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.

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.

Hmm, perhaps I'll print up a multi-fan holder device.

You may have to increase cooling, add some fans or use a larger fan. Depends a bit on ambients, etc.

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.

Both parts are sourced from US suppliers that are very well known.

Definitely not. Do you own a Filastruder? How much experience do you have swapping nozzles on it?

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

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.

Cheers Tim!
