As this is my first foray into 3d printing, looking for some advice to help reduce the amount of stringing I'm getting when printing parts with spires, or multiple pieces in a single print. I've calibrated the extruder as best I can with the tools on hand, +/- 1mm extra per 100mm. Did PID calibration for hotend and bed and flashed those settings into the firmware. Bed is as level as possible with a warped build plate. Single extruder setup while I wait for missing components as well.
Tried with mostly default Cura settings. 205 print temp, 7.5mm retractions at 70mm/s, result was less than desirable with the building below. tons of stringing between smaller printing areas.
Tried increasing retraction speed to 100mm/s, distance to 10mm, turned off combing and set retraction minimum distance to 0 to try and force retractions everywhere. Also tried another spool of filament and dropped temps another 5 degrees. Stringing was even worse this time around.
Now I'm on a third spool of filament, just printing small stringing tests with two towers (https://www.thingiverse.com/thing:2219103).
Left to right are Cura defaults @190 degrees(7.5mm/60mm/s),
180 degrees with 10mm distance and 100mm/s speed
and then 170 degrees 10mm/100mm/s speed using slic3r instead in case it was a slicer problem. Extruder clicking and under-extrusions there, so definitely can't print that cold.
All three spools are https://filaments.ca/collections/1-75mm-3d-filaments/econofil-premium-pla brand, just removed from the vacuum sealed bags before printing. What am I doing wrong here? And how can I fix this, since it's ruining my bigger prints.
