Ok so this is weird.
Installed a new nozzle and now it appears to be oozing out of the thread joining the barrel and said nozzle.
It appears to be tightened reasonably, so I'm thinking that either something has warped or that the nozzle has a defect of some kind(ie squished en-route by the lovely folks at usps and/or auspost).
Thoughts, comrades?
Means it isn't tight enough, or the threads of the coupling have plastic on them preventing the proper tightness.
Did you tighten it while hot?

miss threaded or flaw/crack in threads likely also

Definitely not. Do you own a Filastruder? How much experience do you have swapping nozzles on it?
Hmm I believe I followed the instructions to the letter, i'll pull it apart again, see if there's goop to clear away.
Cheers Tim!
You could have still gotten plastic in the threads. PLA likes to flow into the threads pretty easily. If you tightened it wihe hot it should have sealed ok though.
Yup, just spent 30 minutes cleaning the crap out of the threads.
It did indeed limit how far I could tighten in the nozzle.
Going to run it for a few hours to confirm the fix now.
One thing I've done is tip it back on the motor so that gravity pulls the hot plastic towards the hopper instead of letting it get on the threads, you could try that.
if you got one of them 90deg dental tools i usually chase the threads all the way down to make sure i didn't miss anything.

no but have threaded and installed more pipe and fittings than all the MM of filament you have extruded so think I know if that can be an issue with even a low pressure leak under 1/2lb PSI much less high temp/pressure and if the pipe or fitting was made in China the odds are 10x greater due to poor material/workmanship
I inspect nozzles and couplings before shipment. Not once have I identified a crack or defect, not once has a customer reported one.
Both parts are sourced from US suppliers that are very well known.
Ironic that I've had far more items made in the US die on me than items made in China... Bias is a strong influence it seems. Except for screws. Chinese screws suck.
Thanks Tim, you were quite correct, solved the leaking.
Onto the next dumb question, what extrusion speed should I expect at around 145 degree's C for PLA? Having a tad of a problem with speed vs diameter it seems.
Anything under 150 the extrusion rate slows down and anything over 155 the diameter shrinks to about 1.5mm.
How'd you dry the filament? I'd expect 6-15in/min.
You may have to increase cooling, add some fans or use a larger fan. Depends a bit on ambients, etc.
Grabbed one of those toaster oven type devices, so far I've just been using it's medium setting for a few hours at a time to dry the pellets.
Hmm, perhaps I'll print up a multi-fan holder device.
Which fan are you using currently?
1.5mm will probably print and feed ok though. You could also go to a 2mm hole in the nozzle. I drilled it to 1.75 for you IIRC.
Just the one you shipped it with running as per instructions.
Hmmmm, I'll see what happens tomorrow when I have the time to run it for the whole day, and do some test printing etc.
I'm really not bothered so long as it works and in reality I'm sure the Bulldog will handle smaller diameter pretty well.
Gotcha. Yeah I'd try a more powerful fan if you have one available.
