Ender 3 sudden stringing issue!
hi, i have been printing with my ender 3 for a couple of months now and overall have had very few issue and only very minor stringing.
yesterday i was printing some links for a cable chain which i have printed before without issue but this time they were covered in stringing! both thin whispy stringy bits and the type that look like trees/branches.
ive now started running some tests by printing these tet peices and messing with some settings...

im on my 5th test now with no change.
my original settings were...
nozzle temp - 210
bed temp - 60
layer height - 0.1
flow rate - 100%
print speed - 45 mm/s
enable retraction - yes
retraction distance - 5mm
retraction speed - 50 mm/s
extra prime amount - 0 mm3
so far i havent messed with the extra prime amount but have brought the nozzle down to 190, bed still 60, flow rate down to 95% (in 2.5% increments), print speed between 45-50 mm/s, retraction distance 4-6mm, retraction speed between 30-55 mm/s - all of this and still no improvment :/ im puzzled as to why this problem started so suddenly, one thing i have noticed as well is that as the nozzle is heating up it slowly oozes material.
does anyone have any sugestions?
