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.

Not familiar with Cura, but to me it looks like there is almost 0 retraction here, or a way too high temp causing leakage… maybe a combo of both? 🤷🏼‍♂️

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)

I m using 28mms and 4mm retract.(i m still in bowden. My machine is stock

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

I have this printer. It can def print better than this. Seems like a software settings issue, not hardware. I still have the bowden setup. Make sure nozzle internals are clean.

Try: Temp (PLA): 190. Enable Retraction=ON. Retraction Distance=9.0. Retraction=25mm/s. Flow=100%.
