My ender 5 plus apparently has a common problem, but I may have found a
cure.

The ejector driver, on the rear frame of the 5 plus, has a smaller, brass
version on the bowden tube holder coming out of the top of it, and this
fitting doesn't grip the tube, even capricorn, tightly enough to keep it
from wearing out and alowing the tube to slip, screwing with your
retraction settings and probably other things.

https://www.thingiverse.com/thing:3331556

Might be the magic twanger that will fix it for a long period of time.
He's  found that 10-32 nuts will screw onto the bowden tube, and a stack
of at least 3 holds it tight without restricting the bore of the tubing.

I had ordered replaements when I discovered it while rebuilding the
bowden tube while installing a ruby nozzle, which will allow me to use
carbon fiber filament. But I couldn't get either end of the tube out of
the old fittings and had to cut them off, leaving the tube too short.
And the new one I just unbagged also slipped, so I went hunting and
found the above fix, the first part of which is printing now.

I hope others find this usefull. No source files, only .stl's. But if
your printer uses a different sized fitting, it should not be too
difficult to make in openscad.

I also fitted a small steel washer under the hot end fitting, trapping a
slightly overlength piece of capricorn between the fitting and the back
of the nozzle, stopping the leakage, and the growth of an oversized end
on the filament that precludes withdrawing the filament to change it.
Just make sure both ends are sanded as dead flat as you can make them.
And stick a couple inches of filament clear to the nozzle while
assembling it to hold the washer centered.

Cheers, Gene Heskett

Interesting idea. I've been using a similar approach where I've scrapped
the pneumatic connector completely in favour of an M4 nut in my setups.

I pulled that too, looks interesting until I tried to screw some ptfe
bowden tubing into an M4 by .7 nut. It WILL have to be threaded as it
will not catch and be cut into the tube by the common nut. And in a
flexing joint like the top of the extruder on an E5+, would weaken the
tubing with that depth of cut, so to improve on the 10-32 fit and grip,
a slightly deeper cut and better grip might be to try a 10-24 nut, which
might not cut quite as deeply as an m4, but would cut a bit deeper than
a 10-32. Worth trying anyway. I'll get both tomorrow. If push comes to
shove, I have all three dies too. With a ruby .4 nozzle, it looks to be
almost under extruded, and allows a thou or so of end play yet, so I
might try upping the flow in cura.

Nah there's no issue with the depth of cut of an M4 nut -- my bowden
tube's been running on a delta for something like 4 years now and gone
through some 2-digit number of 1kg reels with absolutely no damage.

Also I'm not sure whether you meant that the bowden tube needed to be
threaded with a die, but just to confirm, I did not use one. I just
screwed a standard M4 nut onto the tube using the threading tool I
linked above, then left it permanently installed on the tube.

It refuses to catch and start the thread if you don't use the tool, but
once you thread it on using the tool, it goes on quite easily without
any fuss.

It looks like it should work, but I can't get it started square. How did
you do it? Or did you start the threading with a die for a couple turns?
I'm playing with white ptfe, not capricorn, but have capricorn on the
printer. And I have the dies, out in the garage. But since the link I
posted is for a kit that fits the 'merican 10-xx hex nuts, larger across
the flats than a 4mm, I'll get those too as I do have the dies for all
3.

I also read that the whole tube is worn by the abrasiveness of CF
filament, which I have 2 rolls of in pricy PETG on the shelf.  Going to
make a smaller harmonic drive with it. If I can. Something I can drive
with a longer nema 17. A axis for a 6040.  Have you tried a CF filament
in your printer?

threaded as it will not catch and be cut into the tube by the
common nut. And in a flexing joint like the top of the extruder on
an E5+, would weaken the tubing with that depth of cut, so to
improve on the 10-32 fit and grip, a slightly deeper cut and
better grip might be to try a 10-24 nut, which might not cut quite
as deeply as an m4, but would cut a bit deeper than a 10-32. Worth
trying anyway. I'll get both tomorrow. If push comes to shove, I
have all three dies too. With a ruby .4 nozzle, it looks to be
almost under extruded, and allows a thou or so of end play yet, so
I might try upping the flow in cura.

Nah there's no issue with the depth of cut of an M4 nut -- my bowden
tube's been running on a delta for something like 4 years now and
gone through some 2-digit number of 1kg reels with absolutely no
damage.

Also I'm not sure whether you meant that the bowden tube needed to be
threaded with a die, but just to confirm, I did not use one. I just
screwed a standard M4 nut onto the tube using the threading tool I
linked above, then left it permanently installed on the tube.

It refuses to catch and start the thread if you don't use the tool,
but once you thread it on using the tool, it goes on quite easily
without any fuss.

That referenced tool needs MCAD, but I've forgotten where to put it so
openscad finds it. I do have it on hand from a month or so ago. I
thought it went in $HOME/.local but I don't see BOSL2 there either. So
where does it get put?

Use the dev branch of MCAD: https://github.com/openscad/MCAD/tree/dev.
You can put it in the same folder as the .scad from the thingiverse link
and it should pick things up correctly.

Nope, the dev branch has it called mcad_polyhole.

No help, in either location, 28 show stopping errors, Loong jin.
So I printed the other, older gizmo that supposedly used 10-32 nuts
I tried 10-32's, in the other holder, too sloppy, but 10-24's stacked
full, 5 of them are holding completely solid. I'll run that way till
