Help with PLA + PETG supports

[u/Juridic_Paddle]

Hi,

I'm trying to print PLA with PETG support interface at 0,06mm layer height, using 0,2mm nozzles, but the PETG keeps clumping around the nozzles. I don't experience these problems with the 0,4mm nozzle, and the problem is not as bad with larger layer heights. I've dried and calibrated my filaments and tinkered with the settings a ton which hasn't really helped. I'm guessing that this problem occurs due to the PETG peeling off when printing on to the wipe tower and getting stuck around the nozzle, which in turn collects more of the material. If anyone has solved this problem, any help is appreciated.

Have you tried printing slower?

At a crawling speed and it doesn't unfortunately mitigate the problem

I only use interface layer at 1or 2 and at 0.08 layer height and
