[Troubleshooting] Big stringing problem with flsun SR and Orcaslicer (lemmy.nz)

Ok guys, I'm breaking down and posting here to see if anyone has any ideas. I'm greatful for any advice.

I have an upgraded flsun SR. I recently lost my computer (psu issue, waiting for replacement) and I took this opportunity to switch from Cura to Orcaslicer.

Over-all I'm very happy, and getting some good speeds, but I just cannot remove stringing no matter what I try:

Retraction from 0-7mm. After about 3mm, no further effect
Retraction speed from 30mm/s-50mm/s. No noticable effect
Travel speed and acceleration both high (up to 350mm/s and 6000 accel. No effect
Temp from 205-215 with no effect
Dried filament and different colours, no effect
Wipe on retract on and off, up to 2mm wipe distance and 100% retraction. No effect
Messed with scarf seams on and off, no effect
No effect from layer heights

My setup:

Printer - FLSun SR running klipper with a speede pad
Filament - Esun PLA+
Upgrades - Deported fans, OMG v2 extruder, volcano hotend and high flow cht nozzle

Dry your filament

Dried filament and different colours, no effect

Hey mate, I keep my filament in a dry cabinet at 5ish% humidity, and I've had the same results with two different filaments in there. I even chucked my filament in a food dehydrator at 40C for 12h with no effect. I'm pretty sure the filament is dry!

Drat. I had the same issue as you and nothing was working, despite thinking my filament was dry since it was brand new. I finally dried it in a filament dryer and the problem went away. So, that's usually my first recommendation. Sorry it doesn't help you.

It's all good mate! Thanks for the suggestion. When I first started printing I had that exact issue.
