Stringing issue

[julien-printerbox]

Hi
I have some issue on 2 printers. Both is working fine before Klipper install. Is there something to modify on Slicer?
On Prusa Slicer firmware retractation is not activated.
On Prusa Slicer, Start gcode is still the same as stock profile. I can't find if there is a start macro on this Klipper config.
Any idea ?

Hi,
After some test, I solve stringing issue by setting a hotend temperature 15°C lower.
It is really strange because I have no issue with this filament profile an other printer.
And printer is cold, ambiant temperature is ok.
Any idea ?
