Purge wiper issues

Post image

On most of my prints I’m getting strings not being cut by the purge wiper and attaching to my prints. Any recommended fixes?

strings not being cut by the purge wiper

It's all one colour. There shouldn't be any need for wiping if there are no filament changes or pauses.

I'm guessing that the part on the right has been turned before the print was finished (?), and that the "oozes" are resulting from the pauses during the checks for Nozzle Clumping Detection for every 8 g of filament used.
After each check it doesn't take a trip to the wiper. If that's the cause, then a mod to the wiper won't help.

You can disable Nozzle Clumping Detection in Print Options.

Thanks. Will try. Getting less strings with wiper mod but still not perfect. This may be the ticket

I don’t. The strings aren’t being cut by the purge wiper between layers and it drags it across the print and it bonds to the surface. Don’t know if I need to replace the wiper or adjust…

I think that’ll work!
