I keep having this issue on prints where the first layer has stringy lines that don't stick together.
I've tried the following things
- Replaced nozzle and throat
- Used new filament (to rule out filament that may have absorbed moisture)
- Printed at 180, 200 (my usual temp), 220
- Aligned z stop sensor
- Tried line width of 0.8 (usual 0.4)
- Slowed initial speed to 30mm/s
- Increased flow
- Different Top/Bottom patterns
My print settings as shown in this pic are the following
- Layer height: 0.2
- Line width: 0.4
- Wall thickness: 0.8
- Print temp: 200
- Bed temp: 60
- Retraction dist: 5.5
- Retraction speed: 40mm/s
- Initial layer speed: 30mm/s
- Cooling at 20% after 0.2mm, 0% until then
Printer
- Prusa I3 (hictop)
- Cura to slice
- Printing with PLA
- Have had years of successful prints, issue started happening after a couple months of not using printer
- Running marlin
- Runs auto leveling routine before each print
Let me know if you think there's other relevant settings to this issue. Any help is greatly appreciated, I've been trying to fix this for days. I've tried different models, large and small, but have the same issue no matter the size
