Polymaker PC-Max on S5 layer bonding not good

[RudydG 62]

I try to print this, with the default settings (recommended / PC generic) in Cura (bed 110, nozzle 280, infill 30%, support with breakaway) Doors of printer are closed.

It prints ok, bed adhesion is very good, no warping, (i use Dymafix), but i do not get good layer adhesion. Same piece in tough pla is better at layer bonding level.

Anyone a clue why?

Just tested same Polymaker PC without breakaway support, now the print is rocksolid, impossible to break.

Does anyone print PC with support? My guess is that the needed fans for printing support, ruins the PC?

Doesn't look like PC is compatible with the breakaway support based on their compatibility matrix:

In my personal experience PC printed very well using PC as the support material.
