Persistent Stringing Issue on Prusa Mini+: Seeking Community Input

Hello Prusa community,

I hope this post finds you well. I'm reaching out to share my experience with a persistent stringing problem on my Prusa Mini+. I've been troubleshooting for quite some time now, and despite making several changes and upgrades, the issue persists. I'm reaching out to the community in the hope that some experienced users might have insights or suggestions that could help me resolve this frustrating problem.

Here are the details of the changes and upgrades I've made so far:

New Bowden Tube (Extruder to Hotend): Replaced with a new original tube.

New Nozzle: Replaced the nozzle with a orignal one, to rule this out.

New Bowden Tube Inside Extruder: Installed a fresh tube to eliminate any potential internal obstructions.

New Heatbreak and Hotend Bowden Tube: Upgraded to a bondtech heatbreak set, because above fix did not work.

New Extruder Stepper Motor: Replaced the stepper with a new prusa one.

Different PLA Spools: Tested with various PLA spools from different manufacturers to rule out filament-specific issues.

Despite these efforts, I'm still experiencing stringing in my prints. 

If anyone has encountered a similar issue or has successfully resolved stringing problems on their Prusa Mini+, please share your insights. I'm open to trying new approaches or looking into aspects I may have overlooked.

I own 4 prusa minis now and this one has the most run hours, but the whole filamant path is now changed so now I am out of ideas.

Thank you in advance for your time and assistance.

Happy printing!
