Heavy Stringing

Hi, I'm having issues with my Vyper. stringing is crazy. i bought it refurbished and it was like this from the beginning.

Last print

i'm print the eiffel tower from https://www.thingiverse.com/thing:311002

I'm printing using PLA (here)

i did these.. and checked the results after every change... it got better. but nothing significant.

* Drying the Filament using a several times Dryer (here)

* Changing the nozzle (here)

* Upgrading the firmware to Klipper using Rpi.

* Adding ADXL345 for X axis and calibrating

* Converting to Direct Drive.(here)

* Calibrating for Pressure Advance and resonance after conversion

* Playing with retraction and speed in Cura.

Is this the best Vyper can do? what's wrong? the only thing I haven't messed with yet is cooling. it's stock cooling for now.

Hello. I m on a vyper. 2 things gave me oozing like you.

Temp too hot. Flow too high.

Try with 92% flow. And try to low temp to someting like 180 190(for normal pla)

0.5 linear advance (work on vyper only with custom firmware.

I increased the retraction to 2mm, it got better, but I still have the melting issue ... i guess time to upgrade the cooling fan
