I don't suppose anyone out there has any experience with Monsterfil PLA do they ?

I'm having real trouble getting good layer adhesion with it and I've run out of ideas...
- I've printed at speeds from 40mm/s to 90mm/s
- Varying levels of cooling
- Temps from 200c to 240c

But... I can just peel the print apart layer by layer afterwards. (Best results so far were at 240c).

The parts look absolutely perfect when they're finished & theres no sign of under extrusion the layers just will not adheer to each other fully !

What I didn't notice until after I bought the filament is that it's sold as 'lubricated' which they say shouldn't cause an issue, but I suspect thats the route cause of the problem.

Has anyone encountered this or similar issues ? I could do with any advice / suggestions possible.
