Printed 2 weeks ago & worked perfectly, now I'm getting this no matter the size.
Excessive stringing, looks like it's bubbling in the print lines, filament sticking to nozzle as its flowing out.
Ender 5+, pla+, stock except for all alloy extruder & capricorn tube.
Temps have been 215-190 for nozzle
Bed 60-65.
Oh & I get the lovely triangle prime line at the start when the geode is normal.
TIA.

Curious... when or if it actually gets to printing, does it fail part way through?

#

Nope, straight away, just been trying to do a retraction test, as the filament starts to print, part of it will the stick to the nozzle which in turn just curls the filament up and not touching the bed.

#

I'm currently letting it going through it's motion to lay the base and will stop it before the sticks, to see how it looks.

#

This is 3 layers of printing the retraction test

The first thing to look at is definitly adhesion. Being too close to the bed can cause a clog, and too far and it'll not stick to the bed (and more likely the nozzle)

#

Clean the bed and maybe add an adhesive to it. If there's clogging, raise the nozzle a bit by adjusting the z offset

#

Could be part of the problem, don't use too much pressure when using pliers to remove filament around nozzle.

How...

#

To have that much force though

desert ferry
#

too much pressure take filament off around the end of the nozzle

#

I'm just in awe

#

So I seem to have fixed it, looks like nozzle was loose by a bees d**k, which allowed filament to pool on top of heat break, obviously need allowing all filament out of nozzle.

#

I mean... a messed up nozzle would do that

#

Retraction test just finished

#

No for the real test an actual long print.

#

My ender 5 is weird eith it's issue

#

It doesn't arise unless the print is more than 2 hours in

#

And after failing, it fixes itself

#

I've been doing flexi print lately, but the latest one doesn't even get through the first layer without failing, which is about a 16 hr print, but we'll see how it goes this time.

#

I'm also trying to upgrade at the same time but no printing means no upgrades

#

And the triangle prime line is lots of fun too, NOT.
