Looking for some pointers. I have to print some rather large parts and I want to do so with NylonX. But I have never used it before. I've read that PVA on glass is good for adhesion, but I'm a little worried about the hotend temp. Last year, I was printing parts with TPU, which has a very high extrusion temp. I ran into a problem with the extruder because it apparently got too hot and just stopped pushing the filament through the hotend. I really don't want this to happen halfway through a 20 hour print. I have some heat sinks on the back of the extruder housing and I'm wondering if I should attach a fan to that heat sink. Anyways, any help would be appreciated. I've also got some Colorfabb XT-CF20 to work with. p.s. I was going to use Robo CF PLA, but they stopped carrying it! That sucks because it really prints well.
