temperature of 188 °C seems to generate a higher stickiness to the bed than other temperatures.
I have also adjusted the flow rate down to 47% and that, although it did help with the stringing, didn't fix it completely and made the whole print super weak. I have discovered going below 80% is structurally a bad idea. I wouldn't mind having it at 90% either.
I am trying different retraction speeds and distances now currently testing 5 mm and 70 mm/s retraction. Previously I tried 4 mm with 60 mm/s and it didn't help.
Using a lower filament flow rate (about <60%) did prevent it from going all the way across at approx 50 mm/s, but alas <60% is too weak structurally. And didn't solve it completely. The tips had a Y-shaped split top on both sides with the one side of the Y being straight as it is part of the tower.
Any suggestions to rid me of this are welcome. Reminder flow rate below 80% is too weak, and 188 °C is preferred.
