I’ve been doing a lot of work to un-do the calibration errors I caused (long story short, don’t use a feed rate of 3500 when moving the Z axis!) and I’ve noticed that my hot end is leaking material all over the hot end section. I’m using Lulzbot Translucent Blue PLA @ 185 and I don’t know what to do in order to stop this. It appears to be leaking where the PEEK section mates to the heater block.
As it is now, the hot end is coated with a thin film of PLA, from the top of the heater block down.
I’ve never run the hot end past 195 so I seriously doubt the PEEK is damaged. The trans. blue never gets run above 185 because that appears to me to be the “best” temp for it that I’ve found. The hot end has always leaked, but I assumed it was because I was running junk white PLA that I’d accidentally over-heated (it got a bit runny at 195), but I doubt that this is normal behavior at 185.
