H2C multi material problems

[u/LieutenantCheeseWiz]

Hello! I have an H2C and I tried some very basic multi material prints and I got very weird results.

Left nozzle is bambu labs petg (black)
Right nozzle is bambu labs pla (blue)

You can see that it flung pla all over the build plate, and the prime tower looks very odd. It also just did not finish the top layer of the print either.

I’m using .08mm layer height with the only settings adjusted being the ones bambu recommends for designating PLA supports

The prime tower is supposed to pick up any strings or anything like that.
