Hi, I am just trying my first attempts with Facilan Ortho PCL on a UM3 extended. The spec sheet recomments 140C,print, 38C bed and 30mm/sec speed. I have created a profile for this and started tweaking settings individually in Cura. The parts I am needing are small and quite delicate. They print OK in PLA.   There is mention in the forum of manually inserting M302 into the gcode file, this doesn't seem necessary as it will build multiple layers on its own but I am having real problems
