Lumpy Purge Tower causing print failures.

I'm getting a lump in purge tower causing prints to fail.

I'm printing TPU with PLA supports.

On change over the nozzle seems to pause for a second over the purge tower and either oozing or nozzle heat is damaging the tower.

After the lump gets too big it knocks over and the print is ruined.

Any advice is appreciated.

I used to have this on MMU2 prints but couldn't find a solution then either.

RE: Lumpy Purge Tower causing print failures.

You could try to reduce the "Multitool Ramming volume" and "Multitool ramming flow" (under filament -> advanced ) - should make the blob smaller
